Description

Fountain pen with automatic water supply length that can be adjusted freely

technical field

The invention relates to an improvement in stationery, in particular to an improvement in a fountain pen whose length can be adjusted freely.

Background technique

In traditional fountain pens, the nib is generally fixed inside; traditional gel pens, signature pens and ballpoint pens are written by rotating balls, and traditional needle pens are written by swinging up and down a metal rod built into the pen needle. At present, the writing tool required by the general education writing class is mainly a pen. The fountain pen is a foreign writing tool produced in accordance with the writing of Western alphabets, and its expressiveness for writing Chinese characters is very limited. The more popular neutral pens not only do not have the writing effect of fountain pens and brushes, but are generally used as disposable pens. , wasteful and polluting the environment.

Gel pen, short for neutral ink ballpoint pen, originated in Japan and is a novel writing tool popular in East Asia. According to the type of pen tip, ink color, structure, etc., it can be divided into different types of gel pens, and you can choose according to your own needs. Gel pens have the advantages of both water pens and oil-based ballpoint pens. They have a comfortable writing feel, low ink viscosity, and appropriate lubricants are added. The viscosity of the writing medium is between water-based and oil-based, so it is smoother than ordinary oil-based ballpoint pens. An upgraded product of oil-based ballpoint pens. The existing fountain pens and center pens need to be added with ink or replaced to ensure the normal use of the pen, but most of these pens have a single structure, no new shape, and the length of the pen body is relatively fixed. Therefore, for today's young people, More creative and fresh writing tools are needed. Many gel pens are one-time use, that is, the ink in the pen tube is used up and scrapped, and the design life of the nib and the pen body far exceeds the life of the ink, which causes a great waste of the nib and the pen body.

SUMMARY OF THE INVENTION

The purpose of the present invention is to aim at the defects and deficiencies of the prior art, and to provide a fountain pen whose length can be freely adjusted for automatic filling. It can be directly discarded, and a new ink refill can be inserted, which can be used in an almost infinite cycle, which greatly improves the utilization efficiency of the refill and nib; and the length of this fountain pen can be adjusted freely and can be changed arbitrarily according to the needs of the user, so that the user can always keep Freshness; keep users sticky.

In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: it comprises a pen body 1, a plurality of ink cores 2, and a pen cap 3, and the plurality of ink cores 2 are successively plugged and connected to form an ink core rod 21, and the pen body 1 is plugged into the ink core rod 21.
