Abstract

The invention discloses a gel pen plastic tube refill which is easy to replace and install a metal head, and relates to the technical field of replacing and installing a metal nib, including a workbench, a metal nib snap connector, a pen core fixing device and a water-inlet nib snap-fit ​​changer , the top outer surface of the workbench is provided with a metal nib clip connector, the right side outer surface of the workbench is provided with a refill fixing device, and the top right outer surface of the workbench is movably overlapped with The water inlet nib is snapped into the changer. In the present invention, the pen tube passes through the inside of the arc-shaped fitting panel and extends to the inside of the metal nib snap connector, and cooperates with pushing the pressing block to fit the square casing to the surface of the pen tube, and the two arc-shaped fitting panels are aligned with the can The surface of the pen tube is pressed and pressed, which has the characteristics of quick replacement and installation of the nib of the gel pen. It solves the problem that the plastic pen tube is easy to bend and deform during installation, and achieves the extrusion of the surface of the pen tube. protective effect.

Description

technical field [0001] The invention relates to the technical field of replacement and installation of metal pen heads, in particular to a plastic tube refill of a gel pen which is convenient for replacement and installation of metal heads. Background technique [0002] Accessories for writing instruments, which can be replaced many times, a tube with ink or ink in the tube of a ballpoint pen or fountain pen, a metal nib at the front, and a ball for writing embedded in the nib, also refers to the graphite strip in the pencil , the pen refill is a rubber tube or a suction hose in the pen tube. The following problems exist for the prior art: [0003] 1. The pen head of the gel pen is relatively small. When installing and replacing, it is not easy to connect with one end of the pen tube, and the plastic pen tube can easily cause bending and deformation problems during installation; [0004] 2. The neutral pen tip needs to be closely connected with the pen tube so that it will...
