After assembly, the inner cam is erected on the limiting step, the bottom surface of the inner cam abuts against the end face of the arc limiting block, and the side face of the inner cam abuts against the inner wall of the inner support cylinder, so that a limiting effect is achieved.

Preferably, the thickness of the outer collar is substantially greater than the thickness of the inner collar. The inner convex ring is small in thickness, the friction area is reduced, the outer convex ring is large in thickness, and the structural strength is improved.

Preferably, the end face of the rubber bearing where the inner convex ring is located is provided with a layer of sand prevention film. The sand prevention film can prevent the invasion of silt, and there is reasonable clearance to prevent rubbing between stainless steel axle sleeve and the rubber bearing when pivot job stabilization moreover, and only two-layer sand prevention film rubs with the stainless steel axle sleeve, has improved the life of mechanism greatly.

Preferably, the number of the arc-shaped limiting blocks is two, and the number of the corresponding limiting grooves and the corresponding limiting strips is also two.

Preferably, the rubber bearing is made of a urethane rubber material. The material has good ductility, and has excellent wear resistance in the wet friction process of liquid media such as water, oil and the like, even superior to metal materials.

The beneficial effects of the utility model reside in that: 1. can prevent effectively that silt from soaking, guarantee that stainless steel axle sleeve and rubber bearing inner wall have sufficient gap, make the pump shaft operation more steady, improve life.

2. The rubber bearing is made of polyurethane rubber, the material has good ductility, and the wear resistance is excellent in the wet friction process of liquid media such as water, oil and the like, and even superior to that of metal materials.
