[0003] However, this traditional dismounting method has significant defects. The internal structure of the steering gear is precise and complex, and the stator and the screw rod bearing are installed compactly and have special positions. When using the crowbar and other tools, it is difficult to apply force accurately, not only a lot of manpower and time are consumed, but also the stator and the screw rod bearing are easily damaged irreversibly due to uneven force in the process of knocking and prying, such as causing the deformation of the stator and the breakage of the screw rod bearing ball, thereby affecting the overall performance and service life of the steering gear. At the same time, the manual operation cannot guarantee the standardization and consistency of each dismounting, so that the installation accuracy cannot be effectively guaranteed, which directly relates to the steering control performance and driving safety of the vehicle.

[0004] In recent years, the automobile industry has developed rapidly, and higher standards for the production efficiency and maintenance quality of the steering gear have been put forward.
