Abstract

The utility model relates to a pen with a sable sleeve, which is suitable for students or relative technical staffs, via which users can only take one tool to realize the functions of a pen and a graduated scale, having simple use. The utility model fits and sheaths a sleeve on the outer layer of a common pen and provides scales on the sleeve, therefore, when in use, the sleeve can be removed easily and the utility model can be used as a graduated scale. Compared with the prior pens, the production cost is not increased mush, and the utility model has simple use and wide application.

Description

The pen of band dial sleeve

Affiliated technical field

The utility model relates to a kind of writing with the combination of pen with rule, is applicable to the use of student or person skilled.

Background technology

Many people often run into need be simultaneously with pen and rule, for example student examination or technical staff's measurement data the time, often leave behind but that certain is the same, seem very inconvenient.Now some producer notices this situation, designed a kind of with scale directly be engraved on the pen cap with pen, solved this problem to a certain extent.But, the pen cap to be taken in the time of use, can only map with pen core, perhaps to have two pens simultaneously and just can implement operation, also convenient inadequately.

Summary of the invention

Just can have pen and the rule of writing in order to reach with article, and purpose easy to use, the utility model adopts this scheme of sleeve that puts a band rule at the skin of general pen universal, well reaches above-mentioned requirement.

The concrete technical scheme of the utility model is: design the pen (water-color paintbrush or ball pen) of a band dial sleeve, its pen cap divides inside and outside two-layer, and internal layer is transparent, is holding under the comfortable prerequisite of pen, and the internal layer pen cap is tiny as far as possible; Outer pen cap internal diameter is the external diameter of the identical internal layer pen cap just, and length slightly is longer than the internal layer pen cap, and engraves scale on the sidewall of the outer pen cap.When not needing rule, in the inside and outside two-layer pen cap is held in the hand together, as using a common pen; When needing rule, just the outer pen cap can be taken off, use, not influence comfortableness simultaneously with pen as rule.

It is inside and outside two-layer that great advantage of the present utility model is exactly that the pen cap with general pen universal is divided into, and at outer calibrate, thereby can easily the one-pen that carries with sound be divided into two.This pen after improving does not more increase too many production cost with existing pen, and easy to use, is bound to be subjected to user's favor.

The specific embodiment

Design the pen (water-color paintbrush or ball pen) of a band dial sleeve, its pen cap divides inside and outside two-layer, and the internal layer pen cap (3) is transparent, is holding under the comfortable prerequisite of pen, and the internal layer pen cap (3) is tiny as far as possible; The outer pen cap (1) internal diameter is the external diameter of the identical internal layer pen cap (3) just, and length slightly is longer than the internal layer pen cap (3), and engraves scale (2) on the sidewall of the outer pen cap (1).

When not needing rule, in the inside and outside two-layer pen cap is held in the hand together, as using a common pen; When needing rule, just the outer pen cap (1) can be taken off, use as rule, what hold in the hand is the internal layer pen cap (3) protection pen core (4) down, like this, just can not feel that in use picture directly takes one-pen core (4) inconvenience so.

Claims (1)

1, a kind of pen with dial sleeve, it is characterized in that: the pen cap divides the internal layer pen cap and sleeve two-layer, and sleeve diameter is the external diameter of the identical internal layer pen cap just, is carved with scale on the sidewall of sleeve.
