[0011] A further setting of the present utility model is that: convex columns for limiting the automotive wheel hub are installed on the opposite sides of the chassis and the pressing plate.

[0012] By adopting the above technical solution, the convex columns on both sides are inserted into the perforations at the center of the wheel hub, so that the wheel hub can be better positioned and its stability is stronger.

[0013] A further setting of the present utility model is that: a controller is installed on the side of the bracket.

[0014] By adopting the above technical solution, the equipment is controlled by the controller to realize automatic operation and reduce manual labor.
