[0007] Furthermore, a limiting rod can be provided at the center of the inner side of the annular inverted buckle, and a limiting hole is provided on the outer side of the limiting rod, with a spring installed in the limiting hole.

[0008] Furthermore, a damping ball is provided at one end of the spring, a damping disk is provided on the inner side of the rotating ring, and a spherical groove is provided on the side of the damping disk facing the damping ball. The limiting hole can be replaced with an elastic rod.

[0009] Furthermore, a limiting groove is provided on the side of the damping disc away from the spherical groove.

[0010] Furthermore, the ball joint and the rotating ring are connected by the annular groove and the annular buckle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the design of a rotating ring, annular groove, annular inverted buckle, limiting block, curved groove, elastic block, and protruding point, utilizes the elasticity of the plastic itself to reduce the number of parts required for the rotatable connection between the ball head rod and the rotating ring, simplifying the structure and reducing the cost of the ball head base.

[0013] This utility model, through the design of a damping disc, spherical groove, limiting rod, limiting hole, spring, damping ball, mounting base, protrusion, and limiting groove, allows the limiting rod to hold the damping disc in place when the ball head rod is connected to the rotating ring in a damping manner. The damping ball, under the action of the spring, presses against the spherical groove on the damping disc. When the ball head rod rotates, the damping ball rotates along the annular spherical groove, producing a damping effect. The limiting rod and spring ensure the axial stability of the damping effect.
