Abstract

The utility model discloses a pressing pen, comprising a pen shaft, a pen clip, a pen refill, and a spring; a pressing head is arranged in the pen shaft near the end of the pen clip; a rotation wheel is arranged below the pressing head in the pen shaft; the rotation wheel is composed of two hollow cylinder-shaped sections; the outer surface of the first section is provided with two groups of protruding regularly at different height; the outer surface of the second section is provided with a protruding ring of a concave-convex shape; the pressing is of a cylinder shape with one sealed end which is the pressing operation part, while the other end is of a concave-convex shape matching the protruding ring; a third protruding is arranged on the outer surface near the end which is similar to a sawtooth shape; a plurality of protruding parts of ladder shapes are arranged in the same direction on the inner surface of the pen shaft near the pressing head; bayonets are arranged between two protruding parts; besides, the holding place of the pen clip is of a hollow structure, and the holding place matches another group of protruding parts on the rotation wheel through the opening of the pen shaft. The utility model can effectively avoid the trouble that the pen refill is left outside the point cover and the cloth is dirt.

Description

A kind of improved pressing pen

Technical field

The utility model relates to a kind of improved pressing pen.

Background technology

The pressing type pen of general structure is conveniently to use the popular welcome as consumers in general.But there is the place of a not hommization in the pressing pen of general structure, forget nib is retracted in the sharp trepanning after we use, and when penholder gone into pocket, ink will pollution clothes.

Summary of the invention

For overcoming this defective, the utility model proposes a kind of pressing type pen that improves structure, by with the serial verb construction on the clamping part of pen clip and the runner that drives pen core, when the user lifts clamping part and inserts pocket, pen core is shunk back get back to penholder inside, thereby avoided the pollution of ink.

In order to realize the foregoing invention purpose, the utility model provides a kind of improved pressing pen, comprise penholder, the pen clip that is connected with described pen arm end, be arranged on the pen core in the penholder, and the spring that is set in the nearly writing end of described pen core place, in the penholder of the end of nearly pen clip, be provided with one and press head, it is characterized in that, describedly in described penholder be provided with a runner below pressing head, described runner divides two sections one that roughly are hollow cylindrical to form, wherein differing heights place rule is provided with two groups of projections on first section the external cylindrical surface, also be provided with the bulge loop of a concave-convex surface on second section the external cylindrical surface, the described head of pressing roughly is the cylindrical of end sealing, and wherein blind end is as the pressing operating position, and the other end is cooperate with described bulge loop concavo-convex, on the external cylindrical surface of nearly zigzag end, be provided with the 3rd group of projection equally; On the inner cylinder face of the penholder of closely pressing head, the equidirectional projection that is provided with some trapezoidal shapes is at one bayonet socket of formation between any two of projection; In addition, the clamping part of pen clip forms hollow structure, and described clamping part holds by the opening on the described penholder and another group projection on the runner.

Reasonable is that the concavo-convex of described bulge loop and the abutting end of pressing head is zigzag.

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

Fig. 1 is the partial sectional view of the utility model pressing pen;

Fig. 2 is a runner and press the decomposing schematic representation of head in the penholder of Fig. 1;

Fig. 3 is the structural representation of penholder among Fig. 1;

Fig. 4 is the cutaway view of penholder among Fig. 3.

The specific embodiment

Fig. 1 has provided partial sectional view of the present utility model, shown pressing pen comprises penholder 1, the pen clip 2 that is connected with penholder 1 end, is arranged on the pen core 3 in the penholder 1, and the spring 4 that is set in pen core 3 nearly writing end places, in the penholder 1 of the end of nearly pen clip 2, be provided with one and press 5.

Be provided with a runner 6 below in penholder 1, pressing 5, this runner roughly was two section 61,62 one composition of hollow cylindrical in 6 minutes, two sections circumference directly has certain difference, wherein differing heights place rule is provided with two groups of projections 611,612 on one section 61 the external cylindrical surface, also is provided with the bulge loop 621 of an indention on the external cylindrical surface of another section 62.Press 5 and roughly be the cylindrical of end sealing, wherein blind end is as the pressing operating position, and the other end is the zigzag fashion that cooperates with bulge loop 621, on the external cylindrical surface of near zigzag end, is provided with the 3rd group of projection 51 equally.

Investigate the inside of penholder 1 again, closely pressing on the inner cylinder face of 5 penholder 1, the equidirectional projection 11 that is provided with some trapezoidal shapes is at one bayonet socket 111 of formation between any two of projection 11.

In addition, the clamping part 21 of pen clip 2 forms hollow structure, and this clamping part 21 holds by another group projection 611 on opening on the penholder 1 12 and the runner 6.

During installation, runner shown in Figure 26 is inserted by the lower end of penholder shown in Figure 31, one group of projection 612 on the runner 6 slips in the bayonet socket 111 along trapezoidal protruding 11 hypotenuse of penholder 1 inner cylinder face, press 5 a lower end insertion from pen clip 2, penholder 1 chucking that to pack into then and press a pen clip 2 of 5 and the runner 6 of packing into, one end of pen core 2 is inserted the cylindrical hollow part of runner 6, behind the sheathed spring 4 of the writing end of pen core 2 the lower end penholder is screwed.

During use, pressing presses 5, the writing end of pen core 2 exposes, when the user goes into pocket with penholder, can pull open the clamping part 21 of pen clip 2, clamping part 21 is in case break away from projection 611 on the runner 6, wholely presses 5, runner 6, pen core 2 will move under spring action, pen core 3 is retracted in the point cover 7, prevent from effectively to forget in the pen core 2 retractions point cover 7 and the unhappy thing of pollution clothes takes place.In addition, this a pen has also kept traditional pressing pen and presses and press head, the function of nib retraction.

More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
