Abstract: A cutter assembly for an electric pencil sharpener has a cutter bracket and a cutter. The cutter bracket has a pencil sharpening hole and an engaging structure. The pencil sharpening hole is defined in the cutter bracket for a pencil to be inserted into the pencil sharpening hole. The engaging structure is formed on the cutter bracket to engage a rotating frame in the electric pencil sharpener. The cutter is mounted rotatably on the cutter bracket. Accordingly, the cutter assembly is replaceable for the electric pencil sharpener when the cutter of the cutter assembly is damaged or worn.

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.

Abstract: An apparatus for sharpening a writing instrument, e.g. an electric pencil sharpener, is disclosed as including a body for receiving a pencil for sharpening, and a base, the base having a bottom surface to support the apparatus on a surface, and the body may be positioned relative to the base in a first configuration and at least a second configuration, and when the body is positioned relative to the base in the first configuration, a longitudinal axis of the body and an axis perpendicular to the bottom surface of the base subtend a first angle, and when the body is positioned relative to the base in the second configuration, these two axes subtend a second angle which differs from the first angle.
