Gel pen plastic tube refill with metal head convenient to replace and install

Abstract

The invention discloses a gel pen plastic tube refill with a metal head convenient to replace and install, and relates to the technical field of replacement and installation of metal pen heads. The gel pen plastic tube refill comprises a workbench, a metal pen head clamping device, a refill fixing device and a water inlet pen head clamping and replacing device. The metal pen head clamping device is arranged on the outer surface of the top of the workbench, the refill fixing device is arranged on the outer surface of the right side of the workbench, and the water inlet pen head clamping and replacing device is movably connected to the outer surface of the right side of the top of the workbench in a lap joint mode. According to the gel pen plastic tube refill with the metal head convenient to replace and install, a pen tube penetrates through the interiors of arc-shaped attaching panels and extends into the metal pen head clamping device, a pressing block is pushed in a matched mode to enable a square sleeve shell to be attached to the surface of the pen tube, the two arc-shaped attaching panels conduct attaching and pressing on the surface of the pen tube, the characteristic that a pen head of a gel pen can be rapidly replaced and installed is achieved, the problem that the plastic pen tube is very likely to bend and deform during installation is solved, and the effect of carrying out extrusion protection on the surface of the pen tube is achieved.

Description

technical field [0001] The invention relates to the technical field of replacing and installing metal nibs, in particular to a gel pen plastic tube refill which is convenient for replacing and installing metal nibs. Background technique [0002] An accessory to a writing instrument, which can be replaced many times. A tube containing ink or ink in a ballpoint pen or fountain pen tube, with a metal nib at the front end, and a ball for writing is embedded in the nib. Also refers to the graphite strip in a pencil. , The pen refill is the rubber tube or suction water pipe in the pen tube. There are following problems at prior art: [0003] 1. The nib of the gel pen is relatively small. When installing and replacing, it is not easy to be clamped with one end of the pen tube, and the plastic pen tube is easy to cause bending deformation during installation; [0004] 2. The nib of the neutral nib needs to be closely connected to the barrel so that it will not fall off in later us...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a gel pen plastic tube refill that is easy to replace and install a metal head, one of the purposes is to have the characteristics of quickly replacing and installing the nib of the gel pen, and to solve the problem that the nib of the gel pen is relatively small. When installing and replacing, it is not easy to clamp with one end of the pen tube, and the plastic pen tube is easy to cause bending and deformation during installation; another purpose is to solve the problem of tight docking of the pen tube of the gel pen tip, causing the pen tip The problem that it is not easy to fall off from the pen tube is to achieve the effect of snapping and pulling the pen head to quickly fall off
