[0028] Furthermore, the inner wall of the bottom box 1 is fixedly connected to an empty box 11, and the empty box 11 is fixedly connected to a connecting rod 13 through a spring 12.

[0029] In the specific implementation process, it is worth noting that the material of the spring 12 is carbon spring steel, and the elastic coefficient of the spring 12 is selected according to actual needs to meet the work. After the frame is fixed, the frame is first placed on the support plate 14. At this time, the weight of the frame drives the support plate 14 to descend, and the connecting rod 13 of the support plate 14 moves in the empty box 11.

When grinding is completed, stop the grinding assembly 2, rotate the motor 31 in the opposite direction, and the splints 36 on both sides return to their initial positions. The frame is released, the external vacuum cleaner is stopped, and the staff takes down the grounded frame.

[0034] In the specific implementation process, it is worth noting that the first moving assembly 22 includes a second slide rail and a second slider. The second slide rail is fixedly connected to the surface of the first slider. The second slider is slidably engaged with the surface of the second slide rail. When the second slide rail is activated, the second slider moves on the second slide rail, thereby driving the grinding assembly 2 to move in the left and right directions, thereby increasing the grinding range of the grinding assembly 2.

[0035] Furthermore, the outer wall of the first moving assembly 22 is fixedly connected to a hydraulic cylinder 21. The model of the hydraulic cylinder 21 is selected according to actual needs and can meet the work requirements. The outer wall of the grinding assembly 2 is installed at the output end of the hydraulic cylinder 21.
