Abstract

The invention discloses a gel pen with a replaceable refill and a pulling and installing tool, and relates to the technical field of gel pens. The gel pen comprises a replacement mechanism, a connecting mechanism is fixedly connected to the upper position of the surface of the replacement mechanism, a detection mechanism is fixedly connected to the top of the replacement mechanism, and the replacement mechanism comprises two half shells; and a friction layer is fixedly connected to the lower position of the surface of each half shell, the middle positions of the two half shells are fixedly connected through the connecting mechanism, a pen head is fixedly connected to the bottoms of the half shells, and a spring is fixedly connected to the inner side face of the pen head. According to the gel pen with the replaceable refill and the pulling and installing tool, through cooperative use of the replacement mechanism, the connecting mechanism, the detection mechanism, an extruding mechanism and other mechanisms, the problems that how to replace the refill of the gel pen without pulling out a pen cap on the upper portion with great effort and how to replace the refill with the pulling and installing tool are solved.

Description

technical field [0001] The invention relates to the technical field of gel pens, in particular to a gel pen with a replaceable refill and a pulling tool. Background technique [0002] Gel pen, the abbreviation of neutral ink ballpoint pen, is a novel writing tool popular in East Asia. It can be divided into different types of gel pens according to the type of pen head, ink color and structure. The advantages of pens and oil-based ballpoint pens, comfortable writing, low ink viscosity, and adding appropriate lubricants, the viscosity of the writing medium is between water and oil, so it is smoother than ordinary oil-based ballpoint pens. It is an upgraded product of oil-based ballpoint pens . Based on the above description, the inventors found that existing gel pens and unplugging tools mainly have the following deficiencies, such as: [0003] How to replace the refill of the gel pen without pulling out the upper cap, and how to use the pull-out tool to replace the refill. ...
