The left and right ends of the threaded rod 4 in the groove 13 are fixedly installed with the guide rods 9, and the two groups of guide rods 9 pass through the slider 5 and are slidably connected thereto. The outer walls of the two groups of guide rods 9 are symmetrically sleeved with the slider 5. A cavity 16 is opened in the fixed seat 11, and the bottom wall of the threaded rod 4 passes through the rectangular block 12 and extends to the cavity 16. The driven bevel gear 7 is sleeved in the cavity 16, and the back side of the driven bevel gear 7 is meshed and connected The active bevel gear 6 is connected to the fixing seat 11, and the active bevel gear 6 passes through the outer wall of the fixing seat 11 and is provided with the first motor 8. In this embodiment, when in use, the supporting box 2 and the display screen 1 can be moved to the target position by the moving device, and then the supporting box 2 is auxiliary supported by the supporting device to ensure the stability of the display screen 1. Then, when the height of the display screen 1 needs to be adjusted, the first motor 8 is started, and the output end of the first motor 8 drives the active bevel gear 6 to rotate, the active bevel gear 6 drives the driven bevel gear 7 to rotate, and the driven bevel gear 7 drives the threaded rod 4 to rotate. Since the threaded rod 4 and the slider 5 are connected by threads, when the threaded rod 4 rotates When the slider 5 moves, the slider 5 will slide on the guide rod 9 according to the direction of the thread. If the threaded rod 4 rotates in the clockwise direction, the slider 5 will rise along the guide rod 9. Conversely, if it rotates in the counterclockwise direction, the slider 5 will fall. When the slider 5 rises or falls, the spring 10 at the corresponding position will be compressed. The spring 10 plays a buffering and stabilizing role in the process of the slider 5 rising and falling, ensuring the smooth movement of the slider 5. The connecting rod 14 connects the slider 5 with the mounting plate 15. The mounting plate 15 is mounted with a display screen 1.
