Ladder drum for venetian blind
A ladder drum is mounted in a head rail of a Venetian blind for securing a ladder cord thereto, and includes a drum body installed on a tilt bar of the blind. An upper portion of the drum body is formed into an open-topped recess, which has two sidewalls interconnected by an end wall. A holder set is provided in the recess, such that a clearance is existed between the holder set and each of the sidewalls and a limiting space between the holder set and the end wall for receiving a securing element therein. The securing element is a rectangular frame has a rear end turnably received in the limiting space and a front end releasably engaged with a front side of the holder set to thereby firmly press two free ends of the ladder cord in the drum body against the two sidewalls of the recess.
