Abstract
The invention provides a duplex pencil sharpener which comprises a rotating cutting tube, a cutting opening and blades. The rotating cutting tube comprises a pencil holder cone tube and a pencil lead cone tube which is arranged at the end of the pen holder cone tube. The taper of the pencil holder cone tube is larger than the taper of the pencil lead cone tube, the cutting opening is longitudinally arranged in the rotating cutting tube, and the blades are fixed on the cutting opening. The blades comprise a pencil lead blade arranged on the pencil lead cone tube and a pen holder blade arranged on the pen holder cone tube. According to the duplex pencil sharpener, the pencil holder blade and the pencil lead blade are mounted on the pencil holder cone tube and the pencil lead cone tube which have different tapers, thus the pencil holder blade and the pencil lead blade have different tapers, and cutting of different tapers can be conducted on a pencil lead and a pen holder.
Description
Technical field
The present invention relates to the office appliance field, relate in particular to a kind of compound pencil sharpener.
Background technology
Existing pencil sharpener includes only a blade, thereby has only a tapering with the pencil that it cuts out, has caused the inconvenience of using.Application number a kind of pencil sharpener that has been 201020125125.4 disclosure of the Invention, its penholder blade has different gradients with the pen core blade, thereby can carry out the cutting of different taperings with penholder at pen core.But its tool rest partly has only a tapering, causes in the actual cut, and pencil-lead can be subjected to overstocking of tool rest and rupture, and the actual not work of pen core blade.That is, because the unreasonable cause of shape of above-mentioned novel tool rest causes actual can't work.
Summary of the invention
Purpose of the present invention provides a kind of compound pencil sharpener, solves in the above-mentioned prior art problem one or more.
