The traditional baffle ball hinge assembly of Liugong motor accessories is composed of welded joints, ball bowl, clip ring, ball pin and dust cover. The ball bowl is set in the ball seat, the ball head of the ball pin is embedded in the ball bowl, the clip ring is stuck on the opening of the welding joint, and the dust cover is set on the clip ring to prevent dust. Although the traditional ball hinge assembly without baffle is simple in structure, but because the ball pin and welding joint can be rotated relatively, the assembly is usually used in the assembly of welding for fixing, welding method is low efficiency, operation is also more complex.

In addition, the ball bowl is an integral part, which can completely wrap the ball head. However, the ball bowl is not in perfect fit with the welded joints, which will easily lead to uneven forces on the ball head, position deviation and other conditions affecting the use effect of the ball hinge assembly.
