[0018] 1. This utility model, by setting an adjustment mechanism, can adjust the display screen when its height is not suitable for the viewer's height. By starting the motor, the motor will drive the first bevel gear to rotate, which in turn drives the second bevel gear to rotate around the bearing seat. The lead screw will rotate synchronously with the second bevel gear. When the lead screw rotates, it will drive the transmission frame, causing the transmission frame and the display screen to move up and down under the constraint of the sleeve and support rod. When the appropriate position is reached, the motor can be turned off, thus achieving the function of adjusting the display screen. At the same time, the lead screw transmission method is more stable.

[0019] 2. This utility model, by setting up an unfolding mechanism, allows the connecting block to move away from the support block by activating an electric push rod after the display screen height is adjusted. Under the constraint of the telescopic block and telescopic groove, the connecting block will drive the counterweight block to move away from the base. The two counterweight blocks, as... Figure 4 As shown, the display is in an unfolded state, which distributes the center of gravity of the display device to both sides, thereby improving the overall stability of the display device.

[0020] 3. By setting up a support mechanism, this utility model can improve the overall stability of the display device when the terrain at the entrance is uneven. This is achieved by holding the screw block and rotating it. The screw rod rotates in the threaded hole and moves downward, pushing the support block downward so that it contacts the ground. By repeating the above steps, the support blocks of the four support mechanisms are brought into contact with the ground in turn. Attached Figure Description
