[0027] During specific use, when it is necessary to fix wheel hubs of different specifications, use the tool clamp hexagonal screw 6 and rotate it to drive the bidirectional threaded shaft 5 to rotate. While the bidirectional threaded shaft 5 rotates, the first clamping seat 8 and the second clamping seat 9 can be slid and adjusted using the slide rod 7.

[0028] In this embodiment, the upper surfaces of the first clamping seat 8 and the second clamping seat 9 are both fixedly connected to the limiting block 10 , and the outer surface of the limiting block 10 is provided with a groove 11 .

[0029] During specific use, the setting of the limit block 10 can be used to fix the wheel hub when the first clamping seat 8 and the second clamping seat 9 are adjusted.

[0030] In this embodiment, a vertical rod 12 is fixedly connected to one side of the inner wall of the groove 11 , and an auxiliary wheel 13 is rotatably connected to the outer surface of the vertical rod 12 .

[0031] During specific use, the setting of the vertical rod 12 can support the auxiliary wheel 13. When rotating, the wheel hub can utilize the setting of the auxiliary wheel 13 to achieve the purpose of rotation.

[0032] In this embodiment, the rotating mechanism 4 includes a support frame 14 , a hydraulic cylinder 15 is fixedly connected to the upper surface of the support frame 14 , and a hydraulic rod 16 is fixedly connected to the output end of the hydraulic cylinder 15 .

[0033] During specific use, when the wheel hub needs to be clamped, the hydraulic cylinder 15 is started to control the hydraulic rod 16 to extend and retract, while pushing the turntable 19 downward to reach a suitable position, thereby facilitating the fixing of the wheel hub.
