[0002] The steering gear, also known as the steering machine or automobile steering gear, is the most important component in the automobile steering system. During the manufacturing process of the steering gear, the gear clearance of the steering gear needs to be adjusted to achieve the ideal state.

[0003] At present, most factories usually handle the adjustment and testing processes of steering machines separately. After completing the adjustment of the entire batch of steering machines, they will test the entire batch of steering machines. However, when it is found that the steering machine is not adjusted properly during the testing process, it needs to be taken to the adjustment station for re-fixation, positioning, and re-adjustment. This working method is relatively cumbersome. Therefore, further improvements can be made. Summary of the invention
