Abstract
The utility model is the pencil that a kind of novel lead for retractable pencil of writing and penholder Split assembled use, and it is made up of four parts: lead for retractable pencil, overcoat, penholder and rear seal-cover composition.The two ends of lead for retractable pencil are taper, and lead for retractable pencil by rotary sleeve, penholder is advanced, and compressing penholder front end is shunk, and lead for retractable pencil is locked, and lead for retractable pencil spacing hole is used for limiting the certain length that exposes of lead for retractable pencil and lead for retractable pencil is stablized.Penholder is hollow body, can place spare lead core.Rear seal-cover is rubber or ornament.It preserves the advantage of Wood pencil and propelling pencil, overcome their shortcoming, is good writing implement.
Description
The utility model relates to a kind ofly writes the pencil used with lead for retractable pencil and penholder Split assembled.
Pencil common in the market roughly can be divided into two classes: the first kind refers to the pencil of disposable consumption, and its penholder and pen core are consumed along with the use of pencil simultaneously.As common Wood pencil.The annual forest producing this pencil consumption of country is appreciable, and penholder is single use, can not reuse.From the lead for retractable pencil utilization rate of Wood-bar pencil, its practical efficiency is less than 17%, and most of lead for retractable pencil has in use all been reamed.Pen must be cut before this pencil uses at every turn and repair lead, waste time and energy.Equations of The Second Kind refers to the pencil that lead for retractable pencil penholder Split assembled uses.As propelling pencil, this kind of pencil complex structure, price is higher, and because lead for retractable pencil is comparatively thin, dynamics is inadequate, easily causes lead for retractable pencil to fracture, be unfavorable for that pupil writes during use, and it uses popularity rate well below common Wood pencil.
The utility model overcomes the weak point in above-mentioned existing pencil, proposes a kind of structure simple, novel pencil easy to use.
The utility model is made up of four parts: lead for retractable pencil, penholder, overcoat and rear seal-cover.Lead for retractable pencil two ends are its length of taper is 15-30 millimeter, and its diameter is greater than 1.5 millimeters.Lead for retractable pencil surface scribbles separation layer.Overcoat front end is circular cone hollow body with holes, is enclosed within the outside of penholder, and overcoat rear end is connected with penholder, and be connected threadably, overcoat rear end is negative thread.Penholder is hollow body, penholder there is pin thread, the front hole of overcoat is given prominence in front end with the penholder of opening, lead for retractable pencil inserts the front hole of pen, spacing hole on penholder is used for length that spacing lead for retractable pencil exposes and stable, rotary sleeve make penholder front wear one with the position of upper shed shrink locking or loosen lead for retractable pencil, the end of penholder is connected with rear seal-cover.To make dirty when nontoxic separation layer on lead for retractable pencil surface is and prevents from changing lead for retractable pencil finger.The hollow parts of penholder can be used for placing spare lead core.Rear seal-cover is rubber or ornament.
The utility model is rational in infrastructure, sturdy and durable, have the advantage of common Wood pencil and propelling pencil concurrently, the practical efficiency of its lead for retractable pencil reaches 30%, its penholder can produce with multiple material the various shape and pattern that consumer likes, and penholder can reuse, can think that country saves a large amount of timber, the use cost of pencil can be reduced again.It is the writing implement of the common Wood pencil of a kind of good replacement and propelling pencil.
