The reinforcing rod 19 can improve the structural strength of the support column 13 and prevent swaying during use.

[0038] For details, please refer to Figure 4 As shown, the support column 13 and the shaft frame 16 are slidably installed together by the telescopic rod 15, and the support column 13 and the telescopic rod 15 are fixed together by the first fixing knob 14.

[0039] As can be seen from the above, the telescopic rod 15 can slide up and down along the support column 13, which can easily adjust the height of the shaft frame 16 and adjust the height of the green screen body 2 according to the usage requirements. The first fixing knob 14 can easily fix the telescopic rod 15 to prevent it from slipping after adjustment.

[0040] For details, please refer to Figure 4 and Figure 5 As shown, a handrail 18 is fixedly installed at the rear end of the support column 13, and a handle 33 is fixedly installed at the top of the movable sleeve 32.

[0041] As can be seen from the above, the device can be easily moved by using the handrail 18, and the movable sleeve 32 can be easily slid by using the handle 33.

[0042] Example 2:

[0044] As can be seen from the above, the rotating base 31 can be rotated through the rotating shaft 38, and the second fixing knob 17 can be used to fix the adjusted rotating base 31. The rotating base 31 can be easily adjusted to a suitable angle, and the usage angle of the green screen body 2 can be adjusted.

[0045] refer to Figure 5 and Figure 6 As shown, movable slots 39 are provided at the four corners of the front end of the rotating base 31, and the movable slots 39 are hinged to the folding arm 34.

[0046] As can be seen from the above, the folding arm 34 can be flipped through the movable slot 39, so that the folding arm 34 can drive the green screen body 2 to unfold and close.

[0047] refer to Figure 5 As shown, a limiting block 37 is fixedly installed at the rear end of the folding arm 34, and the limiting block 37 corresponds to the movable sleeve 32.
