Abstract
An adjustment device for a drawstring of a curtain with a curtain body includes a base fixed to a bottom end of the curtain body and defining a shaft hole, a reel received and rotatably mounted in the shaft hole of the base, and a locking assembly for limiting an axial displacement of the reel. A sidewall bounding the shaft hole of the base defines a through slot. The base forms a number of first positioning portions distributed in a circle about a central axis of the shaft hole. An end of the drawstring passes through the through slot of the sidewall bounding the shaft hole and is wound on the reel. The reel forms a number of second positioning portions cooperating with the first positioning portions to prevent the reel from rotating.
