[0026] During use, when the display screen body 1 is idle, the mounting plates 21 on both sides drive the flexible dust cover 2 to slide along the slide rail 11 through the slider 22 and be pulled out from the winding mechanism 3 to dock at the center position of the display screen body 1. The two mounting plates 21 can be adsorbed together by the magnetic attraction of the neodymium magnet, so as to play a role in dust prevention and protection of the display screen body 1. A fiber cloth for wiping the mirror surface is fixedly installed on the side of the mounting plate 21 that contacts the display screen body 1. When it can slide to the center position, the fiber cloth on the mounting plate 21 can wipe and clean the screen panel of the display screen body 1 to wipe off residual fingerprints and dust. The fiber cloth can protect the screen of the display screen body 1 when the mounting plate 21 slides. When it is needed, the two mounting plates 21 are separated, and the flexible dust cover 2 is retracted under the action of the retracting mechanism 3. Automatically reeling up drives the mounting plate 21 to move toward both ends along the slide rail 11. The mounting plate 21 can rotate around the slider 22 via the rotating shaft 211, and then can be fixed in the storage shell 12 by the locking mechanism 4 after rotating at the end, so as to realize the storage of the flexible dust cover 2 and the mounting plate 21. The storage shells 12 on both sides can be integrally designed and formed with the display screen body 1, and a combination of hard metal material and flexible anti-collision material is adopted to protect the four corners of the display screen body 1 to avoid the screen from being broken due to collision. By setting the storage shell 12, the flexible dust cover 2 can be stored in a smaller volume and can protect the display screen body 1. The storage shell 12 is set at both ends of the screen and can also be used for hand-holding, so that the storage system can not only save space, but also can conveniently and quickly store the flexible dust cover 2 and the mounting plate 21, and can weaken their influence on the use of the display screen.

[0027] Specifically, the winding mechanism 3 includes a fixed rod 31 fixedly installed in the storage shell 12, a rotating drum 32 mounted on the fixed rod 31, and a torsion spring 33 arranged between the rotating drum 32 and the fixed rod 31, one end of the torsion spring 33 is fixedly connected to the fixed rod 31, and the other end is fixedly connected to the rotating drum 32; when the mounting plate 21 is released, the torsion spring 33 drives the rotating drum 32 to rotate, so that the flexible dust cover 2 fixedly connected to the rotating drum 32 is wound up.

When the mounting plate 21 slides to the position of the slot 423, the block 42 is reset and the mounting plate 21 is locked under the action of the spring 43. When unlocking is required, just press the mounting rod 44, and the mounting rod 44 drives the tilting block 441 to move downward to squeeze the block 42. The block 42 slides toward the direction of the mounting groove 41 to make way, thereby releasing the lock on the mounting plate 21. After that, the block 42 is pushed to reset while the spring 43 pushes the block 42 to reset.

[0029] Furthermore, a guide block 424 is fixedly mounted on the card block 42, and a guide groove 411 adapted to the guide block 424 is opened on the storage shell 12; when the card block 42 slides, it is limited by the guide block 424 and the guide groove 411, and only performs translational movement without tilting, which can effectively realize the locking and release of the mounting plate 21.
