Abstract
A non-pull cord operated Venetian blind includes a blind embodiment having left/right retaining cords led through both lateral sides thereof and fixed to a windowsill at the bottom ends thereof, and a pair of clamps securely sealed at both ends of a lower beam to clamp tight the retaining cords thereby. The clamp is made up of a movable plate and a fixed plate with a spring element attached there-between. A serrated retaining section and a serrated fixing section are disposed at the corresponding inner side of the movable plate and the fixed plate thereof respectively, tightly engaged via the spring element for holding the left/right retaining cords therein in clamping location, and a step-wise coupling section is disposed at the outer side of the fixed plate thereon to securely fix the clamps thereof onto both ends of the lower beam thereby. Thus, the clamps are pushed to the compress spring elements adapted therein and detach the retaining cords there-from so that the blind embodiment is easily adjusted up or down along the retaining cords thereof into a proper position before the pressing force is removed to clamp tight the retaining cords via the clamps and precisely relocate the blind embodiment at the proper position, providing a non-pull cord Venetian blind to effectively protect the safety of children in the household. Besides, a pair of clamping devices with push rods can also be adapted to both ends of the lower beam with the same effect thereof.
