An electric push rod 12 is fixed to the inner wall of the outer rotating shaft 11. The piston rod of the electric push rod 12 is fixed with an inner rotating shaft 13. The inner rotating shaft 13 at the same side position cooperates with the lead screw 6. A fixed seat 15 is fixedly installed between two fixing plates 9. A rotating seat 16 is rotatably installed on the fixed seat 15. The mounting plate 2 is detachably connected to the rotating seat 16.

[0028] By setting the mounting base 1 and the mounting plate 2 to cooperate with each other, the mounting base 1 is fixed on the wall through the first bolt 3, the mounting plate 2 is connected to the LED screen through the second bolt 4, and the mounting plate 2 realizes the disassembly, connection and locking with the rotating seat 16 through the insertion plate 18 and the plate sleeve 17, thereby realizing the indirect assembly connection between the LED screen and the wall, without directly fixing to the wall through bolts, effectively preventing the problem of thread slipping affecting the stability when the bolts are screwed multiple times. By setting the lead screw 6 to cooperate with the motor 10, the two output shafts of the motor 10 cooperate with the lead screws 6 on both sides. When rotating synchronously on both sides, the horizontal distance of the LED screen is adjusted. When one of the lead screws 6 rotates, the horizontal angle is adjusted, and by using the rotating seat 16 to cooperate with the fixed seat 15, the pitching angle is adjusted, so as to be better applicable to multi-angle use and improve the universality.

[0029] A plurality of limit grooves are provided on the inner wall of the outer rotating shaft 11. A plurality of limit blocks 20 are fixedly installed on the outer surface of the inner rotating shaft 13. The limit blocks 20 are slidably installed on the inner wall of the limit grooves. The limit blocks 20 and the limit grooves cooperate with each other, so that the outer rotating shaft 11 and the inner rotating shaft 13 can rotate synchronously, and the phenomenon that the inner rotating shaft 13 slides out of the outer rotating shaft 11 can be avoided.

[0030] A number of guide rods 19 are fixedly installed between two fixed brackets 5 on the same side. The movable plate 7 is slidably installed on the outer surface of the number of guide rods 19. The guide rods 19 can be used in cooperation to support and limit the movement of the movable plate 7, so that the movable plate 7 is not prone to shaking and tilting during movement.

[0031] A cross socket 14 is fixedly installed at the end of the inner rotating shaft 13. A cross slot is opened at the end of the lead screw 6. The cross socket 14 and the cross slot are used in cooperation. By using the cross socket 14 in cooperation with the cross slot, synchronous rotation can be achieved when the inner rotating shaft 13 is connected to the lead screw 6.

A partition positioning hole for the partition positioning rod 23 to insert is opened on the insertion plate 18. A spring 25 is fixedly installed between the operating rod 24 and the plate sleeve 17. When the insertion plate 18 is inserted into the plate sleeve 17, the elastic force of the spring 25 can be used to drive the partition positioning rod 23 to insert into the partition positioning hole to achieve locking.

[0034] When in use, first use the mounting base 1 and bolts to fix the mounting base 1 on the wall, then use the second bolt 4 to assemble the mounting plate 2 with the LED screen. Then pull the operating rod 24 on the side of the plate sleeve 17 of the rotating seat 16. The operating rod 24 drives the partition positioning rod 23 to move and stretch the spring 25. Then insert the plug board 18 on the side of the mounting plate 2 into the plate sleeve 17 on the rotating seat 16. After insertion, release the operating rod 24. The elasticity of the spring 25 will drive the partition positioning rod 23 to reset and insert into the partition positioning hole, realizing the locking of the rotating seat 16 and the mounting plate 2, and thus completing the installation of the LED screen. When horizontal angle adjustment is required, two lead screws 6 can be rotated synchronously or one lead screw 6 can be rotated. The synchronous rotation of the two lead screws 6 is realized by the synchronous movement of the two electric push rods 12, and the rotation of one lead screw 6 is realized by the operation of one electric push rod 12. When the electric push rod 12 extends, it drives the inner rotating shaft 13 to move. The inner rotating shaft 13 drives the cross socket 14 to insert into the cross slot on the corresponding lead screw 6. Then start the motor 10. The motor 10 drives the outer rotating shaft 11 to drive the inner rotating shaft 13 to rotate, and then drives the lead screw 6 to rotate, thereby driving the movable plate 7 to move, and thus driving the fixed plate 9 to drive the fixed seat 15 to swing through the hinge arm 8, realizing the horizontal angle adjustment. When the pitch angle adjustment is required, unscrew the locking nut 22. At this time, the rotating seat 16 is unlocked and can swing in the pitch direction. After swinging to the required position, screw on the locking nut 22 to lock the position.
