[0016] REFERENCE NUMERALS

[0017] Control swing arm 1, hollow shaft 2, guide slope 3, slot 4, anti-back convex surface 5, mounting hole 6, control tab 7, anti-back convex platform 8. DETAILED DESCRIPTION

[0018] In order to better illustrate the content of the utility model, the following will be expanded with the description of the drawings and the implementation examples:

[0019] There are Figures 1-3 As shown in the utility model discloses a kind of limiting piece structure of mechanical clutch transmission shaft, including control swing arm 1, the control swing arm 1 is fixedly connected with the hollow shaft 2 that can be inserted into mounting hole 6, the outer circle side of the end of the hollow shaft 2 away from the control swing arm 1 is provided with at least one anti-back convex surface 5 extending to the outside.

[0020] Further, the hollow shaft 2 is provided with slot 4 for installing control tab 7.

[0021] Further, the end of the hollow shaft 2 away from the control swing arm 1 is provided with at least one anti-back convex platform 8.

[0022] Further, the side of the anti-back convex platform 8 away from the control swing arm 1 is provided with guide slope 3.

[0023] Further, the anti-back convex surface 5 is provided on the anti-back convex platform 8.

[0024] Further, the hollow shaft 2 can be deformed under the extrusion of the guide slope 3.

[0025] Specifically, in use, the control dial 7 is arranged in the mounting hole 6 below the transmission shaft, then the hollow plug shaft 2 is directly inserted into the mounting hole 6 from the rear side, so that the hollow plug shaft 2 is distributed on both sides of the mounting hole 6, and the hollow plug shaft 2 is slightly deformed under the action of the guide slope 3 until the anti-back convex platform 8 passes through the mounting hole 6, at this time the guide slope 3 is no longer extruded by the inner wall of the mounting hole 6, the hollow plug shaft 2 expands outward, so that the anti-back convex platform 8 is buckled at the end of the mounting hole 6, and the anti-back convex surface 5 achieves the locking effect of anti-back;

[0026] When disassembled, the hollow plug shaft 2 and the anti-back convex platform 8 are close to the control dial 7 by extrusion force, then the hollow plug shaft 2 can be directly pulled out, achieving quick installation.

[0027] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the technical solutions of the present application have been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
