The two side surfaces of the movable block 4 are slidably connected to the U-shaped inverted plug-in board 5. The arranged movable block 4 provides support for the plug-in board 5. The inner top wall of the plug-in board 5 abuts against the transverse board 2. The arranged transverse board 2 provides further support for the plug-in board 5, thereby achieving the installation and fixation of the LED splicing screen.

[0029] The side of the plug-in board 5 is plugged with a plug-in rod 6 through the through groove, and the side of the plug-in board 5 away from the LED splicing screen is plugged with the plug-in rod 6 through the through groove, which improves the functional structural stability of the mounting bracket. The two end surfaces of the plug-in rod 6 are respectively welded with a rotating block 7 and a threaded rod 8 to realize the synchronous movement of the rotating block 7 and the threaded rod 8, and the radius of the threaded rod 8 is smaller than the radius of the plug-in rod 6, which is convenient for the threaded rod 8 to extend into the interior of the plug-in board 5 first, and the threaded rod 8 is threadedly connected to the movable block 4. A rubber block 9 is fixedly connected to the side of the threaded rod 8 away from the plug-in rod 6, and the end face of the rubber block 9 abuts against the limit rod 3, so that the rubber block 9 abuts against the limit rod 3.
