When the inclined plane block 45 is inserted into the card slot 411, the auxiliary plate 43 can be fixed and limited. The outer wall of the inclined plane block 45 is fixedly connected with a handle 410, and the handle 410 can be used to drive the inclined plane block 45 to move, thereby releasing the fixed limit of the auxiliary plate 43 by the inclined plane block 45, and the outer wall of the support box 44 is penetrated by the handle 410 and is slidably connected to the penetration point of the handle 410.

[0026] The cleaning structure 5 comprises: a slide groove 51, a slider 52, and a cleaning brush 53. The outer wall of the housing 2 is provided with a slide groove 51, the outer wall of the auxiliary plate 43 is fixedly connected with the slider 52, the auxiliary plate 43 can only move along the outer wall of the housing 2 due to the limitation of the slider 52, the inner wall of the slide groove 51 is slidably connected with the slider 52, the slide groove 51 plays a fixing role in the moving track of the slider 52, the outer wall of the auxiliary plate 43 is fixedly connected with the cleaning brush 53, the cleaning brush 53 will move with the movement of the auxiliary plate 43, the brush surface of the cleaning brush 53 is in contact with the screen 1, and the cleaning brush 53 will clean the dust on the surface of the screen 1 when it moves.

[0027] Working principle: When the LCD display is not in use, the auxiliary plate 43 can be pulled downward, and the protective cloth 41 will move downward with the movement of the auxiliary plate 43, thereby driving the rotating shaft 48 to rotate. When the auxiliary plate 43 moves to the bottom of the LCD display, the auxiliary plate 43 will squeeze the inclined surface of the inclined surface block 45, so that the inclined surface block 45 squeezes the reset spring 49. When the auxiliary plate 43 continues to move downward until the slot 411 and the inclined surface block 45 are in the same horizontal plane, the inclined surface block 45 will be reset by the elastic force of the reset spring 49, so that the inclined surface block 45 can be inserted into the slot 411, thereby fixing the position of the auxiliary plate 43. At this time, the protective cloth 41 will cover the screen 1, thereby protecting the screen 1 and preventing dust from falling on the surface of the screen 1. At the same time, when the LCD display needs to be used, it is only necessary to move the handle 410 away from the support box 44. At this time, the inclined block 45 will move with the movement of the handle 410, thereby causing the handle 410 to disengage from the slot 411, thereby releasing the fixed limit of the auxiliary plate 43 by the inclined block 45. At this time, the torsion spring 46 will drive the rotating shaft 48 to reset through its own torque, thereby retracting the protective cloth 41, thereby exposing the screen 1 for the convenience of user use.

[0028] At the same time, when the auxiliary plate 43 moves, the slider 52 will slide along the inner wall of the slide groove 51 as the auxiliary plate 43 moves, so that the auxiliary plate 43 slides against the outer wall of the outer shell 2, and when the auxiliary plate 43 moves, the cleaning brush 53 will clean the dust on the outer wall of the screen 1 as the auxiliary plate 43 moves, thereby preventing dust from affecting the user's viewing experience and protecting the screen 1 at the same time.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
