[0005] Preferably, the ball head comprises a head portion and a rod portion, and the head portion is spherical.

[0006] Preferably, the groove is provided on the outer wall of the rod.

[0007] Preferably, an inner slot and an outer slot are provided at the top of the spherical shell, and the lower edge of the dust cover is snap-fitted to the outer slot.

[0008] Preferably, a limiting plate is provided in the inner slot, and the limiting plate is provided with a mounting hole, and the mounting hole is located on the upper end surface of the head.

[0009] Preferably, the inner wall surface of the mounting hole matches the outer wall surface of the head.

[0010] Preferably, a single clip is provided on the upper edge of the dust cover, and a double clip is provided on the lower edge of the dust cover.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a groove on the contact surface between the dust cover and the ball head, and adds grease during assembly, which can effectively avoid abnormal noise caused by friction between the dust cover and the ball head body during the swinging of the ball head; after the dust cover is assembled, it is clamped with a single-layer retaining spring, which reduces product costs while ensuring protection against mud and sand compared to the double-layer retaining spring structure currently used.
