[0016] The present invention is further configured such that a sealing ring that fits against the fixing cover is fixedly sleeved on the top of the mounting base.

[0017] By adopting the above technical solution and setting the sealing ring, the sealing effect between the fixed cover and the mounting base can be improved.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model involves first fitting a dust cover onto the rotating shaft and pushing it inwards. Once the dust cover is fully in place, a screw is used to pass through the mounting hole to fix the mounting base onto the machine body. Then, the front end of the fixing cylinder is grasped and pulled outwards. When the fixing cylinder is stretched to the appropriate position, the throttle is held by hand to rotate the threaded rod. When the threaded rod rotates, it will drive the positioning plate to apply pressure to the corrugated end through the cooperation of the telescopic rod. This can improve the positioning effect of the end connected to the shaft, improve the fixing firmness and stress strength, and ensure the safety of the steering gear.

[0020] 2. The utility model discloses a structure that is simple and convenient to operate, and improves the maintenance and maintenance efficiency of personnel, and is good in flexibility. BRIEF DESCRIPTION OF DRAWINGS
