A two-stage actuating device for an electric apparatus includes a driver mounted to a fixing frame of the electric apparatus and provided with a retractable rod, a link rod having one end pivotally connected with the retractable rod of the driver and the other end pivotally connected with a moveable frame of the electric apparatus, and a bracket having one end mounted to the moveable frame and the other end connected with the retractable rod in such a way that the link rod is pushed by the retractable rod within a first-stage stroke of the retable rod to drive a first-stage movement of the moveable frame, and then the bracket is pushed by the retractable rod in a second-stage stroke of the retractable rod to drive a second-stage movement of the moveable frame.
