Abstract

The utility model relates to a telescopic pen which comprises a connecting part, adopts a telescopic rod-shaped structure formed by rolling a strip sheet, and has a first end and a second end, wherein the first end is connected with an inner pen case, and the second end is connected with an outer pen case; the inner pen case is provided with a containing space which can contain a refill and is connected with the second end of the connecting piece; the inner pen case can be contained in the containing space of the outer pen case, can partially or completely extend out of the containing space of the outer pen case, and can realize axial rotation with a relative position of the outside space in the containing space of the outer pen case. The telescopic pen has the following advantages: a user can adjust the length of the connecting part in a manner of applying force to the inner pen case and the outer pen case, and the telescopic pen can be used for adjusting the whole length of the a writing tool to be fit with the fingers and the holding length of the user, thus achieving the optimal using effect.

Description

Scalable pen

Technical field

The utility model relates to a kind of scalable pen.

Background technology

The shortcoming of existing pen mainly is to be unfavorable for carrying and using.Main cause is: the entire length of writing implement can't flexibly be adjusted along with user individual's requirement.For instance, when writing implement integral body is oversize, be unfavorable for that the darker user of pocket is carried on it in pocket,, then increased the user's of finger length use difficulty again when too little as if what writing device was designed.

Summary of the invention

The utility model provides a kind of and has been convenient for carrying, can carry out the pen of telescopic adjustment; Solve existing pen and can not carry out the problem that length is regulated, the technical scheme of taking is: a kind of scalable pen, a connection piece; Adopt rectangular lamellar body to be rolled into telescopic rod-like structure; Have first end and second end, pen container in its first end connects, second end connects outer pen container; Interior pen container, have can ccontaining pen core accommodation space, and be connected in second end of connector; Should in pen container be can be contained in the accommodation space of this outer pen container, and can partly or entirely protrude out outside the accommodation space of this outer pen container of place, and be somebody's turn to do interior pen container can be outside this accommodation space of pen container and the relative position of space outerpace carry out axial rotation.

The advantage of the utility model is: the user can be by the mode of the application of force and interior pen container and outer pen container; The length of adjustment connector; Be used for regulating the entire length of writing implement, meet user's finger and the length that grips, reach best result of use.

Description of drawings

Fig. 1 is the sketch map of the concrete structure of the utility model.

The specific embodiment

Below, in order fully to understand the structure of the utility model,, the utility model is done further detailed description in conjunction with Figure of description.

A kind of scalable pen comprises a connection piece 4, adopts rectangular lamellar body to be rolled into telescopic rod-like structure, has first end 3 and second end 9; Interior pen container 5, have can ccontaining pen core accommodation space, and be connected in second end 9 of connector, pen container 5, the second ends 9 connected outer pen container 2 in its first end 3 connected; Should in pen container 2 be can be contained in the accommodation space of this outer pen container, and can partly or entirely protrude out outside the accommodation space of this outer pen container of place, and be somebody's turn to do interior pen container 5 can be outside this accommodation space of pen container and the relative position of space outerpace carry out axial rotation.

Interior pen container 5 is the telescopic units 6 that possess in order to force in pen core, and in addition nib 8 is contained in the accommodation space 7 of pen container in this, and can be part or all of stretch out in accommodation space 7.And should nib can carry out axial rotation between relative position with respect to the accommodation space of interior pen container and space outerpace.Specifically, telescopic unit 6 is a knob, and the user can further rotate telescopic unit 6, make nib stretch out or the indentation accommodation space in.

The end of outer pen container has opens the end cap 1 that unloads, if connector is rolled up too loose or tension because external force applies words improperly, can carry out manual adjustments through dismantling end cap 1.

Claims (3)

1. a scalable pen is characterized in that: comprise a connection piece, adopt rectangular lamellar body to be rolled into telescopic rod-like structure, have first end and second end, pen container in its first end connects, the outer pen container of second end connection; Interior pen container, have can ccontaining pen core accommodation space, and be connected in second end of connector; Should in pen container be can be contained in the accommodation space of this outer pen container, and can partly or entirely protrude out outside the accommodation space of this outer pen container of place, and be somebody's turn to do interior pen container can be outside this accommodation space of pen container and the relative position of space outerpace carry out axial rotation.

2. scalable pen according to claim 1, it is characterized in that: interior pen container is to possess in order to force in the telescopic unit of pen core, and this telescopic unit is a knob.

3. scalable pen according to claim 1, it is characterized in that: the end of outer pen container has opens the end cap that unloads.
