CN2074715U - Two awl pencil sharpener - Google Patents

Abstract

The utility model relates to a two-awl pencil sharpener, which is composed of a body, a lead cutting knife, a wood pole cutting knife, screw nails, a slide plate and sand paper. Due to the adoption of the structure of double knives with different height, the sharpened pencil has a long bare lead and the lead has certain intensity; what is more important, the angle between the lead cutting knife and the wood pole cutting knife can be adjusted respectively according to the material of the pencil, thus the quality of the pencil after sharpening is enhanced; the slideway on the lower part of the two-awl pencil sharpener is provided with a slide plate, and the sharpened lead or lead with abrasion can be ground at will on the sand paper glued on the slide plate. The utility model has the advantages that the sharpened pencil has attractive appearance, long life, high holding position and few times of sharpening; the grinding of the lead is convenient; the two-awl pencil sharpener is suitable for students and drawing personnel.

Description

Two awl pencil sharpener

The utility model relates to a kind of pencil sharpener that sharpens a pencil.

No matter existing its profile of pencil sharpener how, its basic structure is that a blade is fastened on by the taper hole groove.Pencil rod and pen core profile that volume is cut out are on the conical surface of same garden.The pencil-lead that exposes is short and sharp.Make very quick-wearing of short and sharp pen core so first, so must frequently use the pencil sharpener volume to cut.Second easily make pen griping position on the low side, cover user's sight line, especially to designer's inconvenience, so they prefer to use blade to sharpen a pencil.

The purpose of this utility model provides a kind of bipyramid pencil sharpener, makes the pen core that exposes long, has certain intensity again, reduces the number of times that volume is cut, arbitrarily the reconditioning pen core.

The utility model be achieved in that the bipyramid pencil sharpener by body, cut the pen core cutter, cut rod cutter, screw, slide plate and rubber and form.With body on the angled center line in plane, make to have import post hole, rod taper hole, reservoir hole successively.Have elongated slot on the hole wall by the center, at the other rod blade, pen core blade of being equipped with successively of elongated slot.The mounting plane of pen core blade is higher than the rod blade.The angle of wedge of rod blade is less than the angle of wedge of pen core blade.Before volume was cut, pencil was inserted in import post hole earlier, and a center and center, hole are consistent.Clockwise direction is rolled up successively and is cut rod, pen core then.The rod profile that volume is cut out is a garden conical surface, and pen core is another garden conical surface, and the centre is a transition garden cylinder.This i.e. the origin of " bipyramid pencil sharpener " title.

One slide plate that can twitch is arranged in the chute of body bottom, and the slide plate gluing has the fine sand skin, the volume cut or wear and tear after pen core can on rubber, carry out reconditioning as required, blow away the pen core ash then, slide plate can push original position, has kept clean and tidy.

The utility model has certain intensity again because the double-pole structure that has adopted differing heights to install makes the pencil dew core after volume is cut long.The more important thing is and to determine the angle of wedge of blade respectively according to wood materials and pen core material, make volume cut quality and be improved.The slide plate gluing of bipyramid pencil sharpener has rubber, arbitrarily the reconditioning pen core.Pencil after the wearing and tearing needn't be rolled up at once and cut, and after the reconditioning for several times, the side needs volume again, reduces trouble, and saves time.

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the schematic perspective view of bipyramid pencil sharpener.

1, body 2, rubber 3, slide plate 4, pen core cutter

5, screw 6, screw 7, rod cutter 8, pencil

Fig. 2 is each the part position graph of a relation by the center line section, and pencil is shaped and schemes and the signal of the blade angle of wedge.

I import post hole II rod taper hole III reservoir hole

With reference to accompanying drawing, pencil 8 is inserted in the import post I of body 1, and maintenance pencil center is consistent with the center, hole.Clockwise rotate pencil then and enter rod taper hole II successively, the reservoir hole III, volume is cut out the pencil profile with bipyramid.

Extract slide plate 3 out, reconditioning pen core on rubber 2, mill is finished, and pushes back slide plate.

Through using, the bipyramid pencil sharpener is rolled up the pencil of cutting out, and good looking appearance is durable, the pen griping position height, and it is few that volume is cut number of times, and the reconditioning pen core is convenient.More suitable to the student personnel that especially chart.

Claims (2)

1, a kind of by body, cut the rod cutter, cut the bipyramid pencil sharpener that pen core cutter, screw, slide plate and rubber are formed, it is characterized in that cutting rod and cut pen core respectively by cutting the rod blade and cutting the pen core blade and finish, cutting pen core blade mounting plane is higher than and cuts the rod blade plane, the angle of wedge of cutting the rod blade is less than the angle of wedge of cutting the pen core blade, the pencil profile that volume is whittled into is respectively by rod garden awl, and transition garden post and pen core garden awl are formed.

2, bipyramid pencil sharpener according to claim 1 is characterized in that with portable plate, there is rubber the body bottom on the plate, volume cut and wear and tear after pen core can reconditioning on rubber, after the reconditioning, portable plate restores.
