[0029] A limiting structure is arranged on the top of the support plate 1, and is used to limit the direction of the clamping structure.

[0030] Furthermore, the limiting structure includes a first disc 5, an arc groove 6, a limiting rod 7, a second disc 15 and a third connecting shaft 19. The first disc 5 is fixedly connected to the top of the support plate 1. The first disc 5 is provided with an arc groove 6. Three groups of limiting rods 7 are fixedly connected to the inner wall of the arc groove 6. The inner wall of the arc groove 6 is movably connected to the second disc 15, and the second disc 15 is in a circular ring shape. Three groups of third connecting shafts 19 are fixedly connected to the outer side of the second disc 15. The three groups of limiting rods 7 serve to limit the movement range of the second connecting shaft 18.

[0031] Furthermore, one end of the three groups of limiting rods 7 is fixedly connected to a connecting disk 13 , the top of the connecting disk 13 is fixedly connected to an auxiliary disk 14 , and the outer side of the auxiliary disk 14 is clamped together with the second disk 15 .

[0032] Furthermore, three groups of connecting blocks 16 are fixedly connected to the top of the second disc 15, and a handle 20 is fixedly connected to the outer side of one group of connecting blocks 16. A third disc 17 is fixedly connected to the top of the connecting block 16, and the third disc 17 is in a circular ring shape. The third disc 17 is clamped together with the outer side of the hub unit component 4. When in use, the hub 4 is sleeved on the third disc 17, and the second disc 15 and the third disc 17 are rotated by rotating the handle 20. The connecting block 16 serves to connect the second disc 15 and the third disc 17.

[0033] Furthermore, the clamping structure includes a clamping block 8, a fixed block 9, a connecting rod 10, a clamping ring 11 and a first connecting shaft 12. The clamping ring 11 is movably connected between the second disc 15 and the third disc 17. The outer side of the clamping ring 11 is fixedly connected to the connecting rod 10.

When the third disc 17 moves, it drives the first connecting shaft 12 to move synchronously, so that the clamping ring 11 swings, and the swing amplitude is limited between the two sets of connecting blocks 16, so as to achieve the clamping of the wheel hubs 4 with different diameters, and the movement of the clamping ring 11 drives the connecting rod 10 to move. The connecting rod 10 plays a connecting role. The connecting rod 10 is connected to the block 8 through the fixing block 9, so that the connecting rod 10 slides on the block 8. When the clamping ring 11 rotates, the second connecting shaft 18 at the bottom of the clamping ring 11 plays a connecting role. The third connecting shaft 19 penetrates the second disc 15 and extends to the arc groove 6, so that the second disc 15 is clamped by the arc groove 6 on the first disc 5, so that the second disc 15 can only rotate. The three sets of limiting rods 7 play a role in limiting the movement range of the second connecting shaft 18.
