Example Embodiment
[0038] Example 1
[0039] refer to Figure 1 to Figure 7 , the present invention provides a self-locking device suitable for an endoscope. In the first embodiment of the present invention, its main body includes a connecting component 100 and a matching component 200, and the connecting component 100 and the matching component 200 interact with each other. , to achieve self-locking and non-self-locking states.
[0040] Specifically, the connection assembly 100 includes a driven gear 101 and a toggle lever 102, and the driven gear 101 and the toggle lever 102 are matched by pins 401, so that when the toggle lever 102 moves, the driven gear 101 can achieve relative The left and right movement of the matching component 200 (here "left and right" is relative to the orientation in the figure, for the sake of clarity, the positive direction of the x-axis in the figure is defined as "right", and the following uses "left" or "right" to describe, not Repeatedly), so as to achieve a s...

[0047] Example 2
[0048] refer to Figure 1 to Figure 7 , the present invention provides a self-locking device suitable for an endoscope. In the second embodiment of the present invention, this embodiment is different from the first embodiment in that: in this embodiment, it also includes a fixed The assembly 300 includes a central shaft 301 and a positioning member 302, the driving gear 201 and the driven gear 101 are sequentially sleeved on the central shaft 301, the left limiting member 302 is fixed with the central shaft 301 by bolts, and the paddle 102b is connected by a pin shaft 402 is connected with the positioning member 302 .
[0049] Specifically, the connecting assembly 100 includes a driven gear 101 and a lever 102. The driven gear 101 includes a connecting protrusion 101a. The connecting protrusion 101a is provided with a limit hole 101a-1, and the horizontal direction of the limit hole 101a-1 is The shape of the cross section is a notch shape. The toggle lev...

[0058] Example 3
[0059] refer to Figure 1 to Figure 7 , the present invention provides a self-locking device suitable for an endoscope. In the third embodiment of the present invention, this embodiment is different from the second embodiment in that: in this embodiment, the connecting assembly 100 It also includes a spring sheet 103, which fits with the driven gear 101. The spring sheet 103 is provided with a first protrusion 103a, and the first protrusion 103a cooperates with the pressing protrusion 102a-3 on the gear connecting block 102a.
[0060] In order to facilitate understanding, the direction in the figure is taken as an example to illustrate. When the pressing protrusion 102a-3 is below the first protrusion 103a, the device is in a self-locking state; when the pressing protrusion 102a-3 When the device is above the first protrusion 103a, the device is in a non-self-locking state. Through the mutual cooperation of the pressing protrusions 102a-3 and the first pro...
