If the wheel hub is thicker, the limit plate 2 10 can be pulled to move the extension block 9 outward, thereby adjusting the position of the limit plate 2 10, and then the fixing screw 11 is rotated to move the positioning plate 12 inward to limit the groove on the surface of the wheel hub, thereby limiting the wheel hub. The utility model has a simple structure and can be used for wheels of different sizes and thicknesses, thereby improving the practicality of the wheel hub fixture and facilitating use by staff.

[0029] The second implementation method:

[0030] Based on the first embodiment, this embodiment adds an electric push rod 21, and the rest of the parts are consistent with the first embodiment.
