Abstract

The utility model relates to a ball-point pen capable of adjusting the refill and using refills of different lengths. The pen cap fits over the end of the pen barrel. Advantages: firstly, it can be used for ballpoint pen refills of different lengths; secondly, its structural design is novel, unique, simple, practical and low in manufacturing cost.

Description

Can use the ball pen of different length pen core

Technical field

The utility model relates to a kind of ball pen that can regulate the used different length pen core of pen core, belongs to ball pen and makes the field.

Background technology

Often can't buy compatible with it pen core after existing ball pen on the market, original pen core use up, can't buy pen core, cause ball pen to use.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design a kind of ball pen that can use the different length pen core.

Design: to achieve these goals.1, the design of penholder shaft draw-in groove reaches the design of the pen core regulating block that mates with draw-in groove, is one of technical characterictic of the present utility model.The purpose of doing like this is: the pen core of different length can be positioned by the pen core regulating block, guarantee the normal use of ball pen.2, draw-in groove extends to the centre of penholder from the penholder end of ball pen always, is two of feature of the present utility model.The purpose of doing like this is: draw-in groove length is long more, and the scope of applicable pen core is big more, that is to say, because the length of draw-in groove is long, the pen core regulating block can be regulated easily by draw-in groove, to adapt to the ball pen of different length.

Technical scheme: can use the ball pen of different length pen core, it comprises ball pen, has draw-in groove on ballpoint holder 1 shaft, the pen core regulating block is positioned at the penholder chamber and the pen core regulating block has a boss, and the pen cap is enclosed within the penholder end.

The utility model is compared with background technology, and the one, can be suitable for the ball pen of different length; The 2nd, structural design novelty, uniqueness, simple, practical, low cost of manufacture.

Description of drawings

Fig. 1 is the structural representation that can use the ball pen of different length pen core.

The specific embodiment:

Embodiment 1: with reference to Fig. 1, can use the ball pen of different length pen core, it comprises ball pen, have draw-in groove 2 on ballpoint holder 1 shaft, pen core regulating block 3 is positioned at the penholder chamber and pen core regulating block 3 has a boss 5, the pen cap 4 is enclosed within penholder 1 end, and draw-in groove 2 extends to the centre of penholder always from the end of penholder.That is to say that by draw-in groove 2, boss 5 and pen core regulating block 3, just can use the ball pen of different length, wherein draw-in groove 2 extends to penholder 1 centre position from the end of ballpoint holder always, end is entangled by the pen cap 4.Draw-in groove 2 and boss 5 can fasten pen core regulating block 3, and pen core regulating block 3 can move in handwriting 1.

What need understand is; though above-mentioned fact Example is to the utility model detailed text description of contrasting; but these text descriptions; it is simple description to the utility model mentality of designing; rather than to the restriction of mentality of designing of the present utility model; any combination, increase or modification that is no more than the utility model mentality of designing all falls in the protection domain of the present utility model.
