Abstract
The invention discloses an environment-friendly pencil which comprises a pencil body and an eraser. The environment-friendly pencil is characterized by further comprising paper skin or wood skin; a pencil holder is made of plant straw; a pencil lead is tenacious; the length of the paper skin or the wood skin is the sum of the length of the pencil body and the length of the cylindrical eraser; the paper skin or the wood skin is closely attached to the outside of the pencil body and the outside of the eraser; a partition plate is arranged between the pencil body and the eraser. The pencil is made of the plant straw, wood can be saved, the pencil lead is tenacious, the pencil is prevented from being dropped, both the pencil body and the eraser can be used up to the greatest extent, resources are saved, and environmental friendliness is achieved.
Description
Technical field
The invention belongs to pencil field, be specifically related to a kind of environment protection type pencil.
Background technology
The structure of traditional rubber tip pencil is that rubber and a kind of aluminium leather sheath of pencil connect, and the diameter after aluminium leather sheath connects is 0.8 centimetre, is highly 1.2 centimetres, and the rubber segment length be exposed has 10-20 millimeter, and rubber ratio very little, cannot meet a large amount of wiping amendment.During use, when the rubber wiping be exposed polishes time, rubber section or else erasable use under the stop of aluminium leather sheath of aluminium leather sheath wrapping portion, this section of rubber can be wasted usually.When wooden section of pencil is cut too in short-term, because aluminium leather sheath and rubber tip are too short, and the part that rubber tip is exposed is soft, aluminium leather sheath and rubber tip is short usually can not hold by hand, can only catch with thumb, forefinger and middle finger three finger tips and can not hold in the mode of holding a pen during use, use inconvenience, the length keeping when pencil is too short normally holding a pen cannot be regulated, be mostly also stay remaining certain length just to be thrown away, cause unnecessary waste.In prior art; there is the pencil of a kind of pen point casing and pen cap; pen cap is for the protection of nib; pen point casing is used for entangling rubber; but the pencil nib cover of this structure is regular length, usually made by hard materials such as plastics, production cost is high; use during rubber and also need pen point casing to take off, seem inconvenient.
In addition, timber is the precious resources of country, is also material in short supply, and how all trades and professions all save timber in research, seek substitute for wood, and general pencil adopts wood pen holder, and its material consumption timber is large, is unfavorable for environmental protection.Wood pencil processing and manufacturing process is more complicated, and pollute large, cost is high, and quality control is difficult, the less change of outward appearance.Children use or easily broke when playing, and pen core is write difficultly, and coloring is poor.
Summary of the invention
The object of the invention is to for above-mentioned Problems existing and deficiency, provide cheap, good springiness, not easy fracture, the erasing rubber pencil that the environmental protection of alternative timber can be cut.
To achieve these goals, present invention employs following technical scheme:
A kind of environment protection type pencil, comprise pencil and erasing rubber, it is characterized in that: also comprise leatheroid or wooden skin, the penholder of described pencil is manufactured by straw, the toughness pen core that pen core is, described leatheroid or wooden skin length are the length sums of pencil and cylinder erasing rubber, and described leatheroid or wooden skin are close to pencil and the outer body of erasing rubber, are provided with demarcation strip between described pencil body and erasing rubber.
Its proportioning of the formula of the above toughness pen core: graphite powder 50 parts, polystyrene 16 parts, polyethylene 9 parts, haloflex 3 parts, calcium stearate 3 parts, stearic amide 3 parts, clay 8 parts.
The above erasing rubber 1 and pencil length dimension are than being 1:3-1:1.
The above leatheroid or wooden skin 2 are close to pencil and erasing rubber 1 by gluing.
Beneficial effect of the present invention:
Pencil of the present invention uses straw manufacture, and can save timber, pen core is toughness pen core, shatter-resistant.And it is longer by saying that erasing rubber length is arranged, when pencil cutting too much only remains very short, and the leatheroid of erasing rubber section outer wrapping or wooden skin long enough, then the leatheroid of erasing rubber section outer wrapping or wooden micromicro are as hand-held use, facilitate user to continue to use pencil until use, avoid wasting pencil.When erasing rubber needs more uses, the leatheroid of erasing rubber section outer wrapping or wooden micromicro, can until use erasing rubber to cut, and no matter the present invention is that pencil section or erasing rubber can use to greatest extent, avoids waste, uses environment friendly convenient.
