Abstract

The utility model provides a pencil sharpener belongs to the cultural tool, which is composed of a casing and a cutter inside the casing. The casing is composed of a box body opened on one side and the box cover of a closed box body, and the casing is provided with a rotary shaft hole, a sliding curved hole, a guiding pencil tube and a slag hole. The both end of the rotary shaft and the both end of the cutter are respectively positioned on the bottom of the box body and inside the rotary shaft hole of the box cover. The both end of a sliding shaft are respectively positioned on the bottom of the box body and inside the sliding curved hole of the box cover, and the sliding shaft is fixed on any position of the sliding curved hole by using the screw cap on the bottom of the box body and outside the box cover to cause the pencil sharpener rolls out the pencil head with different conicity. The utility model satisfies the requests of people for multiplicity of the taper of the pencil head, and is suitable for the requests for rolling the pencil with pencil cores with different sizes.

Description

A kind of pencil-knife

Technical field

The utility model belongs to the cultural tools field, is a kind of cutter of pencil with wound specifically.

Background technology

At present, the blade of pencil-knife and the position of housing are fixed, and the angle of pencil and blade is also fixed naturally during volume, and the tapering of pencil with wound head is fixed, this incompatibility people's diversity requirement, the also volume of the pencil of an incompatibility different thicknesses pen core requirement.

Technology contents

The utility model purpose is can roll out the pencil with wound cutter of different taperings according to different thicknesses pen core and people to the requirement of pencil stub diversity for people provide a kind of.

The technical solution of the utility model is: pencil-knife is made and leads the adjustable structure of shaft of a writing brush relative position, with the pencil-knife pencil with wound time, the angle of adjustable pencil-knife and pencil obtains the pencil stub of different taperings.

Pencil-knife is made up of a housing and the cutter that is arranged in the housing.Housing is by having the open box body (1) of a side and the lid (7) of enclosed box body (1), is respectively arranged with rotational axis hole (2) and slip arcuate socket (3) in the same position of box body (1) end and lid (7); Also be provided with on the box body (1) and lead the shaft of a writing brush (11), and scum hole (12); The knife edge (5) two ends of cutter (4) have turning cylinder (9) and sliding axle (10) respectively, turning cylinder (9) two ends place the rotational axis hole (2) of box body (1) end and lid (7) respectively, sliding axle (10) two ends place the slip arcuate socket (3) of box body (1) end and lid (7) respectively, and box body (1) end and lid (7) external application nut (8) fixedly sliding axle (10) in any position of slip arcuate socket (3).

Leading the shaft of a writing brush is the device of stablizing the pencil position, the drafting board hole of leading near the shaft of a writing brush (11) the one ends box body (1) with being positioned at slip arcuate socket (3) joins, pencil can be inserted lead the shaft of a writing brush to contact, intersect or be close so lead the angle of cut point (13) of the extensions of the shaft of a writing brush (11) center pillar line and turning cylinder (9) and cutter (4) with cutter.

The utility model has the advantages that the pencil stub that can roll out different taperings, satisfy the diversity requirement of people the pencil stub tapering, and the requirement can adapt to different thicknesses pen core volume the time.
