The movable plate 17 and the movable rod 18 are made as one piece, and the movable plate 17 and the fixed shaft 16 are rotatably connected, so that when the display screen module body 2 is disassembled, the staff can slightly squeeze the display screen module body 2 toward the bracket installation surface body 1 to make the rack 14 slide slightly toward the inside of the installation bin 9. At this time, the movable rod 18 fits the outer peripheral edge of the special-shaped guide groove 13 and slides along the edge. In this process, the movable plate 17 rotates and tilts accordingly, and then moves in the direction close to the bracket installation surface body 1 under the elastic action of the second spring 12 until the movable rod 18 is located in the recessed part of the special-shaped guide groove 13 close to the second spring 12.

In this process, the movable member 20 moves toward the direction close to the bracket mounting surface body 1, and the rack 14 is meshed with the gear 11, so that the two sets of clamping and limiting plates 19 are correspondingly rotated and unfolded to release the clamping restriction on the convex rod 8, and the display screen module body 2 can be further removed from the bracket mounting surface body 1. In this process, the elastic force of the second spring 12 is greater than the elastic force of the first spring 7, so that the above operation can be completed;

[0038] When the display screen module body 2 needs to be reinstalled, align the groove of the movable positioning block 6 on the display screen module body 2 with the magnet block 3 and insert it, and further squeeze the display screen module body 2 toward the bracket mounting surface body 1. During this process, the movable rod 18 slides along the inner wall of the special-shaped guide groove 13 until it enters the recessed part of the special-shaped guide groove 13 away from one end of the second spring 12. Then, under the elastic preload force of the second spring 12, the movable part 20 is fixed at this position. During this process, the convex rod 8 and the leveling screw 15 complete the fitting and extrusion, and the clamping and limiting plate 19 rotates and splices to complete the clamping and limiting of the convex rod 8, completing the installation task of a group of display screen module bodies 2. Multiple groups of display screen module bodies 2 can be spliced ​​and installed in the above manner. During the entire above-mentioned disassembly and installation process, the staff only needs to squeeze the display screen module body 2, and the operation process is convenient and fast.
