A servo motor 5 is fixedly connected to one side of the bracket 3. The servo motor 5 can drive the screw rod 4 to rotate. The output end of the servo motor 5 is fixedly connected to the screw rod 4. A screw sleeve 6 is provided on the rod body of the screw rod 4. When the screw rod 4 rotates, the screw sleeve 6 can be moved on the rod body of the screw rod 4, so that the position between the lower pressure seat 9 and the upper pressure block 11 and the grinding wheel machine body 2 can be adjusted.

[0022] Reference Figure 2 The upper end of the screw sleeve 6 is fixedly connected to a mounting plate 7, which can move with the screw sleeve 6.
