Abstract

The invention provides a pencil sleeve. The pencil sleeve comprises a pencil sleeve left portion and a pencil sleeve right portion, wherein the pencil sleeve left portion and the pencil sleeve right portion are respectively a tubular body with the two ends respectively provided with a cavity, the left end port of the pencil sleeve right portion is slightly smaller than the right end port of the pencil sleeve left portion, the cavity of the left end port of the pencil sleeve left portion is shaped like a circular truncated cone with a large outside and a small inside, and the cavity of the right end port of the pencil sleeve right portion is shaped like a hexagon with a large outside and a small inside. Compared with the prior art, the pencil sleeve is characterized in that the pencil sleeve left portion and the pencil sleeve right portion are combined, an eraser can be stored and protected, the portion wrapping the tip of a pencil has two shapes and can protect pencils of different shapes, the pencil sleeve can be inserted into the other end of the pencil to prolong the pencil when the pencil is shortened, and therefore resources are saved.

Description

A kind of pencil cap

Technical field

The present invention relates to a kind of pen cap, particularly a kind of pencil cap.

Background technology

Current pencil is all to cut to open to use shape, after cutting, is placed in writing case or pen bag, and be easy to make dirty writing case or pen bag, and fall on the ground or stab to what also frangibility, add exposed pen core outside and be also easy to hurt people.Another one problem is, current pencil otherwise be not just with rubber need to separately be joined rubber in the time of use, otherwise be exactly at a rubber of a fixed installation, but this class rubber is property for once, after being finished, cannot install again, and the impact use function of also easily making dirty that is exposed.

Summary of the invention

Goal of the invention: goal of the invention of the present invention is to provide a kind of pencil cap, can also deposit rubber in protection in pen core, and shortens cannot use time and can also play the effect that extends pencil at pencil, economizes on resources.

Technical scheme: a kind of pencil cap of the present invention, comprise pen cap left part and pen cap right part, respectively there is the cylindrical body of a cavity at described pen cap left part and described pen cap right part Dou Wei two ends, and the left port of described pen cap right part is slightly less than the right output port of described pen cap left part.

In order to make the pen cap overlap tightlyer, protect better the pen core at nib place, the cavity of the left port of described pen cap left part is the truncated cone-shaped cavity that outer imperial palace is little, the cavity of the right output port of described pen cap right part is the hexagonal cavities that outer imperial palace is little.

For the void space that rubber is deposited is enough large, the cavity of the left port of the right output port of described pen cap left part and described pen cap right part is all cylindrical cavity.

Beneficial effect: compared with prior art, its distinguishing feature is by pen cap left part and pen cap right part are combined in the present invention, can deposit rubber and play the effect of protecting rubber; And there are two kinds of shapes at the position of entangling pencil point, can protect difform pencil, and play in the pencil other end that can also be inserted in pencil cannot use time that shortens the effect that extends pencil, economize on resources.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiments of the invention;

Fig. 2 means the cross sectional representation of two ports of pen cap left part in Fig. 1;

Fig. 3 means the cross sectional representation of two ports of pen cap right part in Fig. 1;

Fig. 4 means pen cap left part and pen cap right part combination schematic diagram in Fig. 1.

The specific embodiment

Fig. 1 has provided embodiments of the invention structural representation.As shown in Figure 1, a kind of pencil cap of the present invention, comprises pen cap left part 1 and pen cap right part 2, and respectively there is the cylindrical body of a cavity at pen cap left part 1 and pen cap right part 2 Dou Wei two ends, and the left port 21 of pen cap right part 2 is slightly less than the right output port 12 of pen cap left part 1.

During use, the right output port 12 that the left port of pen cap right part 2 21 is inserted pen cap left parts 1 forms an integral body, and rubber can leave in the large cavity that two cavitys of left port 21 and right output port 12 form, and can be protected and can also change at any time.The left port 11 of pen cap left part 1 and the right output port 22 of pen cap right part 2 can be inserted on nib, are used for protecting pencil-lead, simultaneously in the pencil other end that can also be inserted into pencil cannot use time that shortens, play the effect that extends pencil, economize on resources.

The cavity of the left port 11 of pen cap left part 1 is the truncated cone-shaped cavity that outer imperial palace is little; the cavity of the right output port 22 of pen cap right part 2 is the hexagonal cavities that outer imperial palace is little, can be applicable to difform pencil, and the outer little design of imperial palace of cavity; make the pen cap overlap tightlyer, protect better the pen core at nib place.

The cavity of the right output port 12 of pen cap left part 1 and the left port 21 of pen cap right part 2 is all cylindrical cavity, and the space that rubber is deposited is enough large.

Claims
