The height adjusting plate is connected to the liquid crystal display screen by bolts and the angle adjuster is connected to the left side thereof. The lower side of the adjusting device is connected to the support frame, and the high-security base is inlaid at the bottom of the support frame". In the utility model, a height adjusting plate is arranged in the adjusting device, and the height of the liquid crystal display screen can be adjusted by using the staggered structure of the height adjusting plate. Then, by rotating the rotating gear on the angle adjuster, the angle of the liquid crystal display screen is adjusted and fixed on the screw hole by the fixing bolt on the fixator, so as to achieve the purpose of fixation and improve the flexibility of the device.

[0004] However, the above method still has the following defects: the height of the liquid crystal display screen can be adjusted by the staggered structure of the height adjusting plate, but the structure is complex, and the adjustment range is small due to the limitation of the length of the movable rod. The movable rod increases the distance between the display screen and the support frame, which occupies more space. The angle of the display screen can be adjusted by the adjusting device, but it is difficult to perform stepless adjustment of its angle because the fixing bolt needs to be fixed on the screw hole.
