DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 It comprises a hub body 1 and a sleeve 2 located at one end of the hub body 1, a plurality of limit parts 3 are arranged on the outer ring of the sleeve 2, one side of the limit part 3 is arranged in an arc shape, and slots 4 for the limit part 3 to pass through are opened at the position of the limit part 3, a front sliding part 5 for driving the limit part 3 to slide up and down is arranged at the lower end of the limit part 3, and an elastic element 6 that can be elastically reset is connected to the lower end of the front sliding part 5;

[0019] The front sliding portion 5 is provided with a groove 7 with one end inclined upward, and the sleeve 2 is also provided with a rotating shaft 8 that can rotate axially, and the rotating shaft 8 is provided with a front protrusion 9, and the front protrusion 9 is provided with a matching portion 10 that matches with the groove 7;

[0020] The hub body 1 is provided with a plurality of openings 11 arranged in a ring shape. A rear sliding portion 12 that can slide up and down is provided in the opening 11 , and a limiting block 13 for limiting is provided at the top of the rear sliding portion 12 .

[0021] The rear sliding portion 12 is provided with a groove 7 of the same shape as the front sliding portion 5, a rear protrusion 14 of the same shape as the front protrusion 9 is provided next to the rear sliding portion 12, a connecting beam 15 for connection is provided between the front protrusion 9 and the rear protrusion 14, and a matching portion 10 for matching the groove 7 is also provided on the rear protrusion 14. A mounting plate 16 for fixed support is provided below the rear sliding portion 12, and an elastic element 6 is provided between the mounting plate 16 and the rear sliding portion 12.
