Abstract

An easily retractable and extendable roller blind including: a roller blind body, including a curtain fabric; a curtain fabric fixing assembly, including a deformable member connected to a bottom end of the curtain fabric, wherein when the curtain fabric is rolled up to a predetermined position, both ends of the deformable member are fixedly connected to form the closed loop structure, the closed loop structure fixing the posture of the curtain fabric. When the deformable member is rolled up to a preset position, it forms a closed-loop structure. The present invention enables manual retraction and extension without the need for a pull cord mechanism, ensuring safe operation, applicability, low manufacturing costs, and simple, quick operation.
