[0032] Working principle: When a bicycle wheel hub needs to be fixed and supported, it is placed on the surface of the operating plate 101. Then, with the cooperation of the rotating shaft 150 and the throttle 152, the rotating shaft drives the side gear 140 to rotate. This causes the side gear 140 to transmit power to the screw 131 through the side gear 141. With the support of the slide rod 133, the slider 130 moves, thereby driving the inner support rod 110 to move. The three sets of inner support rods 110 assist in providing auxiliary limiting support for the outer ring of the wheel hub, facilitating the initial support of the wheel hub. During support, it can be raised externally as needed. The shims 112 and washers 113 facilitate supporting the outer ring of the wheel hub at a suitable height from the surface of the operating plate 101. At the same time, the middle rod 1... With the cooperation of 20, the bushing in the center of the wheel hub is also assisted in positioning and support through the middle pad 121, which facilitates the subsequent assembly of corresponding components between the bushing and the center of the wheel hub. Then, the screw pin 154 is tightened to limit and retain it, making subsequent use more convenient. During assembly and use, it is easy to make auxiliary adjustments and rotations as needed. With the cooperation of the ring 160 and the outer sleeve 162, it is easy to rotate the assembly chamber 100 horizontally. Then, with the cooperation of the locking pin 163, it is easy to provide auxiliary limit support. At the same time, with the cooperation of the support head 181 and the ferrule 182, the angle is adjusted. Then, with the cooperation of the pin 183 and the socket 184, the angle adjustment is limited and retained, making subsequent operation and use more convenient. The operation ends here.
