As shown in fig. 1, the ball head locking device provided by the invention comprises a bearing structure, a ball socket 2 and a radial position adjusting mechanism; the ball socket 2 and the radial position adjusting mechanism are both arranged on the bearing structure; an object containing groove is formed in the ball socket 2, and a butt joint space is formed in the object containing groove. One or more adjusting holes 15 are formed in the ball socket 2, and the butt joint space is communicated with the external space through the adjusting holes 15; the radial position adjusting mechanism is arranged in the adjusting hole 15 in a penetrating mode. Bearing structure is last to be provided with reducing guide rail 5, and reducing guide rail 5 contains reducing boss 16, and reducing boss 16 contains gear portion 17, contains free gear 31, prevents escaping gear 32 and locking gear 33 in a plurality of gear portions 17. In the two ends of the radial position adjusting mechanism along the axial direction, one end of the radial position adjusting mechanism is slidably mounted on the reducing boss 16, and the other end of the radial position adjusting mechanism slides along the radial direction of the ball socket 2 to reach the butt joint space.

As shown in fig. 9, the free shift position 31, the anti-escape shift position 32, and the locking shift position 33 are all arc structures, and have corresponding bending radii of R3, R2, and R1, and have R3> R2> R1. Two adjacent radiuses are transited through two sections of circular arcs, each section of circular arc is tangent to the adjacent radius, and the two sections of circular arcs are also tangent, so that the clamping jaw 11 and the ejector 13 cannot have sudden change of acceleration when the locking state is changed, and meanwhile, the abrasion of the clamping jaw 11 and the reducing boss 16 in the movement process is reduced.

In an embodiment, the handle comprises a foldable handle 10; the bearing structure also comprises a ball socket protective sleeve 4, and the ball socket protective sleeve 4 is fixedly connected with the support table 6; as shown in fig. 7, the ball socket protective sleeve 4 is provided with a handle grip clamp 8, and the foldable handle 10 is folded to reach the proximal end into the handle grip clamp 8. Preferably, the ball socket protection sleeve 4 is provided with an opening for the foldable handle 10 to rotate. Preferably, the arc-shaped guide rail 9 is provided with anti-falling sliding grooves 21 on two end surfaces in the radial direction, and the arc-shaped sliding block 7 is provided with protrusions matched with the anti-falling sliding grooves 21 to prevent the arc-shaped sliding block from falling off in the axial direction during rotation.
The invention also provides an application method of the ball head locking device, which is characterized by comprising the following steps: a free butt joint step: rotating the reducing guide rail 5 to enable the clamping jaws 11 to slide to the free gears 31, and butting the ball head 1 into the butting space of the ball socket 2; and (3) posture adjustment: rotating the reducing guide rail 5 to enable the clamping jaws 11 to slide to the escape-proof gear 32, and adjusting the posture of the ball head 1 in the butt joint space; locking and butt joint: the reducing guide rail 5 is rotated to enable the claw 11 to slide to the locking gear 33, and the relative position between the ball head 1 and the ball socket 2 is fixed.
