[0002] Bicycles, also known as bicycles or bikes, are usually two-wheeled small land vehicles. After riding on the bicycle, people use pedals as power, which is a green and environmentally friendly means of transportation. In the current era of increasingly scarce resources and energy and increasingly prominent environmental problems, low-carbon travel provides us with a direction and a way to change. The roundness of the wheel hub rims is tested when the bicycle leaves the factory. Most workers will use visual inspection, but this manual correction is not accurate and is prone to errors, which greatly increases the labor intensity of workers and reduces production efficiency.

[0004] Although the device has a simple structure, low cost, and uses precise measurement and quantitative calculation methods to provide a basis for manual adjustment, and improves the accuracy and efficiency of adjusting the roundness, the above correction device has the following defects during use:

[0005] When the correction device is in operation, although it can improve the accuracy and efficiency of the wheel hub roundness, it is difficult to adjust the wheels of different widths and sizes, which increases the difficulty of the workers' operation and reduces work efficiency.
