[0003] Therefore, the patent with publication number CN213987139U discloses a photography background frame, which includes two telescopic supports, the top ends of the two telescopic supports are detachably connected with a telescopic rod, the rod body of the telescopic support is detachably connected with a horizontal rod, the end of the horizontal rod away from the telescopic support is fixedly connected with a vertical plate, the two side walls of the vertical plate are respectively fixedly connected with a clamping plate one and a clamping plate two, the clamping plate one and the clamping plate two respectively abut the front and back surfaces of the side edge of the background cloth, the clamping plate one is threadedly connected with a plurality of bolts one penetrating the clamping plate two, the device embeds the side edge of the background cloth between the clamping plate one and the clamping plate two, tightens the bolts one, the bolts one extrude the clamping plate two and are fixed with the clamping plate one, so that the clamping plate one and the clamping plate two extrude the background cloth together, and then fix the lower end of the background cloth, improve the stability of the background cloth when shooting outdoors.

[0004] Although the background frame in the above-mentioned patent can clamp the lower end of the background cloth and improve the stability of the background cloth when shooting outdoors, the applicant finds that the current background cloth has wrinkles during use, which is a common problem. In order to ensure the shooting quality, the background cloth needs to be flattened. However, the current background frame can only realize the winding of the background cloth, and is generally simple in structure and does not have the flattening function. The background cloth may be wound in a wrinkled state, resulting in obvious indentation in a compressed state for a long time. Therefore, external tools such as an iron are needed for ironing operation in the later use, which increases the use difficulty. Based on this, we propose an improved photography background frame.
