Abstract

The utility model provides a cutter for cutting color pencils, the cutter consists of a cutter carrier with a conical pipeline, and a cutting blade. One end of the cutter carrier is provided with an inlet opening for round color pencils, the blade and a pencil shaving outlet opening are arranged above the cutter carrier, a pencil lead outlet opening is arranged at the other end of the cutter carrier, the blade for cutting the wood part has a linear structure, the blade for cutting the color pencil lead is bent along the central position of the pencil lead towards the pencil lead outlet end and the central line bevel surface, the pencil lead blade bent in the way can increase the cutting edge length, reduce the resistance encountered when cutting the color part, and thus reduce the breaking off probability of the pencil lead.

Description

The crayon sharpener

Technical field

The utility model relates to a kind of cutter, especially cuts the cutter of colored pencil.

Background technology

The general hand cutting tool that adopts when cutting colored pencil at present, cutting is inconvenient like this; Also have and adopt pencil sharpener to cut, but because the edge of a knife of pencil sharpener is shorter, resistance is big, causes fractureing of crayon core easily.

Summary of the invention

Task of the present utility model provides a kind ofly can cut colored pencil and the cutter of the pen core that do not fracture.

For achieving the above object, the scheme of the utility model employing is:

A kind of cutter that cuts colored pencil, by forming by the knife rest and the cutting tip of cone-shaped pipe, knife rest one end has circular crayon inlet port, there are blade and pen bits outlet in the knife rest top, the knife rest other end has the pen core outlet, the blade that it is characterized in that cutting wooden part is a linear structure, and the blade that cuts colored pen core is to the pen core port of export and the bending of center line inclined-plane along the pen core center.

Wan Qu pen core blade can increase knife edge length like this, and the resistance that runs into when reducing to cut colour just can reduce the pen core probability that fractures.

Description of drawings

Fig. 1 is the import side cross-sectional view, and Fig. 2 is the outlet side cross-sectional view.

Wherein: 1. penknife knife rest; 2. crayon inlet port; 3. pen is considered outlet to be worth doing; 4. cut wooden blade; 5. pen core blade; 6. pen core outlet.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further: in knife rest (1), crayon enters from crayon inlet port (2), in rotation process, wooden shell cut wooden blade (4) cutting, wood chip is discharged from outlet (3), pen core is stripped from out gradually, pen core continues to advance to pen core outlet (6), cut by the pen core blade (5) on inclined-plane, like this because pen core blade (5) chamfer distance is long, relatively mild, the pen core of fragility is had only smaller cutting dynamics, just ensured also that pen core is unlikely to fracture.

In addition, can make the angles of cutting wooden blade and pen core blade maintenance 100～135 degree.

In the practical application, fracture probability than reducing more than 70% originally.

Claims (1)

1. crayon sharpener, by forming by the knife rest and the cutting tip of cone-shaped pipe, knife rest one end has circular crayon inlet port, there are blade and pen bits outlet in the knife rest top, the knife rest other end has the pen core outlet, the blade that it is characterized in that cutting wooden part is a linear structure, and the blade that cuts colored pen core is to the pen core port of export and the bending of center line inclined-plane along the pen core center.
