Abstract:
The present invention relates to a cordless blind structure including a blind body further comprising a batten and a shade having an end disposed at an outer edge of the batten; a first end holder movably disposed at a first end of the batten; a second end holder movably disposed at a second end of the batten; and a limiting mechanism disposed between the blind body and the second end holder, the limiting mechanism including a resilient unit and an axial unit, the resilient unit being movably disposed at the second end holder, and the axial unit being movably disposed at the second end holder, controllably coupled to the resilient unit, and coupled to the second end of the batten. The shade is lifted or lowered by exerting a force thereon in conjunction with the limiting mechanism so as to ensure ease of use and enhance user safety.
