Description
Technical field:
The utility model relates to a kind of change-fountain pen head unit, more specifically to the quick change-fountain pen head unit of one.
Background technology:
The ball pen of viscosity between water-based and oiliness of writing medium is called gel ink pen, is the writing implement of a kind of novelty popular in the world at present.Gel ink pen has the advantage of fountain pen and ball pen concurrently, writes comfortable feel, and ink viscosity is lower, and increases the material of easily lubrication, thus more smooth than common oiliness ball pen, is the upgraded product of oiliness ball pen.The critical piece of gel ink pen is pen core, and after if pen core runs into and clashes (pen drops on the ground), pen core head has often just broken down, whole gel ink pen is made all to scrap, whole pen can only be thrown away, and to change nib be a very troublesome thing, if design a kind of can the device of quick-replaceable nib just can addressing this problem, so it is very useful for designing a kind of quick change-fountain pen head unit.
Utility model content:
The purpose of this utility model is exactly for the deficiencies in the prior art, and provides a kind of change-fountain pen head unit fast.It is simple that the utility model has structure, easy to use, pen core head is inserted in pen core positioning tube, two fixed claws are stretched in a shell, pen core head is aimed at pen core end, then firmly press toward next, pen core head just enters in pen core naturally, replacing pen core head is quick and convenient, and straight the connecing broken down so as not to pen core head is thrown away, and saves the advantage of ink.
Technology solution of the present utility model is as follows:
A kind of change-fountain pen head unit fast, comprise written stiff end and fixed claw, the quantity of described fixed claw is two, two fixed claws are fixed on the top of written stiff end, nib stiff end is back taper, nib stiff end inside center is fixed with a coil component spring, and coil component spring top is fixed with pen core positioning tube, is provided with a circle in-flanges bottom pen core positioning tube.
In technique scheme, described fixed claw lateral surface is fixed with a crushing block, and crushing block surface is provided with anti-slip veins bar, and fixed claw top is provided with a claw hook.
In technique scheme, the top of described pen core positioning tube exceeds the top of written stiff end.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, pen core head is inserted in pen core positioning tube, two fixed claws are stretched in a shell, pen core head is aimed at pen core end, then firmly press toward next, pen core head just enters in pen core naturally, replacing pen core head is quick and convenient, and straight the connecing broken down so as not to pen core head is thrown away, and saves ink.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is written stiff end complete section structural representation.
In figure: 10, written stiff end; 101, coil component spring; 102, pen core positioning tube; 1021, in-flanges; 20, fixed claw; 201, crushing block; 202, claw hook; 203, anti-slip veins bar.
Detailed description of the invention:
