Abstract

The invention relates to an electric pencil sharpener which comprises a machine shell and a pencil sharpening mechanism arranged in the machine shell. The pencil sharpening mechanism comprises a cutter frame, a hobbing cutter, a work hole and a transmission assembly. A first transmission part in the transmission assembly can abut against one end of a push block, and the other end of the push blockabuts against a pencil point of a pencil. A second transmission part in the transmission assembly can abut against one end of a cutter shaft, and the first transmission part and the second transmission part are in linkage. During pencil sharpening, the pencil point pushes the push block, the push block pushes the first transmission part, the first transmission part drives the second transmissionpart and enables the second transmission part to push the cutter shaft, and then the cutter shaft moves in the direction away from the second transmission part; an elastic reset part is stressed tillthe cutter shaft is located on a cutter seat through a locating structure, the cutter shaft is located, the hobbing cutter is separated from the cutter shaft, and therefore effective cutter separationis achieved; and the sharpness of a pencil lead is effectively controlled, and the situation that sharpening is excessive or the sharpness is not enough is avoided.
