Embodiment Construction
[0043] Such as Figure 1 to Figure 10 As shown, the detent 3 includes a pin body 31, a head 32 and a spacer 33, wherein the pin body 31 is conical, the spacer 33 is a right-angled trapezoid, and the pin body 31 is provided with a shape corresponding to the spacer 33. Compatible limit hole 311, the limit piece 33 can be partially inserted in the limit hole 311 and the maximum width of the limit piece 33 is greater than the maximum aperture of the limit hole 311, the limit piece 33 can be inserted from one end of the limit hole 311 Enter and exit. Specifically, the limiting piece 33 is an arc-shaped bent plate with a wide upper end and a narrow lower end, and the limiting hole 311 is also arc-shaped matching it. The narrow end of the arc-shaped bent plate is inserted downward into the limit hole 311, and the part inserted into the limit hole 311 on the limit piece 33 fits with the hole wall of the limit hole 311. At the same time, because the maximum width of the limit piece 33...
