Abstract
The pencil that the utility model provides a kind of rotary extension to use, described penholder is furnished with the nib of a rotatable adjusting refill expansion, the elliptic pencil-lead of spiral silking can be placed in the corresponding identical slotted eye with it in the middle of penholder, is provided with and the identical consistent spiral cylindrical void of elliptic pencil-lead spiral silking in the middle of nib.During use, can be by rotating nib the oval refill expansion by spiral silking, the nib that only needs thus to fine away is used, and reduces volume and cuts the wasting of resources that penholder causes.
Description
Technical field
The utility model relates to a kind of pencil, the pencil that a kind of rotary extension is used specifically.
Background technology
The various pencils that use now, be the structure of wood pen holder, during use, must cut penholder by volume could fine away pen core to use, and this traditional pencil both bothered in use, the wasting of resources that has caused again wood pen holder volume to cut, though there is in recent years the propelling pencil that plastic material is made, but due to tiny, cannot produce compared with macrostructure, also be subject in the use limitation, can only be as the small-sized use of writing.
Summary of the invention
The pencil that provides a kind of rotary extension to use is provided the purpose of this utility model, has both retained the handling characteristics of traditional pencil, has avoided again volume to cut the wasting of resources that penholder causes.
The utility model comprises penholder, the technical scheme adopting is: described penholder is furnished with the nib of a rotatable adjusting refill expansion, the elliptic pencil-lead of spiral silking can be placed in the corresponding identical slotted eye with it in the middle of penholder, is provided with and the identical consistent spiral cylindrical void of elliptic pencil-lead spiral silking in the middle of nib.
In technique scheme: the nib of rotatable adjusting refill expansion is sleeved on the light face swivel head of penholder by the pen cap being integrated.
The beneficial effects of the utility model are: owing to having adopted above-mentioned a kind of like this overall structure, during use, only need rotating nib, elliptic pencil-lead can be stretched out or shrinks, after stretching out, only nib need be cut and can use for sharp body or needed sharp body, during folding and unfolding, nib is shunk and can protect nib, in using continuously, only needing continuous rotation constantly will stretch out lead for retractable pencil fines away, having solved thus traditional pencil must cut penholder volume and could use the use causing to bother and waste resource problem, unusual science in design, the favourable minimizing wasting of resources and easy to use.
