[0016] A worm wheel 12 located at the front side of the base 5 is coaxially fixed to the first rotating shaft 8 . A second rotating shaft 13 is rotatably connected to the base 5 . A worm 14 meshing with the worm wheel 12 is coaxially fixed to the second rotating shaft 13 .

[0017] In order to protect the first monitor 2 and the second monitor 3, a triangular shield 15 is fixed to the upper end of the guide rail 4, and grid shields 16 are fixed on the left and right sides of the shield 15. The lower end of the grid shield 16 is fixedly connected to the base 1, and the second rotating shaft 13 is rotatably connected to the grid shield 16 on the right side. The second rotating shaft 13 is coaxially fixed with a handle 17 located on the outside of the grid shield 16.
