After the rotating disk 2 rotates to adjust the clamping assembly 4 to position the cone, the self-locking function of the worm wheel portion 22 and the worm portion 51 is used to achieve locking and positioning.

[0021] Furthermore, a return spring 43 is wrapped around the positioning shaft 41, and the two ends of the return spring 43 are respectively connected to the side wall of the semicircular head 42 and the side wall of the positioning ring 3. The return spring 43 facilitates the reverse rotation of the rotating disk 2 to move the positioning shaft 41 on the positioning ring 3, and the semicircular head 42 is always tangent to the side wall of the inclined groove 21.
