The pen refill transmission part is further provided with a manual part extending out of the pen holder, the manual part is used for driving the pen refill transmission part to slide along the pen holder, the pen refill transmission part is used for driving the gel pen refill to extend out or retract from the pen point of the pen holder, and the transmission part limiting structure is used for limiting the pen refill transmission part. And the gel pen refill is kept in a state of extending out of the pen point or retracting into the pen point. By applying the gel pen, the dual-color or multi-color gel pen can be realized by adopting the universal gel pen replacement refill, a replacement refill with a special design structure does not need to be adopted, and the gel pen is convenient to use.

Description

technical field [0001] The invention relates to the technical field of stationery, more specifically to a gel pen. Background technique [0002] Roller ball pens, the abbreviation of neutral ink ballpoint pens, have the advantages of both fountain pens and oily ballpoint pens. The writing feels comfortable, the ink viscosity is low, and the substance that is easy to lubricate is added. The viscosity of the writing medium is between water and oil. It is between oily, so it is smoother than ordinary oily ballpoint pens, and it is an upgraded product of oily ballpoint pens. Oil-based ballpoint pens can be made into multi-color pens. Each color of the oil-based pen core is sleeved with a spring. A sliding piece is arranged in the groove, and the sliding piece is in one-to-one correspondence with the tail ends of the oily pen cores of each color, and the oily pen core of the corresponding color can be cored out along the nib portion of the pen holder by pressing the sliding piec...

AI Technical Summary

Problems solved by technology

The general-purpose gel pen refill is thicker than the oil-based refill, the surface is smooth and there is no raised structure, the spring cannot be clamped, and the structure of the traditional multi-color oil-based ballpoint pen cannot be used, so the general-purpose gel pen refill should be pressed Dynamic gel pens are all single-core gel pens, which cannot be freely converted between dual-core or multi-core
