Description

The flexible automatically pen of entertaining

Technical field:

The utility model relates to the stationery technical field, refers in particular to the flexible automatically pen of a kind of entertaining.

Background technology:

As a tool of writing implement, it is bringing into play irreplaceable effect in daily life.But we can see also anyway a tool now changes, and its structure is always similar, lack interesting.Though there is some tool to portray cartoon or animal-shaped at present on penholder, it does not break away from the design concept of traditional pen tool still based on penholder.

In addition, stretching structure too complex in traditional flexible automatically pen causes product to develop to miniaturization.

The utility model content:

Technical problem to be solved in the utility model is exactly the deficiency that overcomes existing product, and a kind of interesting, flexible automatically pen of the simple entertaining of stretching structure that has is provided.

For solving above-mentioned technical problem, the utility model has adopted following technical scheme: it comprises the bar cover and is installed on the interior pen core of bar cover, the bar cover is fastened mutually by left and right sides housing and forms, be arranged with spring on the pen core, also be provided with by a contact pressing piece in bar cover, an end of pen core is connected on the contact pressing piece, is formed with a shell fragment in a side of contact pressing piece, an outstanding knob of fixing on the shell fragment puts the chute of being offered by bar and extends to outside the bar cover, is provided with stuck point in the chute inboard.

The described two ends that are sheathed on the spring on the pen core are pressed on respectively on the baffle plate that is provided with in contact pressing piece and the bar cover.

Described contact pressing piece comprises shell fragment and adapter sleeve, and pen core one end is inserted in the adapter sleeve, becomes " L " shape with the integrated shell fragment of adapter sleeve, promptly is formed with compression stroke between shell fragment and the adapter sleeve.

The connected mode that adopts axis hole to fasten between the left and right sides housing of described bar cover.

After the utility model adopts technique scheme, designs simplification with automatic extending-contracting apparatus, so just can make the volume-diminished of product, manufacture small-sized the tool that has interest, for example the utility model be combined with trinket and just can form a tool with decoration, toy effect.In a word, the utility model not only has the writing function that the conventional pen tool is had, and it also can be used as a kind of trinket or toy supplies to admire after user's study and work, to alleviate the pressure of study or work, increase the interest of product, and make product have more the attraction.

The specific embodiment:

See accompanying

drawing

1,2,3, bar of the present utility model cover 1 is made of left and right sides housing 11,12.Adopt the connected mode of axis hole engaging in the utility model between the left and right sides housing 11,12, promptly left shell 11 is provided with a plurality of card posts 110, offers the hole clipping 120 corresponding with blocking post 110 on right shell body 12.Left and right sides housing 11,12 fastens by engaging mutually between card post 110 and the hole clipping 120.In bar cover 1, be formed with the cavity of a ccontaining pen core 2 and contact pressing piece 3.In order to make the utility model have more interest, bar cover 1 be shaped to patterns such as cartoon, animal, so just a tool is planted similar jewelry therewith to combine, it has more interest.

See Fig. 4,5,6, pen core 2 is positioned at the cavity of cutting ferrule 1, and its end can be stretched out by the opening of cutting ferrule 1 end.Also be provided with by a contact pressing piece 3 in the bar cover 1, this contact pressing piece 3 comprises shell fragment 31 and adapter sleeve 30, and pen core 2 one ends are inserted in the adapter sleeve 30, with 31 one-tenth " L " shapes of adapter sleeve 30 integrated shell fragments, promptly are formed with compression stroke 33 between shell fragment 31 and the adapter sleeve 32.Be fixed with an outstanding knob 32 on the shell fragment 31, this knob 32 is extended to outside the bar cover 1 by the chute of being offered on the bar cover 1 10, is provided with stuck point 13 in chute 10 inboards.Be arranged with spring 4 on the pen core 2, the two ends that are sheathed on the spring 4 on the pen core 2 are pressed on respectively on the baffle plate 14 that is provided with in contact pressing piece 3 and the bar cover 1.Pen core 2 and contact pressing piece 3 just have the trend of inside contraction under the elastic force effect of spring 4 like this.

The both sides of chute 10 recited above is respectively arranged with stuck point 13, and a stuck point 13 promptly is set respectively on left shell 11 and right shell body 12.

The utility model is not when using, and spring 4 promotes contact pressing piece 3 drive pen cores 2 and contracts to bar cover 1.As promote knob 32 on the contact pressing piece 3, then contact pressing piece 3 compression springs 4 are stretched out by bar cover 1 to promote pen core 2.After the end of the shell fragment on the contact pressing piece 3 31 is crossed stuck point 13, stop to promote knob 32, this moment, the two ends, the left and right sides 311,312 at top of shell fragment 31 were pressed on respectively on the stuck point 13 on the left and right sides housing 11,12, and pen core 2 just is defined like this, and the user can use a tool to write.When not in use, as long as press down knob 32, make the two ends, the left and right sides 311,312 at the top of shell fragment 31 break away from the stuck point 13 that it compressed, this moment, contact pressing piece 3 restored the beginning state next time in the elastic force effect of spring 4, and pen core 2 is also driven in the withdrawal bar cover 1.
