The threaded rod 12 is slidably connected with multiple U-shaped blocks 9 respectively, a threaded rod 2 13 is threadedly installed on the adapter block 15, and a handle 1 is fixedly installed on the bottom end of the threaded rod 2 13. The top of the threaded rod 12 is rotatably sleeved with an adapter block 2 14, and a strip block 15 is fixedly installed on the top of the adapter block 2 14. Two concave grooves are provided on the top of the strip block 15, and docking rods are fixedly installed between the inner walls on both sides of the two concave grooves. Two hinged rods 16 are rotatably installed on the strip block 15 through the cooperation of the two concave grooves and the two docking rods.

The threaded rod 13 moves downward, and the display screen 11 will rotate upward, otherwise it will rotate downward. The angle of the display screen 11 can be adjusted by adjusting the threaded rod 13, so that the state presented by the display screen 11 meets the actual needs.

[0030] Compared with the related art, the adjustment mechanism of the LED display screen provided by the utility model has the following beneficial effects:

[0031] In the present invention, the restriction on the vertical rod 4 can be released by pushing the slider 20 downward to drive the circular block 23 to move, and then the direction of the display screen 11 can be adjusted left and right by rotating the vertical rod 4. The subsequent rotation of the threaded rod 13 can generate a driving force for the side panels 8 together with the display screen 11 through the two hinged rods 16, so as to adjust the angle of the display screen 11 and adjust the display screen 11 up and down. The two-wheel operation can complete the adjustment of the display screen 11 more meticulously, so that the display screen 11 can better meet personal needs.
