Abstract

The utility model relates to a writing implement, specifically to a gel-ink pen with a replaceable nib, including a tubular penholder and a refill mounted in the penholder. A nib is equipped on the front end of the refill; a conical form penpoint is arranged on the front end of the penholder; a plug is disposed on the back end of the penholder; and the plug is a cylinder with external threads. The nib has external threads; the penpoint has internal threads and the nib and the penpoint are connected together through matching of internal and external screw threads thereon. In the gel-ink pen, the nib is directly equipped on the refill so that it is unnecessary to replace the nib when replacing the refill filled with printing ink and the nib is reused, thus avoiding waste; additionally, nibs with different types could be individually replaced, thus obtaining different writing effects. The pen has multiple functions.

Description

The gel ink pen of replaceable nib

Technical field

The utility model relates to a kind of writing implement, is a kind of gel ink pen of replaceable nib specifically.

Background technology

Gel ink pen is easy to use, is subjected to liking very much of student and white collar personage.The pen core of gel ink pen is disposable, will change whole pen core after printing ink uses up.Pen core adopts high-quality alloy material to make usually, and disposable use causes waste bigger.In addition,, have only a kind of width of stroke when writing, can not adapt to the requirement of multiple application for the pen core of fixing nib.

Summary of the invention

The purpose of this utility model provides the gel ink pen of a kind of environmental protection and energy saving, replaceable nib easy to use.

For achieving the above object, the utility model is by the following technical solutions:

The gel ink pen of replaceable nib described in the utility model comprise tubulose penholder, be installed in the pen core in the penholder, the front end of pen core is equipped with nib, the front end of penholder has cone shape nib, the rear end of penholder has plug, described plug is for having externally threaded cylinder, it is characterized in that: have external screw thread on the described nib, have internal thread on the nib, nib links together by threaded engagement with nib.

After adopting technique scheme, the gel ink pen of replaceable nib is directly installed on nib on the pen core, thereby needn't change nib when changing the pen core that printing ink is housed, and nib can be reused, and has avoided waste; In addition, can also follow separately and change the nib of different model, thereby obtain different writing effects, accomplish to use one more.
