It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

It should be noted that the electronic device in the embodiment of the present application is mainly directed to an electronic device having a flexible screen structure, where the flexible screen is folded or unfolded in the electronic device in a telescopic manner. It can be understood that the electronic device in the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and other electronic devices having a flexible screen structure.

The flexible screen is a trend of a future whole machine design scheme, and the display panel can be designed into various shapes according to requirements by utilizing the characteristic that the flexible screen can be bent at will, such as a display panel structure which can be curled or folded.

Based on this, the applicant found in research that the flexible screen has a limited area to be reduced by adopting the folding display panel structure, and the area of the flexible screen can be reduced by half by adopting the folding display panel structure. In addition, the thickness of the folding electronic apparatus is almost doubled when it is folded, and the sense of compactness is lacking.

In order to solve the problems, the technical scheme of the embodiment of the application is that a flexible screen slides and stretches, so that a smaller display area can be achieved when the screen is folded, and a larger display area can be achieved when the screen is unfolded. Meanwhile, the thickness of the electronic device is almost unchanged when the screen is folded or unfolded.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of anelectronic device 1000 according to some embodiments of the present application, and fig. 2 is a schematic structural diagram of theelectronic device 1000 according to fig. 1. Theelectronic device 1000 may generally include afirst housing 100, asecond housing 200, aflexible screen 300, and asupport apparatus 400. Wherein thefirst housing 100 and thesecond housing 200 are slidably coupled. The X, Y and Z directions of theelectronic device 1000 are shown in fig. 1, mainly to illustrate the sliding direction of thesecond casing 200 relative to thefirst casing 100 and the XY, XZ and YZ planes, so as to facilitate the corresponding description hereinafter. Specifically, the Z direction shown in fig. 1 is approximately the thickness direction of theelectronic apparatus 1000, the Y direction is approximately the sliding direction of thesecond housing 200 with respect to thefirst housing 100, and the XY plane is approximately parallel to the display surface of theelectronic apparatus 1000.

Referring to fig. 3 and 4 in combination, fig. 3 is a schematic structural view of thesecond housing 200 of the embodiment of fig. 1 when it is closed relative to thefirst housing 100, and fig. 4 is a schematic structural view of thesecond housing 200 of the embodiment of fig. 1 when it is unfolded relative to thefirst housing 100.

Thefirst casing 100 may include afirst sidewall 110, asecond sidewall 120, and afirst bottom wall 150 connecting thefirst sidewall 110 and thesecond sidewall 120, wherein thefirst sidewall 110, thesecond sidewall 120, and thefirst bottom wall 150 together enclose a groove structure having theaccommodating cavity 101.

In some embodiments, thefirst casing 100 may further include athird sidewall 130, and thethird sidewall 130 is disposed between thefirst sidewall 110 and thesecond sidewall 120 and located on a side of thefirst bottom wall 150 away from thesecond casing 200. Thethird sidewall 130 is an arc-shaped sidewall, and thethird sidewall 130 is connected to thefirst bottom wall 150 in a bending manner. Thethird sidewall 130 cooperates with thefirst sidewall 110, thesecond sidewall 120 and thefirst bottom wall 150 to form the above-mentioned groove with theaccommodating cavity 101.

Thesecond housing 200 is partially accommodated in theaccommodating cavity 101 of thefirst housing 100, and thesecond housing 200 is configured to be partially retractable in theaccommodating cavity 101, i.e., thesecond housing 200 can slide in the Y direction relative to thefirst housing 100.

Thesecond housing 200 is substantially a drawer groove structure, and the opening of the drawer groove faces thefirst housing 100. Specifically, thesecond casing 200 generally includes afirst side frame 210, asecond side frame 220, athird side frame 230, and afourth side frame 240 connected end to end in sequence, and thesecond casing 200 may further include asecond bottom wall 250 far from thefirst casing 100. Thefirst side frame 210, thesecond side frame 220, thethird side frame 230, and thefourth side frame 240 are respectively connected with the secondbottom wall 250 in a bending manner, so as to form a drawer slot with an opening facing thefirst casing 100 and anaccommodating space 201, wherein theaccommodating space 201 of the drawer slot is communicated with theaccommodating cavity 101.

Further, thefirst side frame 210 and thethird side frame 230 are disposed opposite to each other, and thesecond side frame 220 and thefourth side frame 240 are disposed opposite to each other. Thefirst side frame 210 and thethird side frame 230 are slidably connected to thefirst side wall 110 and thesecond side wall 120 of thefirst casing 110, respectively, so that thesecond casing 200 can be slidably opened and closed with respect to thefirst casing 100. Thefourth side frame 240 is adjacent to or in contact with the firstbottom wall 150, and thesecond side frame 220 is located on a side of thefourth side frame 240 facing away from the firstbottom wall 150.

Taking thefirst side frame 210 and thefirst side wall 110 as an example, please refer to fig. 5, fig. 5 is a schematic structural view of a portion of thesecond casing 200 and thefirst casing 100 in the embodiment of fig. 1, it can be understood that the sliding connection manner of thethird side frame 230 and thesecond side wall 120 is substantially the same as the sliding connection manner of thefirst side frame 210 and thefirst side wall 110, and therefore, repeated descriptions are omitted.

Specifically, thefirst side frame 210 generally includes a slidingportion 211 and astopper portion 212. The slidingportion 211 and the stoppingportion 212 may be an integrally formed structure. Specifically, the slidingportion 211 is disposed at an end of thestopper portion 212 close to thefirst sidewall 110, and is slidably connected to thefirst sidewall 110.

Further, the cross-sectional area of the slidingpart 211 along the XZ plane is smaller than the cross-sectional area of the stoppingpart 212 along the XZ plane. Preferably, the slidingportion 211 and the stoppingportion 212 are disposed adjacent to a surface of theaccommodating space 201 in a coplanar manner, and the slidingportion 211 and the stoppingportion 212 are disposed away from the surface of theaccommodating space 201 in a step structure. The thickness of the slidingpart 211 in the Z direction is smaller than that of the stoppingpart 212 in the Z direction, that is, two surfaces of the slidingpart 211 opposite to each other in the Z direction are respectively arranged in a step structure with the corresponding surface of the stoppingpart 212.

Thefirst side wall 110 is provided with a first slidinggroove 1111 extending in the Y direction, and the slidingportion 211 is configured to be slidable in the Y direction within the first slidinggroove 1111. The bottom wall of the first slidinggroove 1111 is further provided with a second slidinggroove 1112 extending in the Y direction, and the slidingportion 211 is provided with a slidingstrip 2111 corresponding to the second slidinggroove 1112. Theslide bar 2111 is configured to be slidable in the Y direction within thesecond chute 1112. It can be understood that, by opening the second slidinggroove 1112 in the bottom wall of the first slidinggroove 1111 and providing the slidingstrip 2111 on the slidingportion 211, the slidingstrip 2111 can slide in the second slidinggroove 1112, and at the same time, the slidingportion 211 can be limited in the X direction and the Z direction during the sliding process of the slidingportion 211. It should be noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

In the present embodiment, the surface of the stoppingportion 212 facing away from the inside of theelectronic device 1000 and the surface of thefirst groove 1111 facing away from the inside of theelectronic device 1000 are coplanar, so that theelectronic device 100 has better appearance when thesecond casing 200 and thefirst casing 100 are slidably closed.

In this embodiment, thesecond housing 200 connects and supports a portion of theflexible screen 300. Preferably, thesecond side frame 220 of thesecond casing 200 is provided with agroove 221, and thegroove 221 is used for accommodating a portion of theflexible screen 300, that is, theflexible screen 300 is partially attached to thegroove 221. Theflexible screen 300 may be adhered to thegroove 221 by glue, for example, theflexible screen 300 and thegroove 221 may be adhered by double-sided tape, optical tape, or the like. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

Wherein theflexible screen 300 is configured to be switchable between a large screen state and a small screen state by means of telescoping. When theflexible screen 300 is in a small screen state, that is, when thefirst casing 100 and thesecond casing 200 are closed, a part of theflexible screen 300 is accommodated in the inner space of thefirst casing 100 and thesecond casing 200, that is, the inner part of theelectronic device 1000, and another part of theflexible screen 300 is directly exposed on the surface of thesecond casing 200, so that theflexible screen 300 can achieve a small screen display effect. Further, the portion of theflexible screen 300 exposed on the surface of thesecond housing 200 is attached to thegroove 221, so that thesecond housing 200 can support and fix the portion of the exposedflexible screen 300, and further thesecond housing 200 can synchronously drive the flexible screen to move when supporting the portion of the flexible screen.

When theflexible screen 300 is in a large-screen state, that is, when thefirst casing 100 and thesecond casing 200 are unfolded, a portion of theflexible screen 300 attached to thegroove 221 and thesecond casing 200 move synchronously, and a portion of the flexible screen accommodated in theelectronic device 1000 is gradually pulled out, so that theflexible screen 300 can achieve a large-screen display effect. The supportingdevice 400 is configured to be able to support a portion of theflexible screen 300 drawn out from the inner space of the first andsecond housings 100 and 200. The supportingdevice 400 is installed in theaccommodating cavity 101 of thefirst housing 100 to position the supportingdevice 400.

The electronic equipment provided by the embodiment of the application can be switched between a large screen state and a small screen state at will by the aid of the first shell and the second shell which are connected in a sliding mode, and different display effects are achieved. In addition, in the process of opening and closing the first shell and the second shell, the whole thickness of the electronic equipment is almost kept unchanged, so that the use experience of a user is improved.

Referring to fig. 6 to 7 in combination, fig. 6 is a schematic structural diagram of theelectronic device 1000 in the embodiment of fig. 1 in a large-screen state, where fig. 1 is a schematic structural diagram of thefirst housing 100 and thesecond housing 200 when they are closed, that is, theflexible screen 300 is in a small-screen state, and fig. 6 is a schematic structural diagram of thefirst housing 100 and thesecond housing 200 when they are unfolded. Fig. 7 is a schematic structural disassembly diagram of theelectronic device 1000 in the embodiment of fig. 6.

Theflexible screen 300 may generally include a firstflexible portion 310 and a secondflexible portion 320 that are integrally formed. The firstflexible portion 310 is attached to thesecond housing 200 and moves synchronously with the movement of thesecond housing 200. That is, the firstflexible portion 310 may be adhesively connected to thegroove 221 of thesecond side frame 220 by glue. The supportingdevice 400 can support the secondflexible portion 320, so that theflexible screen 300 can be supported more completely in a large screen state, and the risk that the secondflexible portion 320 sinks or is recessed due to no support is avoided, and further, the user experience and the display effect are not affected. It should be noted that the dashed lines in fig. 6 and 7 are only for illustrating the approximate boundaries of the firstflexible portion 310 and the secondflexible portion 320.

It can be understood that when theelectronic device 1000 is in the small screen state shown in fig. 1, the firstflexible portion 310 is exposed on the surface of thesecond casing 200 and is supported by thesecond casing 200. When theelectronic device 1000 moves from the small-screen state shown in fig. 1 to the large-screen state shown in fig. 6, the secondflexible portion 320 is exposed out of thefirst casing 100, and at this time, the supportingdevice 400 moves to a position supporting the secondflexible portion 320, so that the exposed area of theflexible screen 300 can be simultaneously supported by thesecond casing 200 and the supportingdevice 400, and the poor use experience caused by the unsupported area of the secondflexible portion 320 can be avoided.

Referring to fig. 8 and fig. 9, an embodiment of the present application further provides a supportingdevice 400 applied to theelectronic apparatus 1000, so that when theelectronic apparatus 1000 is in a large screen state, the supportingdevice 400 is configured to support the secondflexible portion 320 of theflexible screen 300, so that the display surface of theflexible screen 300 can be supported more completely. Fig. 8 is a schematic structural diagram of the supportingdevice 400 when theelectronic device 1000 is in a small-screen state, and fig. 9 is a schematic structural diagram of the supportingdevice 400 when theelectronic device 1000 is in a large-screen state.

In the following embodiments, a supporting direction in which theflexible screen 300 is supported by the supportingdevice 400 is defined as a first direction, and a telescopic direction of theflexible screen 300 is defined as a second direction. In other words, thesupport device 400 can support theflexible panel 300 in the Z direction, and theflexible panel 300 can be extended and contracted in the Y direction. Wherein the Y-direction is substantially perpendicular to the Z-direction, i.e. theflexible screen 300 is configured to be able to telescope in a direction perpendicular to the first direction.

Thesupport apparatus 400 may generally include astationary assembly 410, asupport assembly 430, and a connectingassembly 450. The fixingassembly 410 is used to mount the supportingdevice 400 inside theelectronic apparatus 1000 to position the supportingdevice 400. Thesupport assembly 430 is for supporting theflexible screen 300 of theelectronic device 1000, i.e. thesupport assembly 430 is configured to be able to support the secondflexible portion 320 of theelectronic device 1000. The connectingassembly 450 serves to connect the fixingassembly 410 and the supportingassembly 430 to constitute an integral structure of the supportingdevice 400. Wherein the supportingmember 430 and the fixingmember 410 are stacked in a supporting direction of the supportingdevice 400, i.e., a first direction, and the supportingmember 430 is configured to be movable in the first direction with respect to the fixingmember 410.

The fixingelement 410 is fixedly disposed in theaccommodating cavity 101 of thefirst housing 100, and further limits the supportingelement 430 in theaccommodating cavity 101 of thefirst housing 100. Thesupport assembly 430 is configured to be able to telescope with respect to theaccommodating space 201, that is, thesupport assembly 430 is configured to support the secondflexible portion 320 when the secondflexible portion 320 extends out. In addition, when the secondflexible portion 320 is retracted inside theelectronic device 1000, the supportingmember 430 moves toward the fixingmember 410 in the Z direction to sink, thereby providing a space for thesecond housing 200 to be closed; when thesecond housing 200 is moved to a predetermined position in a direction away from thefirst housing 100 when the secondflexible portion 320 is extended, the supportingmember 430 is moved in a direction away from the fixingmember 410 in the Z direction to be lifted up, thereby supporting the secondflexible portion 320.

It will be appreciated that the lowering and raising of thesupport assembly 430 may be accomplished by theconnection assembly 450. That is, the position where the fixingmember 410 is fixedly disposed inside theelectronic device 1000 may not be changed, and thesupport member 430 can be lowered or raised by changing the position of the connectingmember 450.

As described above, theflexible screen 300 is configured to be capable of telescoping with respect to the fixedmember 410, and theconnection member 450 is capable of sliding with respect to the fixedmember 410 in a telescoping direction of theflexible screen 300, thereby achieving a sinking or lifting movement of thesupport member 430 by a positional change of theconnection member 450 with respect to the fixedmember 410. Wherein, the connectingcomponent 450 is slidably connected with the fixingcomponent 410, and the connectingcomponent 450 is slidably connected with the supportingcomponent 430. Further, the connectingassembly 450 is slidable relative to the fixingassembly 410 in a direction perpendicular to the first direction; and the connectingassembly 450 is configured to be slidable relative to thesupport assembly 430. In other words, the connectingassembly 450 can slide in different directions relative to the supportingassembly 430 in different strokes, thereby achieving sinking or lifting of the supportingassembly 430.

The supporting device that this application embodiment provided can support the flexible portion when the second flexible portion of flexible screen stretches out through setting up the supporting component that can move in the direction of supporting the flexible screen for fixed subassembly. In addition, the support assembly is movable relative to the fixed assembly when the second flexible portion of the flexible screen is retracted, thereby causing the support assembly to exit the supported state and retract into the second housing. This application embodiment can support the flexible screen of the part that stretches out from electronic equipment through locating the inside supporting component of electronic equipment promptly, and the casing and the supporting component of electron equipment are selectively utilized to the ingenious to adopt different bearing structure when flexible screen stretches out or withdraws, and then can simplify electronic equipment overall structure.

Specifically, the supportingdevice 400 may further include a fixingshaft 470, and opposite ends of the fixingshaft 470 are respectively connected to the first andsecond sidewalls 110 and 120 of thefirst housing 100. The fixingplate 411 and the fixingshaft 470 are coupled to position the fixingplate 411 within the receivingcavity 101. The slidinggroove 412 extends along the telescopic direction (i.e., Y direction) of theflexible screen 300.

Thesupport assembly 430 may generally include asupport plate 431 and aslide member 432, theslide member 432 being provided at a side of thesupport plate 431 adjacent to the fixedplate 411. Thesupport plate 431 is configured to support theflexible screen 300, that is, thesupport plate 431 is supported to the secondflexible portion 320 of theflexible screen 300 when theflexible screen 300 is extended to a large screen state. Theslider 432 is configured to be movable in a telescopic direction (i.e., Y direction) of theflexible screen 300 to move thesupport plate 431 in the Y direction. Meanwhile, the slidingpart 432 is also configured to be movable along the supporting direction (i.e., Z direction) of the supportingdevice 400 to bring the supporting plate to move along the Z direction.

Theconnection assembly 450 may generally include aslide rail 451, and theslide rail 451 may be configured to be movable relative to theslide groove 412 in a telescopic direction (i.e., Y direction) of theflexible screen 300.

Theslide rail 451 and theslide groove 412 are slidably connected, and theslide rail 451 and theslide groove 412 can slide in the Y direction. The slidingmember 432 is slidably connected to theslide rail 451, and the slidingmember 432 is configured to be slidable relative to theslide rail 451 in a direction away from the fixedplate 411 or close to the fixedplate 411.

In the present embodiment, the slidinggroove 412 and the fixingplate 411 are integrally formed, that is, the slidinggroove 412 may be directly formed at the edge of the fixingplate 411 through an integral forming process such as stamping. Two slidinggrooves 412 may be provided, and the two slidinggrooves 412 are respectively provided at two edges of the fixingplate 411 extending along the Y direction. Correspondingly, two slidingmembers 432 and two slidingrails 451 may be respectively provided, the two slidingmembers 432 are respectively provided on two edges of the supportingplate 431 extending along the Y direction, and the two slidingrails 451 are respectively connected with the corresponding slidingmembers 432 and the slidinggrooves 412 in a sliding manner.

When theelectronic device 1000 is in a small screen state, theslide rail 451 is completely disposed on the fixingplate 411; when theelectronic apparatus 1000 is in a large screen state, theslide rail 451 is at least partially staggered with the fixingplate 411.

Thefirst slide 4511 is slidably connected to theslide groove 412. When the end of the first slidingway 4511 facing away from the fixedshaft 470 does not protrude from the slidinggroove 412, i.e., the first slidingway 4511 substantially completely overlaps with the sliding groove 412 (as shown in fig. 11), theelectronic apparatus 1000 is in a small-screen state. At this time, the interval between thesupport plate 431 and the fixingplate 411 is minimized, and thesupport plate 431 is received in the receiving space of thesecond housing 200. When thefirst slide 4511 slides relative to theslide groove 412 from the state of fig. 11 to the state of fig. 12, that is, when thefirst slide 4511 at least partially protrudes from theslide groove 412, theelectronic apparatus 1000 is in the large-screen state. At this time, the interval between thesupport plate 431 and the fixingplate 411 is maximized, and thesupport plate 431 and thesecond housing 200 support theflexible screen 300 together. That is, thesupport plate 431 is supported by the secondflexible portion 320, and the second housing is supported by the firstflexible portion 310.

Second slide 4512 is slidably connected to slide 432. The slidingpart 432 generally includes a slidingportion 4321 and aclamping portion 4322, which are connected in a bending manner, the slidingportion 4321 is disposed on one side of the supportingplate 431 close to the fixingplate 411, and theclamping portion 4322 extends from the slidingportion 4321 toward thesecond slideway 4512. Wherein, the clampingportion 4322 is slidably connected to thesecond slide rail 4512, the clampingportion 4322 is configured to be able to slide relative to thesecond slide rail 4512 along the Y direction, and theclamping portion 4322 is configured to be able to slide relative to thesecond slide rail 4512 along a direction away from the fixingplate 411 or close to the fixingplate 411.

In this embodiment, thefirst slide 4511 and thesecond slide 4512 are integrally formed. Namely, theslide rail 451 having thefirst slide way 4511 and thesecond slide way 4512 which are oppositely arranged may be directly formed through an integral molding process such as stamping.

Referring to fig. 13, fig. 13 is a schematic structural diagram of the slidingrail 451 and the slidingmember 432 according to some embodiments of the present disclosure. Theslide rail 451 may generally include anupper rail 4513, alower rail 4514, and aweb 4515 connecting theupper rail 4513 and thelower rail 4514. Therail web 4515 is respectively connected to the middle positions of theupper rail 4513 and thelower rail 4514 so as to cooperate with theupper rail 4513 and thelower rail 4514 to enclose thefirst slide rail 4511 and thesecond slide rail 4512 which are arranged oppositely. In the present embodiment, theupper rail 4513 is disposed adjacent to thesupport plate 431, and thelower rail 4514 is disposed adjacent to the fixingplate 411.

One side of theupper rail 4513, which is close to the slidingpart 432, is provided with a clampinggroove 45131 communicated with thesecond slide rail 4512. The snap-inportion 4322 and the snap-ingroove 45131 cooperate such that thesupport plate 431 can be used to support theflexible screen 300. Specifically, when the clampingportion 4322 moves from thesecond slide 4512 to the clampinggroove 45131 and is matched with the clampinggroove 45131, the clampingportion 4322 drives the slidingmember 432 to move in a direction away from the fixingplate 411, so that the supportingplate 431 moves in a direction away from the fixingplate 411, and the supportingplate 431 can be used for supporting theflexible screen 300. When the clampingportion 4322 moves from the clampinggroove 45131 to thesecond slide rail 4512 and is engaged with thesecond slide rail 4512, the clampingportion 4322 drives the slidingmember 432 to move toward the fixedplate 411, so that the supportingplate 431 moves toward the fixedplate 411, and the supportingplate 431 sinks and separates from theflexible screen 300.

In other words, the sliding stroke of the clampingportion 4322 includes a first stroke and a second stroke, the first stroke generally refers to the sliding stroke of the clampingportion 4322 sliding in thesecond slide rail 4512, and the second stroke generally refers to the sliding stroke of the clampingportion 4322 sliding in the clampinggroove 45131. The sliding direction of the clampingportion 4322 in the first stroke is the Y direction, and the sliding direction of the clampingportion 4322 in the second stroke intersects with the Y direction. That is, the second stroke of the clampingportion 4322 is inclined relative to the first stroke, or the second stroke and the first stroke of the clampingportion 4322 are substantially perpendicular.

Wherein, the firstinclined surface 43221 and the firstinclined wall 451311 cooperate, and the secondinclined surface 43222 and the secondinclined wall 451312 cooperate to guide the engagingportion 4322 to move in a direction away from the fixingplate 411 or close to the fixingplate 411. It can be understood that, in the present embodiment, the second stroke of the clampingportion 4322 is obliquely arranged compared to the first stroke, so that the clampingportion 4322 can gradually get away from or close to the fixingplate 411.
