[0052] (2) The content to be displayed is placed on the rotating plate 602 in the carrier 601, and then the angle of the camera is adjusted. When adjusting the angle of the side light 605, the rotating plate 602 is rotated. The rotation of the rotating plate 602 can drive the side light 605 to rotate through the connecting seat 603 and the shaft 604. The rotation of the side light 605 drives the L-shaped frame 607 to rotate in the inner cavity of the annular hollow plate 608. The torsion spring 606 can generate a force on the side of the side light 605 away from the rotating plate 602, thereby making the L-shaped frame 607 contact with the concave-convex groove 609. When the L-shaped frame 607 moves to the concave part of the concave-convex groove 609, the L-shaped frame 607 drives the side light 605 to open, thereby increasing the illumination range of the light, otherwise, the illumination range of the light is reduced. With the assistance of the side light 605, the camera can collect the content to be displayed and display it on the multimedia display screen 3, so that it can be displayed; after the display, the multimedia display screen 3 There will be some dust adhered to the surface. The multimedia display screen 3 is moved into the inner cavity of the protective box 1 through the height adjustment mechanism 4. When the multimedia display screen 3 moves to the dust-absorbing cotton 7, the dust on the surface of the multimedia display screen 3 can be wiped by the dust-absorbing cotton 7. In order to facilitate the user to replace the dust-absorbing cotton 7, the maintenance door on the front of the protective box 1 is opened, and the rotating rod is rotated. The rotation of the rotating rod drives the No. 2 active bevel gear 804 to rotate, so that the No. 2 driven bevel gear 803 drives the bidirectional screw 802 to rotate. The rotation of the bidirectional screw 802 makes the movable plates 805 threadedly connected at the upper and lower ends thereof move away from each other. The movement of the movable plate 805 makes the vertical rods 806 at the upper and lower ends drive the two Z-shaped plates 807 to move away from each other, and then the two blocks 808 can move away from each other until the two blocks 808 are moved out of the inner cavity of the two slots 809, the limit on the left and right sides of the dust-absorbing cotton 7 can be released, and then the dust-absorbing cotton 7 can be moved out of the protective box 1 and cleaned or replaced.
