Description

A kind of pen core

Technical field

The present invention relates to a kind of pen core, belong to technical field of stationery.

Background technology

Pen core is generally inserted in shaft of a writing brush shell, with shaft of a writing brush shell with the use of.Therefore, pen core is the part of the writing implements such as various signature pen, ball pen, gel ink pen, applies in modern society widely.At present, the pen core length provided in known technology is fixing, can not be applicable to the shaft of a writing brush shell of different length, other pocket knife or other instruments is needed to block, but the too short pen core that makes usually cut because grasping bad length cannot use, and makes troubles, and cause waste to the public.

Summary of the invention

For the deficiencies in the prior art, the invention provides a pen core.

Technical program of the present invention lies in:

The invention provides a kind of pen core, comprise nib, the shaft of a writing brush, pen and ink, anti-backflow oil, the described shaft of a writing brush is cylindrical, described nib assigns in the shaft of a writing brush, described pen and ink are filled in the shaft of a writing brush, described pen and ink are separated with ambient atmosphere by described anti-backflow oil, and the described shaft of a writing brush is provided with broken line between anti-backflow oil and shaft of a writing brush end, and described broken line is the intermittent line around the shaft of a writing brush;

The advantage herein designed is: adjust the length of pen core by the very little strength broken line that fractures, be applicable to the shaft of a writing brush shell of different length.

Preferred according to the present invention, the distance on described broken line often between adjacent two line segments is not more than 1/10 of shaft of a writing brush cross circular section girth; The advantage herein designed is: just to be fractureed broken line by very little strength.

Preferred according to the present invention, the described shaft of a writing brush is provided with many broken lines between anti-backflow oil and shaft of a writing brush end; Distance in many broken lines between adjacent two broken lines is 1mm ~ 3mm.

Beneficial effect of the present invention:

1, the described shaft of a writing brush is provided with broken line between anti-backflow oil and shaft of a writing brush end, and described broken line is the intermittent line around the shaft of a writing brush, by the length of the broken line adjustment pen core that fractures, is applicable to the shaft of a writing brush shell of different length;

2, manufacture pen core method simple, cost is lower;

3, facilitate the public to use, economize on resources.

Accompanying drawing explanation

Fig. 1 is the structural representation of pen core of the present invention;

Wherein, 1, nib; 2, the shaft of a writing brush; 3, anti-backflow oil; 4, broken line; 5, pen and ink.
