[0038] The first screen is connected through the first supporting structure 4, and the first supporting structure 4 can be rotated around the supporting column 2 through the first supporting sleeve 3 to achieve the adjustment of the lateral angle. Similarly, the second screen is connected through the second supporting structure 40, and the second supporting structure 40 can be rotated around the supporting column 2 through the second supporting sleeve 30 to achieve the adjustment of the lateral angle. When the height of the second screen needs to be adjusted, the top sleeve 31 can be rotated, and the top sleeve 31 can be threadedly matched with the external thread structure 35 of the supporting column 2 through the internal thread structure 34 to achieve the lifting movement, thereby adjusting the height of the screen; after adjustment, there is no need to use an additional supporting structure to stop the second supporting sleeve 30, thereby achieving the effect of quick adjustment.

[0039] Specifically, since the top sleeve 31 and the bottom sleeve 32 of the second support sleeve 30 are connected by a plane bearing 33, that is, when the top sleeve 31 is rotated to adjust the height, the bottom sleeve 32 will not rotate, and when the height of the top sleeve 31 changes, the bottom sleeve 32 also changes with the height of the top sleeve 31, and will not affect the angle of the second support structure 40 installed on the bottom sleeve 32.

[0040] The bottom seat 21 is provided with a fixed structure 1, which includes a top plate 11 installed on the bottom seat 21 and a bottom plate 12 installed parallel and spaced below the top plate 11, and the bottom plate 12 is installed with a clamping plate 13 that can be close to or away from the top plate 11; when the driving bracket needs to be installed, the top plate 11 and the bottom plate 12 can be inserted into the table top, and then the clamping plate 13 is driven to move close to the top plate 11, and the bottom seat 21 is fixedly installed on the table top and other areas through the clamping plate 13 and the top plate 11.

[0041] A top limiting ring 25 is installed on the top of the support column 2 , and the top limiting ring 25 can prevent the first support sleeve 3 from detaching from the support column 2 .
