Abstract
The invention discloses a crank handle type pencil sharpener which comprises a front cover (1), a rear shell (2), a plane cutter core (3) and a pencil holding sleeve (4). The front cover of the crank handle type pencil sharpener is provided with a cutter core support, a push rod hole and a clamping opening. The rear shell is provided with a rotary handle, a push core hole, a chip containing bin and a guide rib. The plane cutter core is composed of a cutter core base, a conical guide hole, a broken core push rod and a plane cutter blade. The pencil holding sleeve is provided with a sleeve flange and a clamping hook. The front cover is connected to the left face of the rear shell in a buckled manner. The chip containing bin is defined by the front cover and an inner cavity of the rear shell. The cutter core support is located at the upper portion inside the chip containing bin. The plane cutter core is fixed to the interior of the cutter core support through the pencil holding sleeve. In application, one end of a pencil is plugged into the conical guide hole along a cavity of the pencil holding sleeve, and a user holds the rotary handle with one hand to rotate around the pencil so as to sharpen the pencil. By means of the crank structure composed of the pencil holding sleeve, the front cover, the rear shell and the rotary handle, through the technical scheme that rotating planing force is weakened by lengthening a power arm, the user can conveniently rotate the pencil sharpener easily with little effort, and cost is reduced.
