Even if the sealing ring is improved, the shearing deformation and damage of the rubber caused by the rotation and extrusion still occur during the installation. In addition, the angle cannot be quickly positioned to the design requirement during the installation due to the lack of limiting, and the rotation loosening caused by subsequent vibration cannot be avoided.

[0003] Therefore, the installation, sealing and anti-loosening of the existing conventional steering pump structure need to be further improved. CONTENT OF THE UTILITY MODEL
