When the screw rotates, the slider moves on the screw, and the slider drives the card plate to move. In this way, the two card plates are brought closer to each other by rotating the adjusting piece, so that the display screen can be fixed, which improves the convenience of fixing.

[0019] 2. The utility model provides components such as a clamping plate and a snap plate. By pulling the snap plate apart, the snap plate is made level with the card member, and then the display screen is placed inside the card member. Then, under the action of the reset torsion spring, the reset torsion spring drives the snap plate back to its original position, thereby fixing the corners of the display screen. The display screen pushes the clamping plate inside the card member and squeezes the compression spring to bear force. Under the action of the compression spring, the clamping plate can be pushed so that the clamping plate is close to the display screen, thereby being fixed more firmly and increasing stability.
