The thirdadhesive sheet 315 covers the bottom end of therear surface 13. By providing thesupport plate 31, the back 13 of thedisplay screen 15 can be protected.

For example, the peep-proof membrane 32 includes acover plate 321 and a peep-proof membrane 323, an edge of thecover plate 321 is rotatably connected to a top edge of theback surface 13, thecover plate 321 covers the top surface of thebody 10, a top edge of the peep-proof membrane 323 is rotatably connected to a side edge of thecover plate 321 away from theback surface 13, the peep-proof membrane 323 covers thefront surface 11 of thebody 10 and shields thedisplay screen 15, the peep-proof membrane 323 is a transparent membrane, and is used for displaying an image of thedisplay screen 15 in front of the display screen, so that only a person in front of the display screen can see the displayed image, and a person at the side cannot see the displayed image, thereby implementing the peep-proof function. For example, the length of the peep-proof membrane 32 is equal to the length of thebody 10, i.e. the sum of the lengths of the peep-proof membrane 323 and thecover plate 321 is equal to the length of thebody 10, so that the lower end of the peep-proof membrane 323 exposes thenavigation key 14. For example, in one embodiment, theprivacy film 323 is a tempered film. For example, theprivacy film 323 has elasticity.

For example, the firstadhesive plate 312 and the secondadhesive plate 313 are used for being adhered and fixed on theback surface 13 of thebody 10, the thirdadhesive plate 315 is used for being peeled off from theback surface 13 and being turned over relative to thefirst light plate 314 and adhered on a table top, and thefirst light plate 314 is used for being rotated relative to thebody 10 to obliquely support thebody 10, so as to position thesupport plate 31. Through the operation, the handheld communication device can be obliquely supported on a desktop, so that thedisplay screen 15 can reach a better display angle. When the support is not needed, thethird bonding plate 315 is torn from the table top, and thefirst light plate 314 is attached to theback surface 13, so that thethird bonding plate 315 is attached to theback surface 13 of thebody 10, thereby realizing folding.

For example, in order to achieve more stable support of thebody 10 or change the inclination angle of thebody 10, thebridging component 40 includes twoholders 42 and two elastic pullingstrings 44, the twoholders 42 are both slidably disposed on thefirst light plate 314, the twoholders 42 are disposed at intervals, the two elastic pullingstrings 44 are respectively located at two opposite sides of thefirst light plate 314, and two opposite ends of each elastic pullingstring 44 are respectively connected to the twoholders 42. Specifically, each of theholders 42 includes a connectingplate 421, two hard guide blocks 422 and aflexible pull strip 423, the connectingplate 421 is slidably disposed on a side surface of the firstoptical plate 314 facing away from thebody 10, a length direction of the connecting plate is perpendicular to a length direction of thebody 10, the two hard guide blocks 422 are respectively located on two opposite sides of the firstoptical plate 314, and the two hard guide blocks 422 are respectively slidably disposed in the twoguide grooves 311. Further, each of the hard guide blocks 422 includes amain body 424, alocking block 425 and a connectingprotrusion 426, themain body 424 is located between the firstoptical plate 314 and theback 13 of themain body 10, thelocking block 425 is protruded from one end edge of themain body 424 and slidably locked in thecorresponding guide slot 311, the connectingprotrusion 426 is protruded from the other end edge of themain body 424 and exposed to the outside of the firstoptical plate 314, the connectingprotrusions 426 of the two hard guide blocks 422 are respectively and fixedly connected to opposite ends of the connectingplate 421, opposite ends of theflexible pull string 423 are respectively connected to the connectingprotrusions 426 of the two hard guide blocks 422, theflexible pull strings 423 are parallel to the connectingplate 421 and are spaced from each other, and aninsertion gap 427 is formed between theflexible pull string 423 and the connectingplate 421. The peep-proof membrane 323 is turned 360 degrees and then inserted into theinsertion gap 427. Opposite ends of each of the elastic pullingstrings 44 are respectively connected to theconnection protrusions 426 of the same end of the twoholders 42.

Thesecond bonding plate 313 is further used for being torn from theback surface 13 of thebody 10 and rotating to a position coplanar with the firstoptical plate 314, one of theholders 42 is used for being pushed to a connection position of the firstoptical plate 314 and thesecond bonding plate 313, and the firstoptical plate 314 and thesecond bonding plate 313 are clamped and fixed by two hard guide blocks 422 of theholder 42 so that thesecond bonding plate 313 is kept coplanar with the firstoptical plate 314, and the inclined support of thebody 10 is realized. For example, the bottom surface of thelocking block 425 is provided with a friction surface, which abuts against the bottom surface of the guidinggroove 311 to position the hard guide block 422, and the holdingframe 42 cannot slide down freely due to gravity, because the gravity of the holdingframe 42 is much smaller than the friction force between the holdingframe 42 and the bottom surface of the guidinggroove 311. When the support is not needed, the twoholders 42 are pushed to move to the middle of thefirst light plate 314 by force, thethird bonding plate 315 is torn from the table top, and thefirst light plate 314 is attached to theback surface 13, so that thesecond bonding plate 313 and thethird bonding plate 315 are both attached to theback surface 13, and the folding is realized. At this time, the hard guide blocks 422 of the twoholders 42 will abut against each other to slightly arch the firstoptical plate 314, but the firstoptical plate 314 can be elastically deformed to adapt to the change without much influence.

For example, the firstadhesive plate 312 is further configured to be torn from theback surface 13 of thebody 10 and rotated to a position coplanar with the secondadhesive plate 313, wherein theother holder 42 is configured to be pushed to a connection position of the firstadhesive plate 312 and the secondadhesive plate 313, and the firstadhesive plate 312 and the secondadhesive plate 313 are clamped by the two hard guide blocks 422 of theholder 42 so that the firstadhesive plate 312 is maintained coplanar with the secondadhesive plate 313, so that thebody 10 is obliquely supported by the firstoptical plate 314, the firstadhesive plate 312 and the secondadhesive plate 313. Since the first and secondadhesive regions 3131 and 3131 are located between the twoguide grooves 311, the hard guide blocks 422 of the twoholders 42 are located at theguide grooves 311 and do not touch the first and secondadhesive regions 3131 and 3131, so that the twoholders 42 can smoothly slide. For example, the elastic force of the twoelastic cords 44 is set to be small, and the elasticity thereof is set to be large, that is, the tensile force of theelastic cords 44 is not enough to pull the twoholders 42 close to each other. For example, the distance between the top edge and the bottom edge of the secondadhesive sheet 313 is defined as the width of the secondadhesive sheet 313, and the original length of theelastic cord 44 is equal to the width of the secondadhesive sheet 313. Therefore, the tworetainers 42 can be respectively positioned at the top edge and the bottom edge of the secondadhesive plate 313, and are not close to each other by large elastic force, so that the bridging and clamping functions of the tworetainers 42 can be realized. When the light panel needs to be disassembled, the twoholders 42 are pushed onto thefirst light panel 314 by force.

For example, an adhesive area is disposed at the bottom end of thefront surface 11 of theprivacy film 323, the middle portion of theprivacy film 323 is attached to thefront surface 11 by vacuum, and is detachably fixed to thefront surface 11 by the adhesive area. In order to improve the supporting tension of the supportingplate 31, a latchinggroove 3155 is formed in a side surface of thethird bonding plate 315 away from thebody 10, the latchinggroove 3155 is located at an edge of thethird bonding plate 315 away from thefirst light plate 314, the peep-proof membrane 323 is further used for tearing off thefront surface 11 of thebody 10 and driving thecovering plate 321 to turn over to theback surface 13, the middle of the peep-proof membrane 323 penetrates through twoinsertion gaps 427 of the twoholders 42, and the end of the peep-proof membrane 323 is latched in the latchinggroove 3155 of thethird bonding plate 315, so that the peep-proof membrane 323 is integrally bent into an arch shape, and the supporting tension of the supportingplate 31 is further improved. When not needed, the peep-proof membrane 323 can be pulled away from thesupport plate 31, turned over to thefront surface 11 of thebody 10, and attached and fixed on thefront surface 11 of thebody 10 again. Through the arrangement of the supportingplate component 30 and thebridging component 40, the handheld communication device can be supported at a plurality of inclination angles in a plurality of ways, so that the supporting convenience is improved, and a plurality of better display angles can be conveniently displayed. While the twoflexible pull straps 423 are capable of holding the middle portion of theprivacy film 323. In addition, when the supportingplate 31 is integrally attached and fixed to theback 13 of themain body 10, the two flexible pullingstraps 423 are further used for tying a hanging rope, so that the user can hang the handheld communication device by using the hanging rope, for example, the handheld communication device is tied to the waist or hung in front of the chest, and is suitable for being carried by pupils. For example, since theentire support plate 31 in the supported state is bent, the peep-proof membrane 323 is also inserted in thesupport plate 31 so as to be bent.

For example, the internet-based vegetation identification method further includes a supporting step including:

tearing the thirdadhesive plate 315 from the back 13 of thebody 10 and turning over thefirst light plate 314, adhering and fixing the thirdadhesive plate 315 on a table top, and rotating thefirst light plate 314 relative to thebody 10 to obliquely support thebody 10;

tearing thesecond bonding plate 313 from the back 13 of thebody 10, rotating to a position coplanar with thefirst light plate 314, pushing one of theholders 42 to a joint of thefirst light plate 314 and thesecond bonding plate 313, and clamping thefirst light plate 314 and thesecond bonding plate 313 by using the two hard guide blocks 422 of theholder 42 so as to enable thesecond bonding plate 313 to be kept coplanar with thefirst light plate 314;

the firstadhesive plate 312 is peeled off from theback surface 13 of thebody 10 and rotated to a position coplanar with the secondadhesive plate 313, theother holder 42 is pushed to the joint of the firstadhesive plate 312 and the secondadhesive plate 313, the first adhesive plate and the secondadhesive plate 313 are clamped by the two hard guide blocks 422 of theholder 42 so that the firstadhesive plate 312 is kept coplanar with the secondadhesive plate 313, and thebody 10 is obliquely supported by the firstoptical plate 314, the firstadhesive plate 312 and the secondadhesive plate 313; and

tearing the peep-proof membrane 323 away from thefront surface 11 of thebody 10 and driving thecover plate 321 to turn over to theback surface 13, inserting the middle part of the peep-proof membrane 323 into the twoinsertion gaps 427 of the two holdingframes 42, and clamping the end part of the peep-proof membrane 323 in theclamping groove 3155 of thethird bonding plate 315, so that the peep-proof membrane 323 is integrally bent into an arch shape, thereby improving the supporting tension of the supportingplate 31.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
