Abstract

The utility model discloses a novel propelling pencil including a lower pencil holder, an upper pencil holder, a pencil cap and a central shaft. The novel propelling pencil is characterized in that the central shaft comprises an entirely threaded screw, a prism block which is fixedly connected to the upper end of the screw and has a polygonal cross section, a pencil refill joint fixedly connected with the lower end of the screw, and a polygonal nut correspondingly sleeved on the screw. Carbon refill used in the propelling pencil is relatively thick, and conveyed out smoothly, so that the carbon refill can not be easily broken. Moreover, the propelling pencil is stable in structure, and easy and convenient for use. Compared with a conventional propelling pencil, the propelling pencil is more convenient for carrying around.

Description

A kind of new type auto pencil

Technical field

The utility model belongs to the stationery field, more specifically relates to a kind of new type auto pencil.

Background technology

Writing the pencil word now all is with pencil or propelling pencil, and wooden pencil needs constantly cutting normally to use in the time of not only can wasting resource but also use greatly, not only waste but also bother.For the drawback that overcomes pencil has been invented propelling pencil; Yet the adjusting of the carbon core of propelling pencil now is to lean on the internal structure of propelling pencil that handling up of carbon core accomplished; The action of carbon core is bigger because the carbon core that structural limitations is used needs very thin and propelling pencil is handled up; Be easy to the carbon core is fractureed, be easy to damage and not portable and the structure of the carbon core of handling up is also insecure.

The utility model content

In order to address the above problem, the purpose of the utility model is to provide a kind of new type auto pencil, the firm propelling pencil easy to use of a kind of structure.

For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of new type auto pencil; This propelling pencil comprises following pen container, goes up pen container, the cap for brush and central shaft; It is characterized in that central shaft comprises the screwed screw mandrel of entire body, be fixedly connected with screw mandrel upper end and the cross section is polygonal prism block, the pen core joint that is fixedly connected with the screw mandrel lower end, the corresponding polygon nut that is set on the screw mandrel.

More excellent, said pen container down upper end is provided with and the corresponding groove of nut, and nut embeds in the groove, is rotationally connected between last pen container and following pen container and relatively rotates Shi Buhui to produce pen container relative displacement longitudinally.

More excellent, the interior hole shape of said upward pen container is corresponding with the prism block shape, and prism block embeds in the endoporus of going up pen container and can move up and down.

More excellent, the said cap for brush is connected in the upper end of pen container.

More excellent, said pen core joint comprises shell and rubber cushion, the rubber cushion center is provided with circular hole.

After adopting technique scheme, its beneficial effect is: the carbon core that this propelling pencil uses is thick and carbon core output change is mild, and not frangible carbon core, and this automatic pencil structure is firm, easy to use, compares existing propelling pencil and is more convenient for carrying.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Extremely shown in Figure 5 like Fig. 1; A kind of new type auto pencil; This propelling pencil comprises down pen container 1, goes up pen container 2, the cap for brush 3 and central shaft 4, and central shaft 4 comprises the screwed screw mandrel of entire body 41, be polygonal prism block 42, the pen core joint 43 that is fixedly connected with screw mandrel 41 lower ends, the corresponding polygonal nut 44 that is set on the screw mandrel 41 with fixed connection of screw mandrel 41 upper ends and cross section.Following pen container 1 upper end is provided with and nut 44 corresponding grooves, and nut 44 embeds in the groove, and

last pen container

2 and 1 of following pen container are rotationally connected and relatively rotate Shi Buhui and produce pen container relative displacement longitudinally.The interior hole shape of last pen container 2 is corresponding with prism block 42 shapes, and prism block 42 embeds in the endoporus of going up pen container 2 and can move up and down.The cap for brush 3 is connected in the upper end of pen container 2.Pen core joint 43 comprises shell and rubber cushion, and the rubber cushion center is provided with circular hole.

Principle and beneficial effect: during use; Earlier with in the circular hole in the carbon core 5 embedding pen core joints 43; Central shaft 4 inserts in the pen container afterwards; An end that has a carbon core 5 inserts pen container 1 down and nut 44 is embedded in the groove of pen container 1 upper end down, and prism block 42 embeds in the endoporus of going up pen container 2, following pen container 1 and last pen container 2 mutual sockets.Arrest pen container 2 or the cap for brush 3 and rotate down pen container 1 or arrest play pen container 1 and rotate and go up pen container 2, just can make start writing tube 1 and relative rotation of 2 generations of last pen container.Because prism block 42 embeds in the endoporus of going up pen container 2; When rotation relatively took place, it was static to look down pen container 1, and whom prism block 42 go up 41 rotations of pen container 2 rotating band movable wire bars with; Nut 44 is fixed on down on the pen container 1, stretches out and indentation so screw mandrel 41 moves up and down and drive carbon core 5 with last pen container 2 rotations.The carbon core 5 that this propelling pencil uses is thick and the 5 output changes of carbon core are mild, and not frangible carbon core 5, and this automatic pencil structure is firm, easy to use, compares existing propelling pencil and is more convenient for carrying.

Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
