The grinding head sleeve is used for fixing the grinding head and other devices, so that the devices are isolated from the outside, the operation is better, and the whole mechanism is more compact and tidy. The cylinder 5 is fixed on the back of the thrust seat 1 of the static grinding head 4 of the device, the cylinder 5 comprises a piston 51, and the piston 51 is propped against the middle shaft spiral line 2 through a through hole in the middle of the thrust seat 1. The air cylinder is adopted, so that labor cost can be effectively reduced, and production efficiency is greatly improved.

The center shaft spiral line 2 penetrates through the centers of the cross sections of the driven grinding head 3 and the static grinding head 4, and the driven grinding head 3 and the static grinding head are connected in series; the center is penetrated to better improve the operation efficiency of the mechanism and the aesthetic degree of the whole mechanism. The static grinding head 4 and the center shaft spiral line 2 are tightly fixed together by adopting a headless bolt 43; the movable grinding head 3 is connected with the central shaft spiral line 2 through a convex head bolt 31, one end of the convex head bolt 31 butts against the spiral groove 21 of the central shaft spiral line 2, and the other end is locked with the movable grinding head 3.

When the cylinder 5 acts, the piston 51 of the cylinder 5 drives the middle shaft spiral line 2 to push and then drives the dynamic and static grinding heads 4 to move to one side of the dynamic grinding head 3. Meanwhile, the movable grinding head 3 is locked with the raised head bolt 31, and the other end of the raised head bolt 31 is propped against the spiral groove 21 of the middle shaft spiral line 2, so that the middle shaft spiral line 2 is pushed in, the raised head bolt 31 moves along the spiral groove 21, and the movable grinding head 3 is driven to axially rotate.
