ABSTRACT:
A window blind is constructed to include a headrail, a blind body suspended below the headrail, a linking mechanism mounted inside the headrail and having a power input device fastened pivotally with the headrail and an actuator rotatable with the power input device and connectable to the blind body, and a driving control mechanism. The driving control mechanism includes a suspension rod suspended from the headrail and a controller detachably coupled to the suspension rod for enabling the suspension rod to be driven by the controller to rotate the power input device and to further drive the actuator to move the blind body, causing the blind body to change the window shading status.
