Abstract

The invention discloses a simple environment-friendly shifting pen. The relative positions of a front pen holder and a rear pen barrel are changed through sliding connection between the front pen holder and the rear pen barrel so that a refill tip can be exposed out of or retreat into the front pen holder, then the refill tip is maintained in the exposure position or the retreating position through a first fixing and holding mechanism and a second fixing and holding mechanism, and thus the purposes of using the environment-friendly shifting pen for writing and carrying the environment-friendly shifting pen conveniently are achieved. Due to the fact that the environment-friendly shifting pen is not provided with a pen cap or a spring structure of a traditional pen, the environment-friendly shifting pen is unlikely to be lost, and the production cost is low; in addition, the environment-friendly shifting pen has the advantages of being simple in structure and environmentally friendly.

Description

A kind of easy Environment-friendlypull pull pen

Technical field

The invention belongs to the technical field of writing implement, relate in particular to a kind of easy Environment-friendlypull pull pen.

Background technology

Pen common in the market comprises the pen of band cap and band spring, and during use, cap is generally placed on one side or is enclosed within a top, is easy to lose or cannot use because of the wearing and tearing of cap.Pen with spring requires height to pen core, and is easy to lose.The parts of cap or spring too increase production cost, and are unfavorable for environmental protection.

Summary of the invention

The object of this invention is to provide the simple easy Environment-friendlypull pull pen of a kind of structure, it does not have cap or spring structure, still can realize making the head of pen core to expose for write and the head of pen core is hidden when not using.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of easy Environment-friendlypull pull pen, comprise front penholder, rear pen container and have the pen core of pen core head, pen core plug-in card forms tight fit in rear pen container, and front penholder and rear pen container socket-connect, and front penholder and rear pen container are slidably connected; Be slidably connected by this, pen core head has the second place being hidden in primary importance in front penholder and exposing in penholder in the past.

On the basis of such scheme and as the preferred version of such scheme: described pen core forms tight fit by chuck plug-in card in rear pen container, and chuck is fixedly connected with rear pen container, and described chuck is continous way or segmentation structure.

On the basis of such scheme and as the preferred version of such scheme: described primary importance and the second place reach a kind of metastable state by the internal protrusion point of front penholder and the frictional force of reservoir shaft.

On the basis of such scheme and as the preferred version of such scheme: first fixing structure making pen core head remain on primary importance can be increased.

On the basis of such scheme and as the preferred version of such scheme: second of the described second place hold mechanism by the internal protrusion point of front penholder and the frictional force of reservoir shaft reach a kind of when writing front penholder and the metastable state of rear pen container.

On the basis of such scheme and as the preferred version of such scheme: described first fixing structure is made up of the first lug boss, the first protrusion, the second protrusion, described first lug boss is fixed in rear pen container, and described first protrusion, the second protrusion are fixed on front penholder.

On the basis of such scheme and as the preferred version of such scheme: after front penholder and rear pen container socket-connect, the first lug boss in rear pen container has also snapped in first protrusion on front penholder surface, is not drawn out easily.

On the basis of such scheme and as the preferred version of such scheme: front penholder in rear pen container slidably distance be equal to or greater than the length of the pen core head of pen core.

The present invention gives prominence to compared to existing technology and useful technique effect is:

?

Accompanying drawing illustrates:

Figure mono-is the front view at the rear pen container position of the embodiment of the present invention one

Figure bis-is the front views at the front penholder position of the embodiment of the present invention one

Figure tri-is the front views at the rear pen container position of the embodiment of the present invention two

Figure tetra-is the front views at the front penholder position of the embodiment of the present invention two

Concrete embodiment

Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1-figure

4, in easy Environment-friendlypull pull pen of the present invention, during to write, the direction of pen is to determine above-below direction.

Embodiment one:

As depicted in figs. 1 and 2, it illustrates the structure of the first embodiment of easy Environment-friendlypull pull pen of the present invention.As shown in Figures 1 and 2.During use, by rear pen container down by or front penholder is upwards pressed, make the first lug boss 6 slide into one end away from the first protrusion 3, now the pen core head of pen core is exposed at the outside of front penholder, for writing.The not used time, up pulled out by rear pen container or down pulled out by front penholder, making the first lug boss 6 slide into the below of the first protrusion 3, preferably, D equals or the length of pen core head slightly larger than pen core, and pen core head is hidden in front penholder 5.

Embodiment two:

As shown in Figure 3 and Figure 4, it illustrates the structure of the second embodiment of easy Environment-friendlypull pull pen of the present invention.As shown in Figures 3 and 4.During use, by rear pen container down by or front penholder is upwards pressed, make the first lug boss 6 slide into one end away from the first protrusion 3, now the pen core head of pen core is exposed at the outside of front penholder, for writing.The not used time, up pulled out by rear pen container or down pulled out by front penholder, making the first lug boss 6 slide into the below of the second protrusion 2, preferably, D equals or the length of pen core head slightly larger than pen core, and pen core head is hidden in front penholder 5.When needing to go out to carry or need to ensure that pen core can not expose, rear pen container can be retell and up pull out or front penholder is down pulled out, make the first lug boss 6 slide into the top of 2 of the second protrusion.

Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalence changes done according to structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.
