[0003] Stage curtains need to be retracted and extended during use. When retracting, a driving motor is usually used to drive the rollers to rotate, thereby achieving the effect of reeling in the connecting ropes and curtains. However, some stages require stage curtains with an arc structure, and the use of rollers cannot achieve the reeling effect. At the same time, decorations are usually added to the curtains to enhance their aesthetics. The folded structure formed during retraction will cause problems in the subsequent use of the curtains.

[0004] According to the Chinese patent publication number CN110467061B, "A stage curtain retracting and extending device", it mainly describes the retracting of the curtain by setting a simple roller structure. However, when retracting, the decorative objects on the curtain will be squeezed by the roller, resulting in an unsightly appearance during subsequent use.
