The sleeve 46 thereby drives the first connecting clamp 43 arranged on the outer surface and the straight rod 44 inside the first connecting clamp 43 to move. At this time, the straight rod 44 drives the second connecting clamp 45 arranged at one end to move. The second connecting clamp 45 can move the slide rod 9 inside the slide groove 48, so that the slide rod 9 drives the grinding stone 3 set at one end to be adjusted. Example

[0051] See also Figure 9 , this utility provides a technical solution:

[0052] Different from the embodiment 1, a ring groove 111 is formed on the outer surface of the sleeve 46. After the sleeve 42 is adjusted on the outer surface of the threaded rod 47, a knob 115 provided on the fixing frame 114 is used to drive a screw rod 116 provided on the end face to move, the screw rod 116 drives the arc-shaped plate 113 provided at the bottom end to move, the arc-shaped plate 113 drives the rubber block 112 provided at the bottom and the arc-shaped plate 113 to clamp the ring groove 111. Thus, when the rotating disc 2 is rapidly rotated and then stopped, the sleeve 42 on the outer surface of the threaded rod 47 will be at risk of rotating under the action of inertia, and the rubber block 112 can improve the friction.
