Abstract

The utility model provides a conveniently change ballpoint of refill, includes the refill and the pen socket, the pen socket includes half left one, the right side half one and torsion spring, has all offered on the opposite face that half one on this left side and the right side are half one to be used for installing the groove is erected in the bar of refill, and the inner wall that the groove was erected in these two bars has all been seted up and has been write horizontal bayonet socket and accomodate horizontal bayonet socket, and separated around should writing horizontal bayonet socket and accomodating horizontal bayonet socket and arrange, the radius expansion portion that is equipped with and writes horizontal bayonet socket on the refill and accomodate horizontal bayonet socket homogeneous phase adaptation, form the activity space of a V style of calligraphy between the afterbody opposite face that half one on a left side and the right side are half one, torsion spring installs in a left side half one and the right side between half one to be located the activity space under. This ballpoint structural design is novel, and the practicality is strong, and it is convenient to change the refill.

Description

A kind of ball pen being convenient for changing pen core

Technical field

The utility model relates to family expenses daily writing articles for use, specifically refers to a kind of ball pen being convenient for changing pen core.

Background technology

Pen, it is a great invention of the mankind, be for the instrument write or paint, how will be with coloured solid or liquid (ink) on paper or the drafting of other surfaces of solids word, symbol or picture by nib, and also have and utilize the hardness of solid nib to write picture pencil and charcoal pencil.

For ball pen, it is also known as ballpoint pen, is to use dry consistence ink, relies on the upper steel ball freely rotated of nib to bring out transcription to a kind of writing implement on paper.It has non-leakage, not affect by climate and writing time is longer, without the need to often pouring into the advantages such as ink, and price is cheaper, is the writing implement being in fashion the world in the last few years the most.Existing ball pen wide variety, as band pen cap type ball pen, it needs the cap for brush, adds cost of manufacture, and the cap for brush is easily lost; For another example push type ball pen, its internal structure is complicated, parts are many, cost of manufacture is high.It is cumbersome all to there is refill in these two kinds of ball pens above-mentioned, needs the problem rotated.

Utility model content

The utility model provides a kind of ball pen being convenient for changing pen core, and it is desirable that its main purpose is to overcome existing ball-point pen structure design portion, changes the pen core also shortcoming such as inconvenient.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of ball pen being convenient for changing pen core, comprise pen core and the pen cap, the described pen cap comprises left side, right-hand part and torsionspring, the opposite face of this left side and right-hand part all offers the bar shaped vertical slot for installing described pen core, the inwall of these two bar shaped vertical slots all offers writes horizontal bayonet socket and the horizontal bayonet socket of storage, this writes before and after horizontal bayonet socket and the horizontal bayonet socket of storage arranged apart, described pen core is provided with and writes horizontal bayonet socket and receive all suitable increasing radius portion of horizontal bayonet socket, the activity space of a V-shape is formed between the afterbody opposite face of described left side and right-hand part, described torsionspring is installed between left side and right-hand part, and be positioned at immediately below activity space.

The opposite face of described left side and right-hand part all offers a horizontal port, described torsionspring is laterally installed in two horizontal ports.

The end lateral wall of described left side and right-hand part all scabbles formation one hand grip portion.

Described hand grip portion offers hanging hole.

From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages: this ball-point pen structure is novel in design, practical, changes pen core convenient, namely pinches out hand grip portion, can follow change-fountain pen core fast.When writing, hand grip portion is pinched with hand, make that left side described in it is relative with right-hand part opens, write in horizontal bayonet socket by corresponding being installed in increasing radius portion of pen core, such ball pen just can be write, when not writing, again pinch hand grip portion with hand, make that left side described in it is relative with right-hand part opens, corresponding for the increasing radius portion of pen core is installed in the horizontal bayonet socket of storage, the nib of such ball pen is just in collapsed state, without the need to the cap for brush.
