When the moving end of the electric slide 53 moves, it can drive the box body 6 and the sliding shaft 52 to move horizontally along the sliding shaft 52, thereby changing the lateral position of the box body 6 and the structure thereon.
[0031] Preferably, as another embodiment of the utility model, the height adjustment mechanism 9 includes an electric slide 91, a limit rod 92 and a cylindrical block 93. Limit rods 92 are provided on the front and rear sides of the interior of the box body 6. Both ends of the limit rods 92 are connected to the inner wall of the box body 6.

When the moving end of the electric slide 1 53 moves, it can drive the box body 6 and the sliding shaft 52 to move horizontally along the sliding shaft 52, thereby changing the lateral positions of the box body 6, the front motor 27, the grinding disc 82, the rear motor 27 and the brush 81. When grinding, the grinding disc 82 is driven to press against the stone. When cleaning the surface of the stone and the surface of the plate 1, the brush 81 is driven to press against the surface of the stone or the surface of the plate 1. At this time, when the motor 27 drives the grinding disc 82 or the brush 81 to rotate, the overall grinding or scrubbing of the stone surface can be completed. At the same time, when the water source is turned on, water will be passed into the connecting pipe 14 and the circular pipe 12, and the water will be sprayed from the nozzle 13 on the circular pipe 12, and then sprinkled on the stone surface or the surface of the plate 1, so as to complete the overall flushing of the stone surface and / or the surface of the plate 1. After cleaning the surface of the plate 1, the electric push rod 111 is driven to drive the scraper 10 to move downward and press against the surface of the plate 1, and the scraper 10 will change its position with the box 6, thereby hanging the water and dust on the surface to one side, and discharge them into the rectangular box 16 from the leak hole 41.
