The driving wheel 62 is engaged with the first adapter 42 and the second adapter 43 in the moving assembly 4, and the rotation of the driving wheel 62 drives the first adapter 42 and the second adapter 43 to rotate and move, thereby moving the moving assembly 4 in the guide rail 3. The push block 41 in the moving assembly 4 moves in the guide rail 3 and can push one end of the push rod 5 to move. The other end of the push rod 5 is connected to the rotating bracket 2. Since the connection point is not at the center of rotation of the rotating bracket 2, the translational movement of the push rod 5 will make the rotating bracket 2 rotate on the mounting bracket 1, thereby achieving the purpose of rotating the screen assembly 9. When the screen assembly 9 rotates to the vertical position or the horizontal position, the second limiting piece 25 contacts one of the two first limiting pieces 15, achieving the limiting of the vertical position and the horizontal position. The single-phase power supply of the brushless motor driving motor 61 can achieve the hovering of the screen assembly 9 at any position. Manual rotation: manually rotating the screen assembly 9 generates a torque between the screen assembly 9 and the rotating bracket 2, which drives one end of the push rod 5 to rotate. Correspondingly, the other end of the push rod 5 drives the push block 41 in the moving assembly 4 to move. Since the movement trajectory of the moving assembly 4 is limited in the guide rail 3, the moving assembly 4 can only translate in the guide rail 3. At the same time, the first adapter 42 and the second adapter 43 in the moving assembly 4 push the driving wheel 62 to rotate during the translation process, finally driving the speed reduction mechanism and the driving motor 61 in the driving assembly 6 to move. In the entire process, the force for manually rotating the screen assembly 9 is the mechanism resistance of the entire device.
