[0026] It should be noted that the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0027] It should be noted that: similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0028] Please refer to Figures 1-5The universal structure for connecting the hub with external accessories comprises a taper seat screw 1, an amplification and reduction ring 4 sleeved outside the taper seat screw 1, four connecting rods 3 movably connected in an array on the inner side of the amplification and reduction ring 4 and located outside the taper seat screw 1, a plug seat 2 fixed to one end of each connecting rod 3, a taper bottom ring 5 arranged at one end of the amplification and reduction ring 4 close to the plug seat 2, a limiting base 6 arranged at one end of the amplification and reduction ring 4 away from the plug seat 2, and the amplification and reduction ring 4, the taper bottom ring 5 and the limiting base 6 being detachably fixedly connected.

[0029] The end of the plug seat 2 away from the connecting rod 3 is attached to the taper seat screw 1, the end of the plug seat 2 close to the connecting rod 3 is attached to the taper bottom ring 5, the end of the connecting rod 3 away from the plug seat 2 is movably connected to the limiting base 6, the limiting base 6 is provided with a nut 7 at the end thereof away from the amplification and reduction ring 4, the nut 7 is located outside the taper seat screw 1 and is threadedly connected to the taper seat screw 1, the nut 7 is provided with a lock head 8 at the end thereof away from the limiting base 6, and the taper seat screw 1, the amplification and reduction ring 4, the taper bottom ring 5, the limiting base 6, the nut 7 and the lock head 8 are coaxially arranged.

[0030] The lock head 8 is located outside the taper seat screw 1 and is threadedly connected to the taper seat screw 1, and in order to further limit the position of the lock head 8, a screw hole is formed in the inside of the lock head 8 and located outside the taper seat screw 1, and a stop screw 9 is threadedly connected to the inside of the screw hole and threadedly cooperates with the taper seat screw 1.

[0031] Firstly, the taper bottom ring 5 is attached to the plug seat 2, and the taper of the taper bottom ring 5 is used to change the position of the plug seat 2 by cooperating with the rotation of the amplification and reduction ring 4, so that the diameters between the four plug seats 2 are enlarged or reduced, and different hub hole diameters are adapted, so that the hole diameter of the automobile hub is tightly attached and displacement is prevented.

[0032] Then, the hub cover is placed outside the taper seat screw 1, and the limiting base 6, the taper bottom ring 5 and the plug seat 2 are used to produce an outward pulling force when the hub cover is locked, so that the taper seat screw 1 moves outward, and the moving direction of the fixed connecting rod 3 is determined.
