Since the plug rod 603 on the sleeve 601 is connected and matched with the socket 102, the sleeve 601 will not rotate, and only the damping arm 800 will rotate. When the damping arm 800 is rotated to a suitable position, the clamping plate 802 will cooperate with the clamping slot 602, thereby fixing and limiting the damping arm 800, so that the damping arm 800 is firmly fixed at the adjusted position; then the upper end of one of the side plug plates 700 for fixing the picture can be clamped in the limiting slot 803 above the damping arm 800, and then the side plug plate 700 can be fixed, and the picture page turning screen can also be fixed;

(21) When the angle of the flip screen needs to be adjusted, the manual rotation damping arm 800 can be rotated in the above manner to adjust the angle of the flip screen.

(22) To adjust the different picture flipping screens, crank handle 200 to rotate the polygonal shaft 300 and sleeve 301. The rotation of polygonal shaft 300 will then drive the left fixed round plate 400, the right fixed round plate 500, and the side plug plate 700, allowing the picture flipping screen to turn. The upper end of the side plug plate 700 on one side of the corresponding picture flipping screen is designed to fit securely into limit slot 803.
