Abstract
An electric pencil sharpener includes a frame, a first motor, a first transmission mechanism driven by the first motor, and a continuing feeding mechanism. The feeding mechanism includes a roller, a feeding wheel rotatably mounted to the frame and driven by the first transmission mechanism, and a driving assembly. An end of the driving assembly is driven by the first transmission mechanism, and the other end of the driving assembly is connected to the roller. The roller defines a groove in a bottom thereof, for pencils falling through. The feeding wheel defines a plurality of receiving slots each for receiving a pencil. The roller is driven by the driving assembly to swing, when the groove of the roller aligns with one of the receiving slots of the roller. Thus, a pencil falls into the receiving slot.
