[0038] When it is necessary to brake and fix the wheel hub 11 and the wheel body 4, the relevant personnel hold the rotating handle 21 and rotate it on the threaded rod 22, the rotating handle 21 pushes the T-shaped brake plate 20 to move close to the wheel body 4 and the wheel hub 11, the T-shaped brake plate 20 drives the second movable cavity 44 to move, the second movable cavity 44 extrudes the brake rod 23 to deform, and the limiting sliding rod 26 moves in the movable limiting slot 59 on the T-shaped brake plate 20 to stabilize the position of the T-shaped brake plate 20. Then, the T-shaped brake plate 20 is extruded to the wheel hub 11 with the wheel body 4, so as to achieve the braking effect on the wheel hub 11 and the wheel body 4.

[0039] When it is necessary to release the wheel hub 11 and the wheel body 4, the relevant personnel hold the rotating handle 21 and rotate it in the opposite direction on the threaded rod 22, the threaded rod 22 moves away from the wheel hub 11 and the wheel body 4, and then the elastic potential energy of the first return spring 24 drives the T-shaped brake plate 20 to move away from the wheel hub 11 and the wheel body 4, so as to release the wheel hub 11 and the wheel body 4.
