Abstract

The utility model relates to a single-hole double-blade pencil sharpener, which comprises a frame, a conical pencil sharpening hole capable of accommodating one head of a pencil is formed on the frame, and the pencil sharpening hole is provided with a blade respectively along two opposite conical buses. The blades can be fixed on the frame through screws. When the pencil is rotated, the pencil body is sharpened by the two blades simultaneously so as to improve the sharpening efficiency by one time, so for the single-hole double-blade pencil sharpener, the pencil only needs to be rotated by half of the number of turns of the pencil for the conventional pencil sharpener to achieve similar sharpening effect, and the efficiency is improved.

Description

A kind of single hole double blade pencil sharpener

Technical field

The utility model relates to the pencil sharpener that a kind of roll cutting pencil is used, and especially is oppositely arranged two blades in the hole relevant for a kind of cutting at a volume, improves the pencil sharpener of roll cutting pencil efficient with this.

Background technology

Pencil sharpener is a kind of common stationery, and it generally all has a hole for the pencil insertion, and it is conical that the hole is, and the side in the hole is fixed with the blade that a cutting pencil is used.During use pencil is inserted and rotated a few, just the insertion end volume of pencil can be whittled into conical for use.But this pencil sharpener has individual shortcoming, and promptly to cut efficient lower for volume.Therefore imagination like this is arranged, the volume that promptly wants to reach identical is cut effect, if half that pencil only can be rotated that this conventional roll graver rotates the number of turns will be very good.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of pencil sharpener, and this kind pencil sharpener rotation pencil in the process of roll cutting pencil just can reach similar volume to half of the conventional roll graver number of turns and cut effect.In order to solve the problems of the technologies described above, the utility model provides a kind of single hole double blade pencil sharpener, and this pencil sharpener comprises a framework, is formed with a conical pen-rolling hole on the framework, and two relative element of cones of pen-rolling hole upper edge respectively are equiped with a blade.

The beneficial effect that the utility model brought is in rotation pencil, article two, blade cuts the body of pencil simultaneously, therefore only need to rotate the conventional roll graver and need rotate about half of the number of turns, can reach similar cutting effect, efficient is improved.

The specific embodiment

Referring to figs. 1 to 7, the utility model is a kind of single hole double blade pencil sharpener 1.This pencil sharpener 1 includes a framework 10, is formed with a conical pen-rolling hole 20 that can hold one of pencil on the framework 10, and two relative element of cones of pen-rolling hole 20 upper edges respectively are equiped with a blade 31 and 32.

Blade

31,32 can be fixed on the framework 10 by screw 33.

In use, the user can need roll up the pencil (not shown) end cut and inserts pen-rolling hole 20 and begin rotation pencil then.Different with traditional single blade pencil sharpener is, in the utility model, the body of pencil contacts with two

blades

31 and 32 simultaneously, and in rotation pencil, two

blades

31 and 32 cut the body of pencil simultaneously, and stock-removing efficiency is doubled.Therefore for single hole double blade pencil sharpener 1 of the present utility model, only need to rotate the conventional roll graver and need rotate about half of the number of turns, can reach similar cutting effect, efficient is improved.

Known to those skilled in the art, drawings and Examples of the present utility model are only for illustrating that function of the present utility model, structure and principle should not become the restriction in the utility model understanding; Simultaneously, the purpose of this utility model all realizes.The foregoing description may be had some change under the situation that does not break away from the utility model principle, so protection of the present utility model should be as the criterion with the scope described in claims.

Claims

1. a single hole double blade pencil sharpener (1) is characterized in that comprising a framework (10), is formed with a conical pen-rolling hole (20) on the framework (10), and two relative element of cones of pen-rolling hole (20) upper edge respectively are equiped with a blade (31,32).

2. single hole double blade pencil sharpener as claimed in claim 1 (1) is characterized in that described blade (31,32) is to be fixed on the framework (10) by screw (33).
