And (3) adjusting the left and right back-and-forth movement amplitude of the screen body: the left and right movement amplitude of the screen body can be realized by rotating a hand wheel at the upper end of the vertical screw rod. Rotating a hand wheel at the upper end of the vertical screw clockwise to enable the horizontal support to move downwards and enable the horizontal support to be far away from the rotating axis of the cam, so that the left and right movement amplitude of the cam slider is reduced, because the screen body support frame penetrates through a middle square hole 2-8-2 of the cam slider, the left and right movement amplitude of the screen body support frame is synchronously reduced, and because the screen body support frame is fixed with the screen body, the left and right movement amplitude of the screen body is synchronously reduced; similarly, the handle at the upper end of the vertical screw rod is rotated anticlockwise, so that the horizontal support moves upwards, namely the cam slider is close to the rotating axis of the cam, the left-right movement amplitude of the screen body support frame is increased, and the left-right movement amplitude of the screen body is increased; the adjustment of the left and right back-and-forth movement amplitude of the screen body is realized.
