Abstract
A curtain drawstring structure may include an upper beam, a fixed unit, and a movable unit. The upper beam has a rail groove for a string hole, and a projecting rail is protrudingly disposed at a lower portion of the inner wall of each rail groove, and an evading space is used to separate the two projecting rails. Through the size difference of guiding wheels and steering wheels and the engagement of pressing rods and stepped slots of the fixed unit and movable unit, a retractable cord can be fully separated to avoid entanglement. The retractable cord can be simply wrapped on the guiding wheels and steering wheels to complete the installation process.
