Description

Variable-length formula ball pen

Technical field

The utility model relates to a kind of pen used in everyday, the variable-length formula ball pen that especially a kind of penholder length can be stretched.

Background technology

The pen of volume miniaturization carries and uses because of being convenient to people, can be used as mobile strap, key chain, decoration suspension member etc., and receive an acclaim in daily life.But ball pen has in the past just shortened penholder length, thus need be firmly more when actual writing, be not suitable for writing for a long time, especially all the more so for the bigger user of hand; The miniaturization ball pen of pen container has appearred again having afterwards, rear end with penholder during use inserts in the pen container, thereby play the effect that prolongs penholder, but cooperate insecure in use between pen container and the penholder, problems such as becoming flexible, come off appears, and when pen container is suspended on the article, the penholder use that can't match with pen container.

Summary of the invention

The variable-length formula ball pen that technical problem to be solved in the utility model provides a kind of reasonable in design, is easy to carry and writes.

The technical scheme in the invention for solving the above technical problem is: this variable-length formula ball pen comprises pen container, pen core and penholder, its design feature is also to be provided with nib, the outer wall of nib is provided with nib retaining head, described penholder by fixing penholder and in be provided with pen core movable penholder form, fixedly penholder and movable penholder form the stretching structure of antenna formula, movable penholder links to each other with nib, and the head of pen core exposes nib, fixedly the bottom of penholder is equipped with bonnet, and the inwall of pen container is provided with the pen container retaining head that is complementary with nib retaining head.

The diameter of fixedly penholder front opening described in the utility model is less than the race diameter of movable penholder rear end.

One end of pen container described in the utility model is provided with connecting ring, can be connected with attaching parts on the connecting ring.

The utility model compared with prior art, have following beneficial effect: 1, penholder is by fixedly penholder and movable penholder are formed, movable penholder is positioned at fixedly penholder, movable penholder can fixedly stretch in the penholder, and movable penholder stretches out fixedly penholder during use, the penholder elongation, the fixing penholder of movable penholder indentation when not using, penholder shortens, and is so not only not hard when writing, and is easy to carry again; 2, be respectively arranged with the nib retaining head and the pen container retaining head that match each other on nib and the pen container, in drawing fixedly during penholder, the end that movable penholder links to each other with fixing penholder stretches out fixedly penholder, and the end that it links to each other with nib is because the interaction of two retaining heads, still be positioned at pen container, when fixedly penholder is pulled out pen container fully, nib that links to each other with movable penholder and pen container just break away from fully, like this when the penholder drawing goes out pen container, movable penholder is fully from fixedly stretching out in the penholder, and penholder extends, that is to say, extracting penholder carries out simultaneously with the elongation penholder, settle at one go, therefore very easy to use; 3, can be connected with attaching parts such as lanyard on the connecting ring of pen container one end, so that pen is hung on user's neck or the article such as handbag, mobile phone, even pen container is suspended on the article, also can play the effect of elongation penholder, need not when writing to be used with pen container, both beautiful and practical.

The specific embodiment

Referring to Fig. 1, present embodiment includes pen container 50, pen core 40, nib 21 and penholder 10, and wherein penholder 10 is made up of fixedly penholder 30 and movable penholder 20, and fixedly penholder 30 and movable penholder 20 form the stretching structure of antenna formulas.

The fixing internal run-through of penholder 30, its front opening, the rear end is the fixing bottom of penholder 30, and the bottom is nested with bonnet 31, and this outer rear cover 31 fixed form such as also can take to bond or be threaded links to each other with fixing penholder 30.

Pen core 40 is positioned at movable penholder 20, and the front end of movable penholder 20 is bonded and fixed at nib 21, and the head of pen core 40 exposes nib 21, and the rear end of movable penholder 20 is positioned at the fixedly openend of penholder 30.Nib 21 also can adopt fixed form such as be threaded to link to each other with movable penholder 20 in addition.

In order not make movable penholder 20 from fixedly coming off in the penholder 30, fixedly the diameter of penholder 30 front openings is less than the race diameter of movable penholder 20 rear ends, and for the ease of drawing and installation, movable penholder 20 and fixedly the cross section outline of penholder 30 all have gradient.

Above structure can fixedly stretched movable penholder 20 in the penholder 30, thereby forms the stretching structure of antenna formula.

The outer wall of nib 21 is provided with nib retaining 22, the inwall of pen container 50 be provided with projection with nib retaining 22 a pen containers retaining that are complementary 52, when penholder 10 was positioned at pen container 50, because the interaction of pen container retaining 52 and nib retaining 22, nib 21 was connected together with pen container 50.

Simultaneously, outside pen container 50 can also be protected pen core head 41 and prevent that printing ink from revealing or being applied to.

Referring to Fig. 2, when not using, movable penholder 20 and fixedly penholder 30 all be positioned at pen container 50.

Referring to Fig. 3, during use, drawing is penholder 30 fixedly, at this moment the end that movable penholder 20 links to each other with fixing penholder 30 stretches out fixedly penholder 30, penholder 10 elongation, and the end that movable penholder 20 links to each other with nib 21 still is fixed in the pen container 50 because pen container retaining 52 and nib keep off an interaction of 22.

Referring to Fig. 4, when fixedly penholder 30 was pulled out pen container 50 fully, the nib 21 that links to each other with movable penholder 20 just broke away from fully with pen container 50, and at this moment movable penholder 20 is also fully from fixedly stretching out penholder 10 elongations in the penholder 30.So just reached and extracted the purpose that penholder 10 and elongation penholder 10 carry out simultaneously, that is to say penholder 10 elongations when extracting penholder 10, can write after extracting penholder 10, very convenient.

Penholder 10 extract behind the pen container 50 state as shown in Figure 5.

Referring to Fig. 6, Fig. 7, end at pen container 50 can be provided with connecting ring 55, can be connected with attaching parts 60 such as lanyard on the connecting ring 55, so just can pen be suspended on user's neck or the article such as handbag, mobile phone, the use that both had been easy to carry can be used as ornament again.

In addition, the utility model is not limited to the concrete structure of the foregoing description, as movable penholder and fixedly penholder can adopt other shapes, pen container retaining head can adopt other can with the nib retaining form of clamping mutually.In a word, protection domain of the present utility model is because of comprising those conspicuous to those skilled in the art conversion or substituting and remodeling.
