Technical Field

The utility model relates to a study stationery field, in particular to superfine gel pen.

Background

Pens are one kind of stationery and are seen everywhere in daily life. The pen in the current market generally comprises a hollow cylindrical pen holder and a pen core, an inner cavity is formed in the pen holder, the pen core consists of a pen point, a pen core cavity and a pen core fastening ring, after the pen core is placed into the inner cavity of the pen holder, the pen core fastening ring can abut against a pen nozzle at the lower end of the pen holder, then a pen head cover is screwed on the upper end of the pen holder, and the pen core is limited by combining the pen head cover and the pen nozzle, so that the pen core is prevented from falling out.

After the refill is consumed, a user needs to buy a new refill again; however, the types of the refills on the existing market are very many, the refills of various brands are different in length, and the length of the refill is limited by the length of the inner cavity of the pen holder; if the length of the pen core is too long, the pen point cover cannot be covered; if the length of the pen core is too short, the pen core placed in the inner cavity of the pen holder cannot abut against the pen head cover and can shake up and down, so that a user cannot write;

therefore, how to select a pen core matched with the gel ink pen currently in use is very important. However, the existing users need to spend a long time to verify matching when selecting the pen refills, which is not only troublesome and high in time cost, but also can be idle or even discarded in case of buying wrong pen refills, thereby causing resource waste.

SUMMERY OF THE UTILITY MODEL
