A movable groove matching the slider 350 is opened in the rotating plate 310, and the slider 350 is slidably connected to the movable groove. The bidirectional threaded screw 330 is connected to the fixed seat 320 through a bearing. The clamping surfaces of the two groups of movable splints 360 are fixedly installed with rubber pads 370. A sliding groove 380 is opened at the bottom end of the front side of the rotating plate 310, and an L-shaped support block 390 is slidably connected in the sliding groove 380.

[0028] First, manually slide the interval between the two groups of L-shaped support blocks 390 according to the size of the LCD device. After adjustment, the staff will place the LCD device on the L-shaped support block 390, and then rotate the turntable 340 to drive the bidirectional threaded screw 330 to rotate, so that the two groups of sliders 350 move relative to each other within the limitation of the movable groove, and drive the two groups of movable clamping plates 360 to move relative to each other until the two sides of the LCD device are clamped and fixed. By setting the rubber pad 370, the movable clamping plate 360 ​​is prevented from squeezing the LCD device to deform it.

Then, according to actual needs, the height of the LCD device can be adjusted by starting the electric push rod 210, and the first motor 250 is started. The output end of the first motor 250 drives the worm 260 to rotate, thereby driving the worm gear 240 meshing therewith to rotate, driving the rotating shaft and the flip bracket 230 to rotate, so that the LCD device can be flipped 180 degrees in the vertical direction. It can also be driven by the second motor 280 to adjust the LCD device in the horizontal direction. The adjustment is very convenient and efficient.

[0033] When in use, first manually slide the interval between the two groups of L-shaped support blocks 390 according to the size of the liquid crystal display device. After adjustment, the staff will place the liquid crystal display device on the L-shaped support block 390, and then rotate the turntable 340 to drive the bidirectional threaded screw 330 to rotate, so that the two groups of sliders 350 move relative to each other under the limitation of the movable groove, and drive the two groups of movable clamping plates 360 to move relative to each other until the two sides of the liquid crystal display device are clamped and fixed. By setting the clamping assembly 300, liquid crystal display devices of different sizes can be fixed, which improves the practicality of the device, and then it can be used according to actual needs. The height of the liquid crystal display device can be adjusted by starting the electric push rod 210, and the first motor 250 is started.
