[0025] Example 2

Compared with the first embodiment, the present embodiment further includes a motor 11, which is connected to the fixing seat 10 by bolts, and the output end of the motor 11 is fixedly connected to a spline shaft 12, and the spline shaft 12 is connected to a grinding sheet 14 through a spline sleeve 13. The spline sleeve 13 is provided with a bearing 15 as a safety fixing sleeve, and one side of the bearing 15 is fixedly connected to a connecting rod 16, and one end of the connecting rod 16 is rotatably connected to a threaded rod 17, and the threaded rod 17 penetrates the mounting frame. 1, the outer ring movable sleeve of the spline sleeve 13 is provided with a sliding sleeve 18 and a protective cover 19, the sliding sleeve 18 is fixedly installed on the top of the protective cover 19, and the side wall of the sliding sleeve 18 is fixedly connected with a connecting rod 20, one end of the connecting rod 20 is rotatably connected with a threaded rod 21, the threaded rod 21 passes through the top of the mounting frame 1, and a sliding groove is provided on the top outer wall of the mounting frame 1, and the sliding groove is connected to a moving frame 22 through a slider 23.

[0027] In this embodiment, threaded rod 1 17 and threaded rod 21 cooperate with the threads of the movable frame 22 so that when they rotate, they can drive the structures connected thereto to move up and down respectively. When the bearing 15 drives the spline sleeve 13 to move on the outer ring of the spline shaft 12, the rotation of the grinding sheet 14 will not be interrupted. At the same time, the sliding sleeve 18 needs to drive the protective cover 19 to always cover the top of the grinding sheet 14 so that the debris generated by grinding will not splash everywhere.

When the height of the grinding sheet 14 needs to be adjusted, the threaded rod 17 is rotated, and through the cooperation with the threaded hole of the movable frame 22, the spline sleeve 13 and the grinding sheet 14 will be driven to rise and fall together through the connecting rod 16 and the bearing 15. After adjusting the height of the grinding sheet 14, the threaded rod 21 is rotated, and through the cooperation with the threaded hole of the movable frame 22, the protective cover 19 will be driven to rise and fall together through the connecting rod 20 and the sliding sleeve 18.
