[0031] Base plate 3, the base plate 3 is arranged at the bottom of the protection frame 1, support frames 32 are fixedly installed at both ends of the base plate 3, an extension plate 33 is slidably connected inside the support frame 32, and springs 34 are fixedly installed at both ends of the bottom of the extension plate 33;

[0032] Rotating shaft 4, the rotating shafts 4 are respectively fixedly installed on both sides of the protection frame 1, a side plate 41 is fixedly installed at one end of the rotating shaft 4, a threaded rod 42 is fixedly installed on one side of the side plate 41, and a locking nut 43 is threadedly connected to the outer side of the threaded rod 42. The threaded rod 42 is arranged inside the top of the extension plate 33.

[0033] One side of the cleaning brush 21 is attached to the front of the display component 13, and a limiting plate 23 is fixedly installed at the top of the baffle 22.

[0034] When the baffle 22 drives the skateboard 2 to move downward, it will drive the cleaning brush 21 to slide on the front of the display component 13, thereby cleaning the dust on the used display component 13.

[0035] A damping rod 35 is fixedly installed at the bottom of the extension plate 33, and the bottom of the damping rod 35 is fixedly installed at the bottom of the inner side of the support frame 32.
