The positive rotation of the two threaded rods 7 forces the two moving blocks 12 to drive the springs No. 2 14 and No. 3 15 on the tops of the two moving support plates 13 to move to the bottom of the lower pressure plate 2. At this time, the bottom of the lower pressure plate 2 increases the pressure of springs No. 2 14 and No. 3 15. When the lower pressure plate 2 descends and pushes spring No. 1 3, spring No. 2 14 and spring No. 3 15, greater pressure can be applied to the grinding disk at the bottom of the bottom plate 4. On the contrary, the two driving motors 10 drive spring No. 2 14 or spring No. 3 15 to move outward to reduce the support of the bottom of the lower pressure plate 2, thereby reducing the pressure on the grinding disk at the bottom of the bottom plate 4.
