ABSTRACT:
An adjustable structure of a curtain for adjusting the angle of curtain blades includes a winding tube disposed in an upper rail. A pulling string is wound around the winding tube for controlling the rise and fall of the curtain and then passes through the curtain blades. One end of the winding tube is disposed with a rubbing wheel for hanging the top end of a suspending string provided for insertion of the curtain blades. Thereby, during the rise and fall of the curtain blades, the suspending string is pulled towards the rotating direction of the winding tube, so that the angle of the curtain blades is adjusted.
