[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] Example 1
[0031] Please refer to Figure 1-3 As shown, this embodiment provides a pin shaft stopping structure, including a pin shaft 1; the pin shaft 1 is provided with at least two groups of pin holes, one group of pin holes is opened at the center of the pin shaft 1, and the other group of pin holes is opened at one side of the pin shaft 1.
[0032] This solution also includes a first stop sleeve 2 and a second stop sleeve 3:
[0033] The first stop sleeve 2 is provided with a first stop hole 21 , which is rotatably arranged outside the center of the pin shaft 1 , and the first stop sleeve 2 is provided with a hole 22 penetrating the first stop hole 21 .
[0034] The second stop sleeve 3 is arranged in a Y-shaped structure, and a second stop hole 31 is opened on the second stop sleeve 3. The second stop hole 31 is rotatably arranged on the outside of the pin shaft 1, and the second stop sleeve 3 is arranged on the outer periphery of the first stop sleeve 2. A second hole 2 is opened on the second stop sleeve 3 to penetrate the second stop hole 31.
