[0042] When it is necessary to lower the height of the main display board 1, the second motor 29 is started, and the second motor 29 drives the second screw 28 to rotate. Since the second screw 28 is threadedly connected to the lifting column 26, the lifting column 26 moves downward along the limiting shell 27, and the lifting column 26 drives the main display board 1 to move downward, so as to facilitate writing or posting of engineering information at a high place on the main display board 1.
