[0033] ​Specifically, in the actual use of the fixed support, when the left and right horizontal angle or the pitch angle of the support needs to be adjusted, first, the second motor 24 starts to rotate, driving the horizontal support 10 to rotate, which in turn drives the pitch support 11 to rotate accordingly. The rotation of the pitch support 11 drives the rotation of the LED screen 22. Through this series of closely connected and coordinated actions, the left and right horizontal angle adjustment of the device is completed. Subsequently, the first motor 6 rotates at a constant speed, thereby driving the worm 8 to start rotating. The rotation of the worm 8 drives the rotation of the worm gear 9, which in turn drives the rotation of the pitch support 11. The rotation of the pitch support 11 drives the rotation of the LED screen 22, thus smoothly completing the pitch angle adjustment of the device. Finally, the ideal effect of quickly and efficiently adjusting the left and right pitch angle of the support is achieved.
