Abstract
The utility model discloses a pencil sharpener with a short cutting edge. The cutting slot of a common pencil sharpener is fixed with a cutting blade by screws. The pencil sharpener with a short cutting edge is characterized in that the cutting blade is shorter than the jack of a pencil, and the side of an outer shell is provided with coating grinding aids. The cutting blade only can cut the wooden part of the pencil without cutting the pencil core, for the cutting blade is shorter than the jack of the pencil, so that the pencil core can not be broken by the cutting blade. With simple structure, the utility model efficiently solves the technological problem that pencil sharpeners often break pencil cores.
Description
The utility model relates to a kind of stationery that sharpens a pencil, and specifically relates to a kind of short sword pencil sharpener.
Pencil sharpener (claiming penknife again) is the stationery that people use always, particularly requisite schooling apparatus in students in middle and primary schools' study.Though but the employed pencil sharpener profile of people is different at present, its action principle all is the same, and pencil sharpener all is that the wooden part of pencil is cut simultaneously with lead for retractable pencil when roll cutting pencil, because blade and pencil are essentially parallel construction.Like this, lead for retractable pencil is subjected to the cutting force of a vertical direction when roll cutting pencil, and this cutting force decomposites a bending force; When the blade of pencil sharpener was very sharp, pen core still was difficult for being fractureed, but after pencil sharpener uses very short time, edges dull, when cutting pencil power strengthened, lead for retractable pencil is just very easy to be fractureed.And, because pen core and wooden part are cut simultaneously when roll cutting pencil, like this pen core tend to be pruned many, thereby shortened service life of pencil, cause waste.This be one for a long time people thirst for solving but the technical barrier that do not obtain as yet satisfactorily resolving.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple, can effectively prevent the short sword pencil sharpener that pencil-lead fractures in use.
Below in conjunction with accompanying drawing content of the present utility model is described in detail, but content of the present utility model is not limited to shown in the accompanying drawing.
Fig. 1 is the front view of short sword pencil sharpener;
Fig. 2 is the side view of pencil sharpener shown in Figure 1.
The utility model is by cutter groove (1), shell (2), and screw (3), blade (4), Pencil jack (5), coated abrasive material (6) forms. It is characterized in that at cutter groove (1) logical Cross screw (3) and be fixed with a blade (4) shorter than pencil jack (5), in shell (2) Side or the back side be provided with one deck coated abrasive material (6). The length of blade (4) can be pencil and inserts The 1/2-3/4 of hole (5) length.
Wherein the blade of the blade of the utility model pencil sharpener (4) can be straight sword or the oblique sword of arc.
The use of the utility model pencil sharpener and the use of common pencil sharpener are basic identical, pencil that at first will be to be cut inserts pencil jack (5), rotate to clockwise direction, because blade is shorter than pencil jack, therefore blade can only be rolled up the wooden part of cutting pencil, do not cut pen core and do not roll up, thus the possibility of having avoided pen core to be fractureed by blade.The pencil that volume is cut takes out from jack, according to the needs of oneself the coated abrasive material (6) of pencil-lead on the pencil sharpener shell is gone up the grinding taper again and gets final product.
Though the utility model structure is simple, is skillfully constructed, and has successfully solved the technical barrier that pencil sharpener usually fractures pencil-lead, has excellent popularization and be worth and market prospects.
Embodiment
On the cutter groove (1) of common pencil sharpener, be provided with a short angle of throat sheet (4), wherein the length of blade (4) have only pencil jack (5) 2/3rds, be provided with coated abrasive material (6) at the right flank of pencil sharpener shell (2).
