[0002] The axle is a system consisting of a wheel and an axle, which can rotate around a common axis. It is equivalent to a lever system with the axis as the fulcrum and the radius as the rod. The axle bracket is a component in the mechanical device used to support and fix the axle. In different application scenarios, the design and function of the axle bracket may be different, but the basic principle is the same, that is, to ensure that the axle can rotate stably while bearing various external loads.

[0003] The existing method of testing the axle is to place the axle on an axle bracket and then move it under the testing equipment for testing. The current axle bracket can only be used to place axles of one size, which is not convenient for adapting to axles of different sizes. The axle fixing effect is poor, which can easily cause the axle to shift, resulting in reduced stability of the axle detection.

[0004] Therefore, it is necessary to design a wheel axle bracket that can clamp the wheel axle to prevent the wheel axle from shifting during the detection process, improve the stability of the wheel axle detection, and adjust the position of the second rotating wheel to facilitate the fixing of wheel axle brackets of different sizes for use with wheel axles of different sizes.
