为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

以下结合附图，详细说明本申请各个实施例公开的技术方案。The technical solutions disclosed in various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

针对相关技术的内窥镜在使用过程中需要操作者手动维持固定拨杆而导致的操作繁琐的技术问题，本申请实施例提供了一种手柄，应用于内窥镜。Aiming at the technical problem of cumbersome operation caused by requiring the operator to manually maintain and fix the lever during use of the endoscope in the related art, the embodiment of the present application provides a handle, which is applied to the endoscope.

请参见图1～图6，本申请实施例公开的手柄100包括拨动件120、锁止件130、套管140、牵引轮150和弹性件160。Referring to FIGS. 1 to 6 , thehandle 100 disclosed in the embodiment of the present application includes atoggle member 120 , alocking member 130 , a bushing 140 , atraction wheel 150 and anelastic member 160 .

手柄100包括壳体110，壳体110为手柄100的基础构件，其作为其他构件的安装基础，并能够为设于其内部容置腔111的构件提供防护作用。在本申请的实施例中，套管140、牵引轮150等均设于容置腔111内。Thehandle 100 includes ahousing 110 , which is a basic component of thehandle 100 , serves as a base for installing other components, and can provide protection for the components disposed in theaccommodating cavity 111 inside thehandle 100 . In the embodiment of the present application, the bushing 140 , thetraction wheel 150 and the like are all disposed in theaccommodating cavity 111 .

牵引轮150可转动地设于容置腔111内，牵引绳190套设于牵引轮150上，在牵引轮150转动时牵引绳190随动而对其远端的主动弯曲段进行牵拉，从而实现了内窥镜的插入部200的弯曲动作。在本申请的实施例中，牵引轮150开设有第一容置空间151a，拨动件120设于第一容置空间151a内，相当于拨动件120嵌设在牵引轮150内部，通过控制拨动件120即可带动牵引轮150转动；当然，拨动件120需延伸至壳体110外部，从而便于操作者对拨动件120进行操控，壳体110上可开设有第一避让口112，用以供拨动件120穿设。Thetraction wheel 150 is rotatably arranged in theaccommodating cavity 111, and thetraction rope 190 is sheathed on thetraction wheel 150. When thetraction wheel 150 rotates, thetraction rope 190 follows and pulls the active bending section at the far end, thereby The bending action of theinsertion portion 200 of the endoscope is realized. In the embodiment of the present application, thetraction wheel 150 is provided with a firstaccommodating space 151a, and thetoggle member 120 is arranged in the firstaccommodating space 151a, which is equivalent to that thetoggle member 120 is embedded inside thetraction wheel 150. The togglingmember 120 can drive thetraction wheel 150 to rotate; of course, the togglingmember 120 needs to extend to the outside of thecasing 110, so as to facilitate the operator to manipulate the togglingmember 120, and thecasing 110 can be provided with afirst avoidance port 112 , for thetoggle piece 120 to pass through.

其中，本申请的实施例对牵引绳190的数量不做限制，其可以为一条、两条(如图2～图4所示)、四条等。Wherein, the embodiment of the present application does not limit the number oftraction ropes 190 , which may be one, two (as shown in FIGS. 2 to 4 ), four and so on.

在本申请的实施例中，拨动件120沿其轴向可移动地设于第一容置空间151a内，也就是说，拨动件120能够在第一容置空间151a内与牵引轮150产生相对移动，且移动方向位于拨动件120自身的轴向上，该结构特征具体表征为，操作者可按压拨动件120而使拨动件120在牵引轮150内部沿轴向移动。其中，拨动件120可以为拨杆、把手等结构形式。In the embodiment of the present application, thedriving member 120 is movably arranged in the firstaccommodating space 151a along its axial direction, that is to say, thedriving member 120 can be connected to thetraction wheel 150 in the firstaccommodating space 151a. Relative movement is generated, and the moving direction is located in the axial direction of thedriving member 120 itself. This structural feature is specifically characterized in that the operator can press thedriving member 120 to make thedriving member 120 move axially inside thetraction wheel 150 . Wherein, thetoggle member 120 may be in the form of a lever, a handle, and the like.

与此同时，锁止件130与拨动件120固定连接，且自牵引轮150的端面一侧延伸至套管140内，弹性件160与拨动件120相连，用以向拨动件120施加预紧力，以使锁止件130随拨动件120移动至与套管140抵接的位置。At the same time, thelocking piece 130 is fixedly connected with thetoggle piece 120, and extends from the side of the end face of thetraction wheel 150 into thecasing 140, and theelastic piece 160 is connected with thetoggle piece 120 for applying force to thetoggle piece 120. The pre-tightening force is used to make thelocking member 130 move with thetoggle member 120 to a position where it abuts against the bushing 140 .

可以理解，锁止件130和拨动件120基于二者的固接关系，拨动件120在移动时会带动锁止件130移动。其中，弹性件160基于其自身的弹性特性，其在储能状态下会向拨动件120施加预紧力，拨动件120在预紧力的作用会被驱动或存在移动趋势，以使拨动件120能够沿与操作者的按压方向的相反方向移动。It can be understood that, based on the fixed relationship between thelocking member 130 and thetoggle member 120 , thetoggle member 120 will drive thelocking member 130 to move when moving. Wherein, theelastic member 160 is based on its own elastic characteristics, and it will apply a pre-tightening force to thetoggle member 120 in the state of energy storage, and thetoggle member 120 will be driven or have a moving tendency under the action of the pre-tightening force, so that the dial Themovable member 120 is movable in a direction opposite to the pressing direction of the operator.

锁止件130沿牵引轮150的端面一侧延伸至套管140内，而锁止件130随拨动件120沿拨动件120的轴向移动，套管140的侧壁位于锁止件130的移动路径上，因此，在弹性件160的预紧力的驱动作用下，锁止件130会随拨动件120移动至与套管140抵接的位置。Thelocking piece 130 extends into thecasing 140 along one side of the end face of thetraction wheel 150, and thelocking piece 130 moves along the axial direction of theswitching piece 120 along with thetoggle piece 120. Therefore, under the driving action of the pre-tightening force of theelastic member 160 , thelocking member 130 will move along with thetoggle member 120 to a position where it abuts against thesleeve 140 .

如图5所示，在锁止件130与套管140的侧壁抵接的情况下，在弹性件160施加的预紧力作用下，锁止件130与套管140的侧壁之间会存在较大的摩擦作用，二者之间实现了相互制动，也即锁止件130无法相对于套管140产生相对运动，从而使拨动件120和牵引轮150均被固定，而处于锁止状态。As shown in FIG. 5 , when thelocking member 130 abuts against the side wall of thesleeve 140 , under the pretightening force exerted by theelastic member 160 , there will be a gap between thelocking member 130 and the side wall of thesleeve 140 . There is a large friction effect, and the mutual braking is realized between the two, that is, thelocking member 130 cannot produce relative movement with respect to thesleeve 140, so that thedriving member 120 and thetraction wheel 150 are fixed, and are in the locked state. stop state.

如图6所示，在需要对主动弯曲段进行弯曲控制时，操作者可通过按压拨动件120而使拨动件120沿轴向移动而带动锁止件130移动，直至锁止件130与套管140分离，二者之间不存在能够阻止相对运动的摩擦阻力，操作者即可通过驱动拨动件120而带动牵引轮150转动，从而经由牵引绳190实现对主动弯曲段的弯曲控制。As shown in Figure 6, when it is necessary to control the bending of the active bending section, the operator can press thetoggle piece 120 to move thetoggle piece 120 in the axial direction and drive the lockingpiece 130 to move until thelocking piece 130 and Thecasing 140 is separated, and there is no frictional resistance between the two that can prevent relative movement. The operator can drive thetraction wheel 150 to rotate by driving thetoggle 120 , thereby realizing the bending control of the active bending section through thetraction rope 190 .

可见，本申请实施例公开的手柄100在具体使用时，通过对拨动件120的按压操作，即可实现牵引轮150在锁止状态和解锁状态间的切换，而且在将主动弯曲段调节至预设弯曲状态时，解除对拨动件120的按压即可实现牵引轮150的自锁，操作者无需手动维持固定拨动件120，显然有效地简化了内窥镜的操作，优化了操作体验。It can be seen that, when thehandle 100 disclosed in the embodiment of the present application is used in practice, thetraction wheel 150 can be switched between the locked state and the unlocked state by pressing thetoggle member 120, and the active bending section is adjusted to In the preset bending state, the self-locking of thetraction wheel 150 can be realized by releasing the pressing on thetoggle 120, and the operator does not need to manually maintain the fixedtoggle 120, which obviously effectively simplifies the operation of the endoscope and optimizes the operating experience .

其中，锁止件130自牵引轮150的端面一侧延伸出，其利用了牵引轮150端面侧的空间，有利于提升手柄100内部的空间利用率，且不会增大手柄100自身的尺寸。Wherein, the lockingmember 130 extends from the side of the end face of thetraction wheel 150 , which utilizes the space on the end face side of thetraction wheel 150 , which is conducive to improving the space utilization rate inside thehandle 100 without increasing the size of thehandle 100 itself.

套管140设于容置腔111内，其可以与壳体110一体成型，也可成型为单独的构件、并固定设于容置腔111中。Thesleeve 140 is disposed in theaccommodating cavity 111 , and it can be integrally formed with thehousing 110 , or can be formed as a separate component and fixed in theaccommodating cavity 111 .

本申请实施例未限制弹性件160与拨动件120的具体驱动关系，弹性件160可向拨动件120施加作为预紧力的推力，则需要将弹性件160布置为压缩状态时推动拨动件120与套管140相抵接的连接关系；弹性件160可向拨动件120施加作为预紧力的拉力，则需要将弹性件160布置为拉伸状态时牵拉拨动件120与套管140相抵接的连接关系。The embodiment of the present application does not limit the specific driving relationship between theelastic member 160 and thetoggle member 120. Theelastic member 160 can apply a thrust as a pre-tightening force to thetoggle member 120, and it is necessary to push the toggle when theelastic member 160 is arranged in a compressed state. The abutting connection relationship between themember 120 and thesleeve 140; theelastic member 160 can apply a pulling force as a pre-tightening force to thetoggle member 120, and it is necessary to pull thetoggle member 120 and the sleeve when theelastic member 160 is arranged in a stretched state. 140 abutting connections.

如图4～图6所示，本申请实施例的套管140和锁止件130均可设为两组，两组锁止件130和套管140分别设于牵引轮150不同的端面一侧，如此即可在牵引轮150的相对两侧实现自锁效果，由此能够进一步地强化手柄100中关于牵引轮150的自锁性能。As shown in Figures 4 to 6, thebushing 140 and the lockingmember 130 of the embodiment of the present application can be set as two groups, and the two groups of lockingmembers 130 and thebushing 140 are respectively arranged on different end faces of thetraction wheel 150. , so that the self-locking effect can be realized on opposite sides of thetraction wheel 150 , thus the self-locking performance of thehandle 100 with respect to thetraction wheel 150 can be further enhanced.

如图3～图6所示，在本申请的一些实施例中，在套管140的侧壁与锁止件130的周侧壁中，其中一者设有卡接凸起131，另一者设有卡接凹陷141，在锁止件130与套管140抵接的情况下，卡接凸起131与卡接凹陷141卡接配合。As shown in Figures 3 to 6, in some embodiments of the present application, one of the side walls of thesleeve 140 and the surrounding side walls of the lockingmember 130 is provided with a lockingprotrusion 131, and the otherA locking recess 141 is provided, and when the lockingmember 130 abuts against thesleeve 140 , the lockingprotrusion 131 is engaged with thelocking recess 141 .

可以理解，卡接凹陷141为卡接凸起131提供了容置空间，二者卡接配合时卡接凸起131相当于嵌设在卡接凹陷141内部，二者间不仅能够通过摩擦阻力相互制动，还能够通过相互限位而实现制动，该实施例通过卡接配合的方式可进一步地强化锁止件130与套管140件的制动效果，从而进一步地优化牵引轮150的自锁性能。It can be understood that theengaging recess 141 provides an accommodating space for the engagingprotrusion 131, and when the two are engaging and mating, the engagingprotrusion 131 is equivalent to being embedded inside the engagingrecess 141, and the two can not only interact with each other through frictional resistance. Braking can also be achieved by mutual limiting. This embodiment can further strengthen the braking effect of the lockingmember 130 and thesleeve 140 by means of snap fit, thereby further optimizing the self-control of thetraction wheel 150. lock performance.

其中，如图4所示，卡接凸起131设于锁止件130上，卡接凹陷141设于套管140上，当然，卡接凸起131也可设于套管140上，而卡接凹陷141相应设于锁止件130上。本申请实施例对卡接凸起131和卡接凹陷141的具体结构形式也未进行限制，举例来说，卡接凸起131可以为凸点、凸块、凸条等，卡接凹陷141可以为卡槽、卡接孔等。Wherein, as shown in FIG. 4 , the engagingprotrusion 131 is arranged on the lockingmember 130, and theengaging recess 141 is arranged on thesleeve 140. Of course, the engagingprotrusion 131 can also be arranged on thesleeve 140, and the engagingprotrusion 131 can also be arranged on thesleeve 140, while the engaging The connectingrecess 141 is correspondingly provided on the lockingmember 130 . The embodiment of the present application does not limit the specific structural form of the lockingprotrusion 131 and thelocking recess 141. It is a card slot, a card connection hole, etc.

如图4所示，在本申请的一些实施例中，卡接凸起131的侧面设有引导面131a，引导面131a用于引导卡接凸起131滑入卡接凹陷141。可以理解，由于为了确保卡接凸起131和卡接凹陷141在配合时的稳定性，二者的尺寸通常设置得较为接近，这样就使得在装配时难以快速实现对准卡装。对此，本实施例中的卡接凸起131通过设置引导面131a，通过引导面131a引导卡接凸起131滑入到卡接凹陷141中，从而使得卡接凸起131快速地与卡接凹陷141实现组配，以确保手柄100在使用中锁止件130能够顺利与套管140卡接而实现牵引轮150的自锁功能。As shown in FIG. 4 , in some embodiments of the present application, aguide surface 131 a is provided on the side of the lockingprotrusion 131 , and the guidingsurface 131 a is used to guide the lockingprotrusion 131 to slide into thelocking recess 141 . It can be understood that, in order to ensure the stability of the lockingprotrusion 131 and thelocking recess 141 when mating, the dimensions of the two are generally set relatively close, which makes it difficult to quickly achieve alignment and locking during assembly. In this regard, the lockingprotrusion 131 in this embodiment is provided with aguide surface 131a, and the guidingsurface 131a guides the lockingprotrusion 131 to slide into thelocking recess 141, so that the lockingprotrusion 131 quickly engages with the locking Therecess 141 is assembled to ensure that the lockingmember 130 can be smoothly engaged with thebushing 140 to realize the self-locking function of thetraction wheel 150 when thehandle 100 is in use.

其中，引导面131a可以为导向斜面(如图4所示)、导向弧面等类型。Wherein, the guidingsurface 131a may be a guiding inclined surface (as shown in FIG. 4 ), a guiding curved surface and the like.

如图4～图6所示，在本申请的一些实施例中，弹性件160设于第一容置空间151a内，弹性件160的两端分别与拨动件120和牵引轮150相连，并用于向拨动件120施加预紧推力。As shown in Figures 4 to 6, in some embodiments of the present application, theelastic member 160 is arranged in the firstaccommodating space 151a, and the two ends of theelastic member 160 are respectively connected with thetoggle member 120 and thetraction wheel 150, and are used In order to apply a preload thrust to thetoggle member 120 .

在此种结构布局下，弹性件160设于牵引轮150内，其相当于复用了牵引轮150内部的空间，相较于将弹性件160设于容置腔111的方案而无需占据手柄100内部的布局空间，由此能够提升优化手柄100内部的结构布局，并提升结构紧凑性。其中，弹性件160的两端分别与拨动件120和牵引轮150的内壁相连，由于其是通过压缩储能而施加预紧推力，其可以与拨动件120和牵引轮150的内壁之间为固接关系，也可以为抵接关系。Under such a structural layout, theelastic member 160 is arranged in thetraction wheel 150, which is equivalent to reusing the space inside thetraction wheel 150, compared with the scheme in which theelastic member 160 is arranged in theaccommodating cavity 111 without occupying thehandle 100 The internal layout space can improve and optimize the internal structural layout of thehandle 100 and improve the compactness of the structure. Wherein, the two ends of theelastic member 160 are connected with the inner wall of the drivingmember 120 and thetraction wheel 150 respectively, since it applies a preloading thrust by compressing energy storage, it can be connected with the inner wall of the drivingmember 120 and thetraction wheel 150 It is a fixed relationship, and it can also be an abutment relationship.

同时，由于弹性件160设于第一容置空间151a内，第一容置空间151a的内壁可对弹性件160起到约束引导作用，其能够防止弹性件160发生偏斜、扭转等情况，从而确保了弹性件160沿预设方向对拨动件120施加预紧推力。At the same time, since theelastic member 160 is arranged in thefirst accommodation space 151a, the inner wall of thefirst accommodation space 151a can play a role of constraining and guiding theelastic member 160, which can prevent theelastic member 160 from being deflected, twisted, etc., thereby It is ensured that theelastic member 160 exerts a pretightening thrust on thetoggle member 120 along a preset direction.

如图3～图6所示，在本申请的一些实施例中，牵引轮150包括轮本体151以及设于轮本体151的端面的转轴152，轮本体151开设有第一容置空间151a，转轴152与套管140转动配合；转轴152具有沿轴向开设的第二容置空间152a，锁止件130经由第二容置空间152a延伸至套管140内。As shown in Figures 3 to 6, in some embodiments of the present application, thetraction wheel 150 includes awheel body 151 and arotating shaft 152 disposed on the end surface of thewheel body 151, thewheel body 151 is provided with a firstaccommodating space 151a, and therotating shaft 152 is rotatably matched with thebushing 140; therotating shaft 152 has a secondaccommodating space 152a opened in the axial direction, and the lockingmember 130 extends into thebushing 140 through the secondaccommodating space 152a.

具体而言，在此种结构布局下，锁止件130位于转轴152中，其复用了转轴152的内部空间，相较于将锁止件130设于容置腔111的方案而无需占据手柄100内的布局空间，这样能够优化手柄100内部的结构布局，并提升结构紧凑性。同时，此种结构布局下的套管140不仅作为轴承结构为转轴152提供了支撑基础，其具备与锁止件130相互制动的作用，可见，该实施例中的套管140也具备一物多用的功能，这样能够对手柄100内部的结构布局起到一定的优化作用，还能够降低生产成本。Specifically, under this structural layout, the lockingmember 130 is located in therotating shaft 152, which reuses the inner space of therotating shaft 152, compared with the solution of setting the lockingmember 130 in theaccommodating cavity 111 without occupying the handle. The layout space within thehandle 100 can optimize the structural layout inside thehandle 100 and improve the compactness of the structure. At the same time, thebushing 140 under this structural layout not only serves as a bearing structure to provide a support base for therotating shaft 152, but also has the function of mutual braking with the lockingmember 130. It can be seen that thebushing 140 in this embodiment also has a The multi-purpose function can optimize the structural layout inside thehandle 100 to a certain extent, and can also reduce the production cost.

当然，锁止件130可以自轮本体151的端面穿设出而设置在转轴152之外的区域，如此情况下，牵引轮150可在端面开设第二避让口151b，用以供锁止件130通过，为了配合拨动件120的移动，第二避让口151b根据拨动件120的移动路径延伸布置。Certainly, the lockingmember 130 can pass through the end surface of thewheel body 151 and be arranged outside the area of therotating shaft 152. Through, in order to cooperate with the movement of thetoggle member 120 , the second avoidance opening 151 b is extended and arranged according to the movement path of thetoggle member 120 .

其中，锁止件130和拨动件120可以一体成型，它们能够通过上述实施例实现快捷装配。当然，锁止件130和拨动件120也可以分别为独立的构件，锁止件130可以在拨动件120在第一容置空间151a中安装到位后再与拨动件120连接，例如，如图4所示，在牵引轮150包括转轴152以及转轴152具有第二容置空间152a的实施例中，锁止件130可以经由第二容置空间152a的开口伸入转轴152内并与拨动件120的侧面连接，具体可通过卡接、螺纹连接等方式实现连接，同时，该实施例中，牵引轮150的端面以及转轴152的侧壁不需要开设第二避让口151b和第三避让口152b，这样可提升牵引轮150整体的结构强度。Wherein, the lockingmember 130 and thetoggle member 120 can be integrally formed, and they can be quickly assembled through the above-mentioned embodiments. Of course, thelocking piece 130 and thetoggle piece 120 may also be independent components, and thelocking piece 130 may be connected to thetoggle piece 120 after thetoggle piece 120 is installed in place in the firstaccommodating space 151a, for example, As shown in FIG. 4 , in an embodiment where thetraction wheel 150 includes arotating shaft 152 and therotating shaft 152 has a secondaccommodating space 152a, the lockingmember 130 can extend into therotating shaft 152 through the opening of the secondaccommodating space 152a and communicate with the dial. The side connection of themovable member 120 can be specifically connected by clamping, threaded connection, etc. At the same time, in this embodiment, the end surface of thetraction wheel 150 and the side wall of therotating shaft 152 do not need to open thesecond avoidance port 151b and the third avoidance port. Theopening 152b can improve the structural strength of thetraction wheel 150 as a whole.

如图3～图6所示，在本申请的一些实施例中，手柄100还包括轴瓦170，轴瓦170设于套管140与转轴152之间，且轴瓦170套设于转轴152。如此布局下，轴瓦170可在套管140与转轴152之间提供支撑作用，避免套管140和转轴152出现直接磨损，从而延长使用寿命。As shown in FIGS. 3-6 , in some embodiments of the present application, thehandle 100 further includes abearing bush 170 disposed between thesleeve 140 and therotating shaft 152 , and thebearing bush 170 is sleeved on therotating shaft 152 . With such an arrangement, the bearingbush 170 can provide support between thesleeve 140 and therotating shaft 152 , avoiding direct abrasion of thesleeve 140 and therotating shaft 152 , thereby prolonging the service life.

其中，轴瓦170可开设有油槽，通过输出润滑油而形成油膜，以进一步地优化套管140和转轴152在相对转动时的顺畅度。Wherein, the bearingbush 170 may be provided with an oil groove to form an oil film by outputting lubricating oil, so as to further optimize the smoothness of the relative rotation between thesleeve 140 and therotating shaft 152 .

在本申请的转轴152具有第三避让口152b的实施例中，轴瓦170可对应第三避让口152b设置，如此，轴瓦170不仅能够在套管140与转轴152之间起到支撑作用，且还能够与锁止件130限位配合，从而防止锁止件130从转轴152中脱离。In the embodiment of the present application where therotating shaft 152 has the third escape opening 152b, the bearingbush 170 can be arranged corresponding to the third avoidingopening 152b, so that the bearingbush 170 can not only play a supporting role between thesleeve 140 and therotating shaft 152, but also It can limitly cooperate with the lockingmember 130 , so as to prevent the lockingmember 130 from detaching from therotating shaft 152 .

进一步地，轴瓦170可以为轴套，轴套可沿整个周向套设在转轴152上，其与转轴152的组配可靠性更优。Further, the bearingbush 170 can be a bushing, and the bushing can be sleeved on therotating shaft 152 along the entire circumference, and the reliability of its combination with therotating shaft 152 is better.

如图3～图6所示，在本申请的一些实施例中，牵引轮150还包括与轮本体151连接的护套管部153，护套管部153与第一容置空间151a连通，手柄100包括壳体110，护套管部153延伸至壳体110外，第二避让口151b延伸至护套管部153的开口处。As shown in Figures 3 to 6, in some embodiments of the present application, thetraction wheel 150 further includes asheath pipe portion 153 connected to thewheel body 151, thesheath pipe portion 153 communicates with the firstaccommodating space 151a, and thehandle 100 includes ahousing 110 , thesheath tube portion 153 extends out of thehousing 110 , and thesecond avoidance port 151b extends to the opening of thesheath tube portion 153 .

可以理解，拨动件120需要自牵引轮150处延伸至壳体110外部，以供操作者进行操控，而操作者常操控拨动件120的自由端，即远离牵引轮150的一端，如此情况下，拨动件120的受力点与其和轮本体151抵接的区域(位于第一容置空间151a的开口处)的距离较大，从而存在较大的力矩，这样会导致拨动件120与牵引轮150相互间挤压受损的问题。对此，该实施例基于护套管部153的设置，护套管部153可对拨动件120自第一容置空间151a延伸至壳体110外的部分进行包覆，如此可增大拨动件120与牵引轮150的接触面积，从而减弱相互的压强，降低了二者间出现挤压破坏的风险；同时，相较于轮本体151在第一容置空间151a的开口处的部分，护套管部153的顶端与拨动件120的自由端的间距更小，这样形成的力矩较小，也能够进一步地降低拨动件120与牵引轮150相互间挤压受损的风险。It can be understood that the drivingmember 120 needs to extend from thetraction wheel 150 to the outside of thehousing 110 for the operator to manipulate, and the operator often manipulates the free end of the drivingmember 120, that is, the end away from thetraction wheel 150, in this case Next, the distance between the stress point of thetoggle member 120 and the area where it abuts against the wheel body 151 (at the opening of the firstaccommodating space 151a) is relatively large, so there is a relatively large moment, which will cause thetoggle member 120 to The problem of crushing damage to each other with thetraction wheel 150. In this regard, this embodiment is based on the arrangement of thesheath tube portion 153. Thesheath tube portion 153 can cover the part of thedial 120 extending from the firstaccommodating space 151a to the outside of thehousing 110, so that the dial can be enlarged. The contact area between themovable member 120 and thetraction wheel 150, thereby weakening the mutual pressure, reduces the risk of extrusion damage between the two; at the same time, compared with the part of thewheel body 151 at the opening of thefirst accommodation space 151a, The distance between the top end of thesheath tube portion 153 and the free end of the drivingmember 120 is smaller, so that the moment formed is smaller, and the risk of crushing damage between the drivingmember 120 and thetraction wheel 150 can be further reduced.

如图3～图6所示，在本申请的一些实施例中，手柄100还包括环箍180，环箍180套设于护套管部153。可以理解，环箍180可对护套管部153进行束紧，在操控拨动件120的情况下，拨动件120会与护套管部153产生相对挤压，环箍180能够防止护套管部153被挤压变形，对护套管部153起到保护作用。同时，正是由于环箍180对护套管部153的束紧作用，其能够确保护套管部153与拨动件120紧密贴合，避免二者间出现晃动磕碰。As shown in FIGS. 3 to 6 , in some embodiments of the present application, thehandle 100 further includes ahoop 180 , and thehoop 180 is sleeved on thesheath tube 153 . It can be understood that thehoop 180 can tighten thesheath tube 153, and when thetoggle 120 is manipulated, thetoggle 120 will be relatively squeezed against thesheath tube 153, and thehoop 180 can prevent the sheath from Thetube part 153 is extruded and deformed to protect thesheath tube part 153 . At the same time, it is precisely because of the tightening effect of thehoop 180 on thesheath tube portion 153 that it can ensure that thesheath tube portion 153 and thetoggle member 120 are closely attached to avoid shaking and bumping between the two.

如图3所示，环箍180可以设为多个，其中包括与轮本体151邻近设置的环箍180，以及靠近护套管部153的开口设置的环箍180，如此能够优化对护套管部153的束紧效果。As shown in FIG. 3 ,multiple hoops 180 can be provided, including thehoop 180 arranged adjacent to thewheel body 151 and thehoop 180 arranged close to the opening of thesheath tube portion 153, so that the protection of the sheath tube can be optimized.
