CN2255920Y - Multifunctional pen - Google Patents

Abstract

The utility model relates to a multifunctional pen, a pen holder and a pen core of the multifunctional pen are assembled and then can be combined into a cone body, a multi-prism cone body or one to two inclined planes at the part of a pen point. The utility model is characterized in that a cone body surface or an inclined plane in the part of the pen point can be kept on the same straight line or on the same plane with the pen point. The surfaces of pen points of various prime ball pens, movable lead core pens, etc. are rugged, and compared with the multifunctional pen, the surfaces are just opposite. When the multifunctional pen is used, the cone body surface or the inclined plane of the pen point is in line contact or in surface contact with the surfaces of tools, such as straight rules, squares, triangular plates, T-squares, etc. Therefore, when the multifunctional pen is used, observation is direct, writing and looking for points are easy, line scribing are steady and correct, the utility model not only can be used for writing and drawing, but also can be used for scribing lines and drawing, the utility model is a type that one pen with multi functions, and the occurence of the multifunctional pen can be widely obtained the acceptance of designers, woodworkers and students.

Description

Multipurpose pencil

The utility model relates to the improvement of the pen head part manufacturing shape of existing various pens.

The various pens of manufacturing both at home and abroad so far exist weak point at pen head part, and as existing various pencils, nib will be cut with cutter earlier during use, pen core frangibility and wearing and tearing; Waste is caused because of using in use to 1/3 or 1/4 o'clock; All to change a large amount of high-quality timber of country every year for making pencil.Existing for another example various ball pens, movable lead pen etc., their written surface are by combination of shapes such as various cylinders, cone, circular arc bodies and prejudice Fig. 1, Fig. 2, surface irregularity.This is unimportant for writing, but the designer draws, the carpenter rules, just makes troubles when the student maps.Draw, when line, mapping, at first written surface will rely on the chi limit face of instruments such as ruler, set square, angle square, T-square to rule, because written surface irregularity, observes not intuitively, starts to write and looks for a trouble; Secondly the nib surface is that the point that is moving contacts with chi limit face, and is not steady during use, the easy deflection of the lines of being drawn; Have again the pen concavo-convex omoplate and the chi corner as colliding, will draw deflection or interruption to lines.Therefore the function of use of existing various pens is placed restrictions on.

The purpose of this utility model is that a kind of multipurpose pencil will be provided, its written shape, and as Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8.The nib surface of this multipurpose pencil is straight retention wire to be contacted or the face contact with the chi limit face of scoring tool, and it can prevent deflection, the interruption of the bar of ruling effectively, thereby has improved the function of use of pen.

The purpose of this utility model is achieved in that the cone face (2) of nib (1) and different shape in pen head part or inclined-plane (3) are combined on the same straight line or on the same plane.Can manufacture cone according to the feature nib of multipurpose pencil nib shape and see that Fig. 3, Fig. 4, polygonal pyramid body see that Fig. 5, Fig. 6, oval cone are seen cone such as Fig. 7 or manufactured one to two inclined-plane at pen head part and see Fig. 8 (the written shape of Fig. 7 Fig. 8 is applicable to the carpenter).Above-described written shape can or add the shape that annex assembles by penholder and pen core, also can or add the shape that annex manufactures an integral body by penholder and pen core.The surface that it is straight is compared just in time opposite with existing various rough written surfaces.

The most advanced and sophisticated formed acute angle of penholder by this multipurpose pencil feature is made in order to increase the strength of materials, allows little angle to see 4 places in the enlarged drawing 9.Pen needs to tilt in use and the nib surface is that line or face contact with the chi limit face major part of scoring tool, and the stria that becomes because of little dihedral does not have influence for using.Pen core adopts pencil-lead or colored pen core, and for the convenience of the users and pen attractive in appearance, nib (1) shape can directly create, and also can have the user to take care of oneself and see Fig. 6.

This multipurpose pencil removes the shape on nib surface during fabrication, and by outside its character shape manufacturing, all the other all get final product by shape, the structure choice manufacturing of existing various pens.

The chi limit face of surface of this multipurpose pencil and scoring tool can retention wire or face contact during use.Therefore observe directly perceived; Start to write and look for a convenience; Line is steadily correct.It can prevent deflection, the interruption of the bar of ruling effectively; Reached the purpose that replaces high-quality timber with plastics, steel; It can write drawing, again can rule the mapping being the typical case who uses more.Its appearance will obtain designer both domestic and external, carpenter, student and accept.

Claims (3)

1, this multipurpose pencil is on the basis of shape, structure at existing various pens, only improves the surface configuration of nib, it is characterized in that the cone face of nib and different shape, and perhaps the inclined-plane is combined on the same straight line or on the same plane.

2, multipurpose pencil according to claim 1 is characterized in that nib is shaped as the cone face, inclined-plane, cone, polygonal pyramid body, cone such as oval cone or manufacture one to two inclined-plane at pen head part.

3, according to claim 1,2 described multipurpose pencils, it is characterized by written shape, it is by penholder and pen core or add the shape that annex assembles, and also can or add the shape that annex is made an integral body by penholder and pen core.
