Description

Propelling pencil

Technical field

The utility model relates to a kind of propelling pencil, belongs to field of stationery.

Background technology

Current existence two kinds of pencils, wooden and automatically.Wood pencil uses inconvenience, and waste resource, existing propelling pencil complex process, price, and cored trouble, easily disconnected core, uses inconvenience.

Utility model content

For above-mentioned prior art Problems existing, the utility model provides a kind of propelling pencil, while saving resource, easily processes, with low cost, and pen core not frangibility, conveniently change core, easy to use.

To achieve these goals, the pencil main body of propelling pencil described in this propelling pencil comprises pen core clamping part and for advancing the turn-knob portion of described pen core clamping part;

Described pen core clamping part offers the pen core draw-in groove for clamping pen core;

On the rotatable shaft of a writing brush being connected to pencil main body in described turn-knob portion.

Described turn-knob portion arranges internal thread and cooperatively interacts with the external screw thread that arranges on described pen core clamping part.

Described turn-knob portion and pen core clamping part have more piece respectively, and single-unit turn-knob portion is shorter in length than single-unit pen core clamping part, and between adjacent two turn-knob portions, the distance of the shaft of a writing brush is slightly less than the length of single-unit pen core clamping part.

The cylinder of described pen core clamping part offers plane, and between described turn-knob portion, the plane matched with described plane is offered in shaft of a writing brush inside, and the outer wall subscript that the often joint shaft of a writing brush between described turn-knob portion offers plane is provided with alignment line.

Described pencil main body is all made of plastics.

Compared with prior art, this propelling pencil adopts the female knob knob propelling of band with the mode of externally threaded pen core clamping part, achieves the effect of propelling pencil, while saving resource, easily process, with low cost, and pen core not frangibility, conveniently change core, easy to use.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, the pencil main body 1 of this propelling pencil is comprised pen core clamping part 3 and for advancing the turn-knob portion 2 of described pen core clamping part 3, is screwed the mode of pen core clamping part 3 by turn-knob portion 2, advances pen core clamping part 3, realizes the effect of propelling pencil; Described pen core clamping part 3 offers the pen core draw-in groove 4 for clamping pen core 5; On the rotatable shaft of a writing brush being connected to pencil main body 1 in described turn-knob portion 2, ensure that screwing of turn-knob portion 2 is smooth and easy.

Further, described turn-knob portion 2 arranges internal thread and cooperatively interacts with the external screw thread that arranges on described pen core clamping part 3.The propelling of pen core clamping part 3 is realized by the mode of screwed.Turn-knob portion 2 on Propelling pencil with sharpener in cap main body 1 shaft of a writing brush, screwed the external screw thread driven on pen core clamping part 3 by the internal thread in turn-knob portion 2, realize the propelling of pen core clamping part 3, according to the needs using length, select the length exposing pen core 5, and then achieve the function of propelling pencil.

Further, described turn-knob portion 2 and pen core clamping part 3 have more piece respectively, easy to process, are easy to realize, easy to use.Single-unit turn-knob portion 2 is shorter in length than single-unit pen core clamping part 3, and such pen core clamping part 3 can some be in the shaft of a writing brush Inner of pencil main body 1 all the time, and then can not rotate with the rotation in turn-knob portion 2; Between adjacent two turn-knob portions 2, the distance of the shaft of a writing brush is slightly less than the length of single-unit pen core clamping part 3, so in use, when pen core clamping part 3 is about to depart from a upper turn-knob portion 2, and then can continue to be snapped to next turn-knob portion 2, ensure continuing to advance under the driving in next turn-knob portion 2.

Further, the cylinder of described pen core clamping part 3 offers plane 31, between described turn-knob portion 2, the plane matched with described plane 31 is offered in shaft of a writing brush inside, and the outer wall subscript that the often joint shaft of a writing brush between described turn-knob portion 2 offers plane is provided with alignment line 32.This ensure that pen core clamping part 3 is when being about to enter next joint shaft of a writing brush, alignment line 32 on the upper and lower shaft of a writing brush is alignd, in a line states, can ensure that the orientation of next joint shaft of a writing brush is identical with the orientation residing for a upper joint shaft of a writing brush, and then avoid when screwing turn-knob portion 2, pen core clamping part 3 occurs and that cannot advance phenomenon motionless because of stuck turn ensure that screwing of turn-knob portion 2 and making smooth advances of pen core clamping part 3.

Further, described pencil main body 1 is all made of plastics, with low cost, is convenient to processing.

After pen core 5 uses, nib can be taken off and take out pen core clamping part 3, residual pen core 5 is taken out from the pen core draw-in groove 4 pen core clamping part 3, change new pen core 5 and put into pen core draw-in groove 4, open the bonnet 6 of pencil main body 1, again the pen core clamping part 3 finished changing is put into, repeat above-mentioned steps, can continue to use.

While this propelling pencil saving resource, easily process, with low cost, and pen core not frangibility, conveniently change core, easy to use.
