发明名称 Electric pencil sharpener
摘要 A pencil sharpener which includes a sliding safety shield preventing operation of the sharpener with the pencil drawer removed and further preventing a pencil to be inserted into the sharpener so as to actuate the cutter assembly unless the shavings drawer is in its fully closed position. In addition a stop for a positive stop of the sharpening process is provided in transverse relation to the cutter assembly aperture so as to impinge upon the cutter assembly and stop the cutter assembly at a zero clearance position with a holder therefor, so as to prohibit the formation of a burr or other irregularity on the pencil point.
