Abstract

The utility model discloses a pencil sleeve, which belongs to the technical field of stationery, provides a sleeve capable of connecting two pencils together, and is particularly suitable for the interconnection of shorter pencils, the structure of the sleeve is that the cross section of the hollow tube inner cavity is circular or regular hexagon, and the thickness of the hollow tube inner cavity is matched with the thickness of a pencil holder; the utility model discloses the effectual problem of having solved the student and can not cut the pencil after the pencil point runs out when learning, also can make full use of behind the end-to-end connection of shorter pencil simultaneously, not only simple structure but also practice thrift the environmental protection.

Description

Pencil sleeve

Technical field

The utility model Pencil sleeve belongs to the stationery technical field.

Background technology

The tip of a pencil of the usefulness that learns to write on the student has been lacked, and can't oneself sharpen a pencil; When pencil use shorter and can't hold when writing, just caused great waste if all throw away, also do not have a kind of simple in structure and can device is for people to use fully with pencil now.

The utility model content

The utility model overcomes the deficiencies in the prior art, and problem to be solved is: a kind of Pencil sleeve is provided, and the sleeve pipe that two pencils can be linked together is particularly useful for interconnecting than short pencil.

The technical scheme of the utility model Pencil sleeve is: the structure of Pencil sleeve is: the cross section of hollow pipe inner chamber is circle or regular hexagon, and the thickness of hollow pipe inner chamber and the thickness of pencil holder adapt.

In the inner chamber of described hollow pipe, be vertically installed with dividing plate, be provided with groove in the center of dividing plate.

On the outer wall of described hollow pipe, be vertically installed with dog screw.

The utility model has effectively solved the problem that the student can not sharpen a pencil after last class hour, tip of a pencil used up, also can connect short pencil from beginning to end the back simultaneously and fully use economical environment-protective again promptly simple in structure.

Description of drawings

Fig. 1 is the structural representation of the utility model Pencil sleeve;

Fig. 2 is the structural representation of the utility model Pencil sleeve embodiment 1.

The specific embodiment

As shown in Figure 1, the structure of Pencil sleeve is: the cross section of hollow pipe 1 inner chamber is circle or regular hexagon, and the thickness of the thickness of hollow pipe 1 inner chamber and pencil 4 penholders adapts; In the inner chamber of described hollow pipe 1, be vertically installed with dividing plate 2, be provided with groove 5 in the center of dividing plate 2; On the outer wall of described hollow pipe 1, be vertically installed with dog screw 3.

The one side of above-mentioned dividing plate 2 is for facing directly, and another side is a concave surface.

Embodiment 1, as shown in Figure 2:

When using up tip of a pencil, the student need sharpen a pencil 4 the time, the afterbody of the tip of a pencil cut inserted an end of hollow pipe 1 and withstand the one side of dividing plate 2, the head of the pencil 4 that nib is used up inserts the other end of hollow pipe 1 and withstands the another side of dividing plate 2, can continue to write.

It is very short when pencil holder is used; hand can't be held penholder and write; and when the external diameter of pencil 4 is smaller than the internal diameter of hollow pipe 1; the sleeve pipe that can use outer wall that dog screw 3 is installed connects; the afterbody of one of them pencil is inserted an end of hollow pipe 1; the head of another pencil is inserted the other end of hollow pipe 1 and the apical head of this pencil 4 stretches in the groove 5, the head of 5 pairs of pencils 4 of groove has protective effect.After tightening each dog screw 3, can use the pencil that is lengthened out to continue to write,, can re-use a plurality of Pencil sleeves and connect if when having a plurality of short pencils to connect.

Select the Pencil sleeve of corresponding hollow pipe 1 shape of cross section according to the shape of cross section of pencil 4.

Claims

1, Pencil sleeve is characterized in that: the cross section of hollow pipe (1) inner chamber is circle or regular hexagon, and the thickness of the thickness of hollow pipe (1) inner chamber and pencil (4) penholder adapts.

2, according to the described Pencil sleeve of claim 1, it is characterized in that: in the inner chamber of described hollow pipe (1), be vertically installed with dividing plate (2), be provided with groove (5) in the center of dividing plate (2).

3, according to claim 1 or 2 described Pencil sleeves, it is characterized in that: on the outer wall of described hollow pipe (1), be vertically installed with dog screw (3).
