Description

Multi-refill ballpoint pen

technical field

The utility model relates to a multi-rod pen core ball-point pen which can use ball-point pen cores of different lengths and is convenient for hand-held writing, belonging to the field of ball-point pen manufacture.

Background technique

For the existing ballpoint pens on the market, after the original refills are used up, compatible refills are often not available. Because the refills are not available, the ballpoint pens cannot be used; The situation that the penholder slides occurs, which affects the effect of writing.

Contents of the invention

Design purpose: To avoid the shortcomings in the background technology, to design a multi-core ballpoint pen that can use different lengths of pen cores and prevent the pen holder from sliding when writing.

Design scheme: In order to achieve the above purpose. 4～6 plastic rods adopt elastic rings to be wrapped on the pen core and form the multi-bar pen core round pen, which is the main technical characterictic of the utility model. The purpose of doing this is: first, by adjusting the elastic ring on the pen holder, the positions of the pen cores of different lengths in the multiple plastic rods can be adjusted and fixed by the elastic ring, so that it can achieve the purpose of normal writing; Because the rods of the multi-rod pen core ballpoint pen are rods with distinct concave and convex, when the ballpoint pen is held in hand for writing, it can effectively prevent it from rotating and sliding, so that it is convenient for writing.

Technical solution: a multi-rod refill ballpoint pen, which includes a ballpoint pen, 4 to 6 plastic rods are wrapped on the refill with elastic rings to form a multi-rod refill ball pen.

Compared with the background technology, the utility model has the following advantages: one is that pen refills of different lengths can be conveniently used; the other is that the structure design is novel, unique, simple, practical and low in manufacturing cost; raw material consumption.

Description of drawings
