The utility model is characterized in that the exoperidium is provided with paper which has definite thickness and shape, oblique veins which have definite depth and equal distant are arranged on the paper, and the pencil which is produced by the roll of the paper is not sharpened by a sharpener. The utility model has convenient use, can save a lot of wooden material, reduces production cost, has economical benefits and has social benefits.

Description

A kind of pencil that rolls

The utility model relates to a kind of writing appliance, particularly relates to a kind of pencil of writing usefulness.

In the prior art, the pencil of writing usefulness has two big classes, and a kind of is Wood-bar pencil, this pen is complex process not only, the cost height, and need to consume a large amount of high-quality timber, need during use to cut, both wasted with cutter, inconvenient again, another kind of is the various propelling pencils that occur in recent years, though this propelling pencil is handsome in appearance, easy to use, but because complex structure, it is also high to manufacture cost, and fragile, lead for retractable pencil is meticulous in addition, very easily rolls over core during use.

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of cost low, manufactures easyly, cuts without cutter during use, can save the paper roll pencil of timber.

The utility model can reach by following measure, as shown in the figure, the utility model is made up of lead for retractable pencil and exoperidium, it is characterized in that exoperidium is a paper material, be shaped as trapezoidally, paper is divided into tow sides, and the two sides all is pressed with the twill of parallel equidistant, minor face place at trapezoidal paper also is pasted with plastic sheeting 1, scribbles binding agent on the film.

Trapezoidal paper can be isosceles trapezoid, also can be right-angled trapezium, the recto embossing than reverse side embossing with respect to the hypotenuse mistake of trapezoidal paper after 0.3～0.8mm, the embossing of positive and negative can not misplace yet, the spacing of twill is 0.3mm, the width that is bonded in the plastic sheeting on the paper is 30mm, when rolling, lead for retractable pencil is placed the Chang Bianchu of trapezoidal paper, after being rolled into column, by the further rolling-in of plastic sheeting, last, plastic sheeting just entirely sticks on the penholder.

Compared with prior art, the utlity model has and manufacture easyly, cost is low, and is easy to use, can save the advantage of a large amount of timber.
