One side of the lever 12 abuts against the fixed plate 11, causing the lever 12 to drive the conveyor wheel 6 to rotate via the fixed plate 11. The conveyor wheel 6 winds around the conveyor belt 5, and the push block 4 drives the brush 3 downwards via the conveyor belt 5 to abut against the display screen 2. At this time, the spring telescopic rod 14 is compressed and shortened. When the lever 12 abuts against the protrusion of the limiting plate 13, the lever 12 drives the rotating shaft 7 to move along the inside of the limiting cylinder 10. The first spring 9 is compressed and shortened, the lever 12 moves and does not contact the fixed plate 11, and the conveyor wheel 6 rotates in the opposite direction. The movement causes the fixed plate 11 to return to its initial position, while the conveyor wheel 6 and the conveyor belt 5 are untangled.

This process is repeated so that the brush 3 can clean the dust accumulated on the surface of the display screen 2. When the push block 4 moves up and down, the fixed rod 15 drives the toothed plate 18 to move up and down via the push block 4.
