[0027] The utility model is divided into the following steps when used:

[0028] S1: First, find the threaded rod 9 and threaded ring 21 assembly that matches the inner diameter of the wheel hub, then install the threaded ring 21 into the avoidance groove 22, prevent the wheel hub from being placed on the tray 17, align the center of the wheel hub with the center of the avoidance groove 22, insert the threaded rod 9, and rotate the threaded rod 9 until the lower surface of the knob 10 is in close contact with the upper surface of the wheel hub to complete the fixing of the wheel hub;
