Moreover, the first motor 5 will slide on the bracket 4 to change the height of the tool holder. Since the adjustment is carried out by the electric motor, the adjustment accuracy is improved, and the adjustment efficiency is also improved. When using the cleaning brush 27, the fixed plate 25 is fixed to the moving block 24 through the mounting assembly 3, and then the first bolt 26 is rotated to make the first bolt 26 drive the cleaning brush 27 to approach the workbench 1 and make the bristles of the cleaning brush 27 closely fit the workbench 1. Then the second motor 22 is started to make the second motor 22 drive the threaded rod 23 on one side of the placing block 21 to rotate. Then the threaded rod 23 drives the fixed plate 25, and then drives the cleaning brush 27 to move on the surface of the workbench 1 to clean the surface of the workbench 1.
