The adjusting motor 10 is fixed to the cross bar 15, and the adjusting motor 10 is installed through the cross bar 15 between the guide rail 19 frame 13 and the bevel tooth surface 11. After the adjusting motor 10 is started, the position of the bevel tooth surface 11 changes. The change of the support point causes the angle of the swing frame 14 to change, thereby realizing the tilt adjustment of the screen mounting plate 2; a reflective layer is provided in the light shield 22, which can control the light emission direction of the light emitter 12 and reduce scattered light. The light shield 22 is provided with a socket 23, and a colored light-transmitting sheet is inserted in the socket 23.
