CN201192950Y - Telescopic pen cover - Google Patents

Abstract

The utility model relates to a pencil pouch, in particular to a telescopic pencil pouch. The pen pouch is characterized in that two to four segments of sheathes are arranged in the pen pouch; each segment of the sheath has different diameter from others; and an edge folding from outside to inside is formed on the top end of each segment of the sheath for achieving sheath-connection between the segments of the sheath. When using a shorter pencil, the pencil can be sheathed in the pouch. When the pencil is short, the pencil in the pouch can be drawn from the pouch for further use until the pencil is used up, thereby improving the utilization efficiency of the pencil, reducing wood consumption, protecting the environment and saving energy. The pencil pouch has the advantages of simple structure and low cost, and can be easily popularized and applied in schools.

Description

The scalable pen cap

Technical field

The utility model relates to a kind of pen cap, relates in particular to a kind of scalable pen cap.

Background technology

The pupil advocates with the pencil that can cut in school and uses, and generally can not adopt propelling pencil, and the existing pen cap is shorter, sharpens a pencil with after short, and finger is pinched incessantly pencil, generally causes waste with regard to abandoning.

Summary of the invention

Have defective for overcoming prior art, the utility model provides a kind of length that had both increased the pen cap, saves the scalable pen cap of the timber use of pencil again.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of scalable pen cap comprises the pen cap, is characterized in, the more piece sleeve pipe is set in the pen cap, diameter difference between described every joint sleeve pipe, and every joint cannula tip is provided with the ecto-entad flanging, is used for socket mutually between every joint sleeve pipe.

Sleeve pipe is 2 to 4 joints.

The beneficial effects of the utility model: when pencil uses more in short-term, can put the pen cap, pull out on the pen cap sleeve pipe and continue again to use with having lacked and can having adopted when putting pen cap pencil, until pencil being used up, both increased the pencil service efficiency, the timber of having saved pencil again uses, environmental protection and energy saving, the utility model is simple in structure, and cost is low, is easy to school and applies.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1: a kind of scalable pen cap, comprise the pen cap 2, be characterized in, more piece sleeve pipe 1 is set in the pen cap, diameter difference between described every joint sleeve pipe, every joint cannula tip is provided with the ecto-entad flanging, is used for socket mutually between every joint sleeve pipe.Sleeve pipe is 2 to 4 joints.When pencil uses more in short-term, can put the pen cap, pull out with having lacked and can having adopted that sleeve pipe continues use again on the pen cap when putting pen cap pencil, until pencil being used up.

Claims (2)

1. a scalable pen cap comprises the pen cap (2), it is characterized in that, more piece sleeve pipe (1) is set in the pen cap, diameter difference between described every joint sleeve pipe, and every joint cannula tip is provided with the ecto-entad flanging, is used for socket mutually between every joint sleeve pipe.

2. the scalable pen cap according to claim 1 is characterized in that, described sleeve pipe is 2 to 4 joints.
