Abstract
The utility model provides an elliptic pencil-lead. The main body of the elliptic pencil-lead is an ellipsoid (1), the cross-section of which is an ellipse; and the size of the ellipsoid (1) can be customized according to requirements. Thin lines can be written by alternately using two long-axis ends (2), therefore, the elliptic pencil-lead is applicable to writing fine characters or drawing profiles in charcoal drawings. Thick lines can be written by alternately using two short-axis ends (3), therefore, the elliptic pencil-lead is applicable to writing bold-face characters or daubing in charcoal drawings. The pencil-lead can be made into various colors. The elliptic pencil-lead which is not easy to break off, does not need to be cut and can write the light-face characters and the bold-face characters is provided, and solves the technical problems respectively existing that in the prior art. the pencil-lead needs to be cut, is easy to break off due to fine pencil-lead and has single writing function.
Description
Technical field
The utility model belongs to the articles for writing technical field, the oval pencil core that is specifically related to a kind of not frangibility and exempts to cut.
Background technology
Popular pencil roughly is divided into traditional wooden pencil and propelling pencil at present, and wooden pencil is because of will often cutting penholder and pen core, and is consuming time bothersome, and waste material is extremely inconvenient; And non-sharpenning penholder of propelling pencil and pen core, though convenient, tiny careless slightly will the fractureing of its pen core, not only wasting pen core also influences the mood of writing with the author; These two kinds of pencil writing functions are single.
The utility model content
Utility model purpose of the present utility model is that a kind of not frangibility, exempt to cut and oval pencil core that thick light face can both be write will be provided, and will cut pen core and the pen core that have solved that prior art exists separately fracture and technical problem that writing function is single easily because of tiny.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of oval pencil core, and its main body is an ellipsoid, and its cross section is oval, and ellipsoidal thickness can customize as required.Be used alternatingly two director's axle heads and can write out thin lines, be applicable to and write light face or collude profile in the sketch.Be used alternatingly two place's minor axis ends and then can write out thicker lines, be applicable to and write smearing in boldface letter or the sketch.Pen core can be made into shades of colour.
Adopted a kind of oval pencil core of the utility model of above technical scheme to have following advantage: 1. because of being that main body is an ellipsoid, pen core is greatly improved on intensity, not frangibility; 2. be used alternatingly minor axis end or longitudinal end and can write thick or thin two kinds of lines and non-sharpenning pen core, and function is many with having improved the situation of pen core function singleness in the past.
