Abstract: The present invention provides an electric pencil sharpener, and pertains to the field of mechanical technology. It resolves the issue that existing electric pencil sharpeners are unable to be switched off automatically when emptying the shavings debris. The present electric pencil sharpener comprises a housing, and a power receptacle is fixed to the housing. The electric pencil sharpener also comprises a base. The housing is placed on the base, while a power connector is fixed to the base. The power connector is electrically connected to the power receptacle, and a locating structure is arranged between the housing and the base to circumferentially secure the housing and the base. It has the advantages that the power is cut off automatically while the normal service performance is ensured.
