Abstract

The utility model relates to a retractable suspension pen capable of adjusting the length of the pen holder, comprising a plurality of pen tubes and pen caps, the sizes of the pen tubes are progressively increased, one end of each pen tube is provided with a plurality of circles of enclosed convex bodies, and a plurality of layers of smaller convex bodies matching with the enclosed convex bodies are arranged inside the other end of each pen tube. The retractable suspension pen has the following advantages: first, the length of the pen can be adjusted as users' like; second, the pen has a good look; and third, the pen can be connected with key rings and the like, is easy to carry, and can be used as a suspension member.

Description

Extension type suspension member pen

Technical field

The utility model relates to a kind of extension type suspension member pen that can arbitrarily adjust penholder length, belongs to study article and makes the field.

Background technology

The penholder length of existing pen is finished promptly fixing once manufacturing, and the service time of pen is longer, is easy to generate aestheticly tired.Secondly, the hook on the general pen can only be hung in clothes or the briefcase, and can not hang on the object such as key chain, forgets easily sometimes.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design and a kind ofly can arbitrarily adjust penholder length, and can make the extension type suspension member pen that suspension member uses.

Design: in order to realize foregoing invention.1, the size of each pen container is and increases progressively trend, and an end of each pen container is provided with some circle projections and is closure designs, and other end inside is provided with the design of the smaller projection that several layers and another projection be complementary, and this is one of technical characterictic of the present utility model.The purpose of doing like this is: the one, can make socket mutually between each pen container, and length can be determined by user oneself; The 2nd, the inner projection of the projection of pen container inside and the pen container that is connected with it is complementary, when the user with the pen cap of upper end firmly on time, can shorten the length of pen, when up pulling out, the length of the pen that stretches; The 3rd, the closure designs of each pen container one end, even the pen container that is positioned at its upper end like this when being pulled up, whole pen is still a complete integral body.2, the top of each pen container is provided with the design of hook, and this is two of a technical characterictic of the present utility model.The purpose of doing like this is that pen still has hook, can be hung on other places such as key chain when the pen container that is positioned at this pen container upper end is pulled up.

Technical scheme: extension type suspension member pen, it comprises several pen containers and the cap for brush, the size of each pen container is and increases progressively trend, and an end of each pen container is provided with some circle projections and is closure designs, and other end inside is provided with the smaller projection that several layers and projection are complementary.

The utility model is compared with background technology: the one, can arbitrarily adjust the length of pen according to the hobby of individual subscriber; The 2nd, good looking appearance; The 3rd, can be hung on key chain etc. and locate, easy to carry, and can be used as suspension member and use.

Fig. 2 is the structural representation that has the extension type suspension member pen of the cap for brush.

Fig. 3 is not for the structural representation of the extension type suspension member pen of the cap for brush.

The specific embodiment

Embodiment 1: with reference to accompanying drawing 1～3.A kind of extension type suspension member pen, it comprises several pen containers 1 and the cap for brush 2, the size of each pen container 1 is and increases progressively trend, and an end of each pen container 1 is provided with some circle projections 3 and is closure designs, other end inside is provided with the smaller projection 4 that several layers and projection 3 are complementary, and the top of each pen container is provided with hook 5.

What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.

Claims
