[0016] In this embodiment, the servo motor 13 is first activated to drive the rotating rod 7 to rotate. The rotating rod 7 then drives the connecting cylinder 6 to rotate, which in turn drives the support plate 8 to rotate from horizontal to vertical. The screen 9 rotates synchronously with the support plate 8. After vertical deployment, the drone can take off and display content normally. During landing, the support plate 8 is rotated in the opposite direction to the horizontal position, effectively preventing the screen from hitting the ground and improving flight safety. At the same time, the screen can be rotated to a specified angle according to the performance requirements. In addition, the electric push rod 17 is activated to push the slider 15 to move. The slider 15 drives the brake pad 16 to move and clamp the limiting plate 14. The limiting plate 14 locks the rotating rod 7 to prevent it from loosening, thereby ensuring the stability of the connecting cylinder 6, the support plate 8, and the screen 9, significantly improving overall reliability. In addition, the start and stop operations of the servo motor 13 and the electric push rod 17 are realized remotely through the wireless transmission unit and the microcontroller 10, greatly improving the convenience of use.
