Abstract

The utility model discloses a multifunction pencil sharpener for sharpening a pencil, which comprises a holder, a blade and a hand rotating adjusting screw. The utility model is characterized in that the blade is adjustable, and pencil leads with different lengths and thicknesses can be sharpened by adjusting the position of the blade by unscrewing the adjusting screw. The advantages of the existing pencil sharpeners are kept, such as the use is convenient and easy; the defect of the existing pencil sharpeners, which the specification of the pencil sharpened is single, is overcome. Therefore, the utility model has the advantages of simple structure, convenient use, and pencils for many purposes satisfying.

Description

Multifunction pencil sharpener

The utility model belongs to stationery class instrument.

At present, the function singleness of old-fashioned pencil sharpener.So-called single, the pen core specification of promptly cutting out is single, can not adapt to the multiple use of pencil.Use this pencil sharpener, can make blade in the scope of elongated hole, adjust its position by degree of tightness with the whole screw of hand adjustment.Thereby cut out the thickness difference, arbitrarily the pen core of length.

The purpose of this utility model is for a kind of improved pencil sharpener is provided, and it is more than old-fashioned pencil sharpener function, can cut out the desirable pen core of many specifications, the multi-functional pencil sharpener that designs with the multiple use that adapts to pencil.

The purpose of this utility model is achieved in that it is provided with the knife rest of an end band lead for retractable pencil elongated hole, the screw that blade that an end of blade is rounded and available hand adjustment are whole.On the basis of original pencil sharpener knife rest, knife rest is extended, widens, increases, and establish a lead for retractable pencil elongated hole at the pen core external part.Blade one end of blade is an arc.Can cut out required pen core according to the position that the requirement of pen core is adjusted blade by slack adjuster during use.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the front view according to the multi-functional pencil sharpener that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises a knife rest (1), and a blade (2) is adjusted screw (3) for one.Pen core external part at knife rest (1) is provided with lead for retractable pencil elongated hole (5); Blade part one end of blade (2) is circular arc (6), and an elongated hole (4) is arranged on the blade (2); Adjust screw (3) and cooperate with the metal nuts of casting on knife rest, blade (2) is fixing, adjust screw (3) with the hand-screw pine blade (2) is moved in elongated hole (4) scope, when arrival needed the position, screwing adjustment screw (3) can fix.When blade (2) during at lead for retractable pencil external part maximum position, the lead for retractable pencil of cutting out is cone.Along with blade (2) is shifted one's position round about gradually, the lead for retractable pencil of cutting out can be from fine to coarse, but and random length, the thickest lead for retractable pencil can make its do not cut damage exhume out.So can determine the optimum position of blade (2) according to requirement to lead for retractable pencil.
