Abstract

Disclosed is a triangular writing and metering pen. The cross section of each of a penholder and a pen cap of the pen is triangular, and both the penholder and the pen cap are provided with three planes. The triangular writing and metering pen is characterized in that graduations of measurement units are marked on the penholder and the pen cap, the measurement units including centimeter and inch are marked on the three planes of each of the triangular penholder and the triangular pen cap, and computational formulas, laws, public service advertisements, adages of encouragement and patterns are printed on the same. The triangular writing and metering pen can be used as a ruler or a proportional scale for conversion between centimeter and inch.

Description

Triangle is write the metering pen

Technical field:

The utility model relates to that a kind of not only can be used for writing but also can be used as the penholder external form that ruler uses be leg-of-mutton pen.

Background technology:

At present, known kind and external form pattern are a lot, are the gel ink pens of change-fountain pen core but use maximum, its structure generally by penholder, connect screw, the cap for brush, pen clip, top cap, hold cover, the tail plug is formed.Mostly penholder, the cap for brush are round, and the place of holding a pen is little with the thumb, forefinger, the middle finger contact-making surface that hold a pen, and it is big that finger is produced pressure, writes easy fatigue for a long time, do not have to be used as the function that ruler uses.

Summary of the invention:

The pressure that produces when holding a pen in order to alleviate; Make write lighter, happy; Can increase the ruler purposes of pen again, the utility model provides a kind of triangle to write the metering pen, and this not only has the writing function of general pen; Also have ruler and centimetre with the inch the conversion scale function, can work as ruler and engineer's scale the use.

The technical scheme that the utility model technical solution problem is adopted is: a kind of triangle is write the metering pen; Penholder, the cap for brush cross section of this pen are triangle; Make the surface of the penholder and the cap for brush have three planes, it is characterized in that: mark measurement unit scale on penholder, the cap for brush.

Because this penholder is a triangle; To contact the position of triangle penholder respectively just in time be three planes of penholder for thumb, forefinger, middle finger when holding; With respect to holding the round bar pen, increased the contact area of finger with pen, reduced to point the pressure of penholder to pointing when holding a pen; Write lighter, indefatigability.Can also help correctly to grasp pen holding posture and correct pen holding posture for the pupil.

The beneficial effect of the utility model is: can reduce when 1, writing penholder to the finger pressure, make write lighter, indefatigability; 2, help correctly to grasp pen holding posture; 3, have the ruler function and centimetre and inch conversion scale function, can work as the use of ruler and engineer's scale; 4, save material than round bar pen; 5, owing to have ruler and engineer's scale function, therefore can reduce and be with ruler to take up space in the writing case in addition; 6, the triangle ruler is more durable than plane ruler; 7, three of penholder planes also can make full use of and print computing formula, law, public welfare advertisement, the maxim of pursuing a goal with determination, pattern; 8, anti-skid.

Description of drawings:

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is that the utility model triangle is write a metering side left view.

Fig. 2 is that the utility model triangle is write a metering front front view.

Fig. 3 is that the utility model triangle is write a metering rear elevation view.

Fig. 4 is that the utility model triangle is write a metering front plan view.

Fig. 5 is that the utility model triangle is write a metering cap for brush 3 dimensional drawing.

Fig. 6 is that the utility model triangle is write a metering penholder 3 dimensional drawing.

Fig. 7 the utility model triangle is write a metering 3 dimensional drawing.

Fig. 1 explanation: Fig. 1 writes a metering side left view for the utility model triangle; Penholder, the cap for brush are triangle; Penholder, the cap for brush have three planes, and the cap for brush is combined into one-pen on the Pen-holder sleeve, and this pen has three planes; The side left view has reflected one of them plane, three planes of this pen, and the afterbody from pen on this plane begins to the cap for brush mark unit scale of measuring length is arranged.

Fig. 2 explanation: Fig. 2 writes a metering front front view for the utility model triangle; Penholder, the cap for brush are triangle; Penholder, the cap for brush have three planes, and the cap for brush is combined into one-pen on the Pen-holder sleeve, and this pen has three planes; The front front view has reflected two planes wherein, three planes of this pen, and the afterbody from pen on these two planes begins to mark the unit scale of measuring length respectively to the cap for brush.

Fig. 3 writes a metering rear elevation view for the utility model triangle; Penholder, the cap for brush are triangle, and penholder, the cap for brush have three planes, and the cap for brush is combined into one-pen on the Pen-holder sleeve; This pen has three planes; Rear elevation view has reflected one of them plane, three planes of this pen, the unit scale inch that on this plane, begins to mark tolerance length respectively to the cap for brush from the afterbody of pen with centimetre, and represented inch with centimetre conversion scale.

Fig. 4 is that the utility model triangle is write a metering vertical view, has illustrated the utility model triangle to write the triangular shaped of metering pen.

Fig. 5 is that the utility model triangle is write a metering cap for brush 3 dimensional drawing, is cap for brush external form sketch map, because Show Color is darker, the length linear module that marks on the cap for brush does not display.

Fig. 6 is that the utility model triangle is write a metering penholder 3 dimensional drawing, is penholder external form sketch map, because Show Color is darker, the length linear module that marks on the penholder does not display.

Fig. 7 the utility model triangle is write a metering 3 dimensional drawing, is the external form sketch map of pen, because Show Color is darker, the length linear module of mark does not display on the pen.

The specific embodiment:

In Fig. 6, pack pen core in the penholder into, Fig. 5 cap for brush is enclosed within on Fig. 6 penholder.Begin to the cap for brush from the penholder afterbody, on three faces of triangle pen, mark a centimeters long measure scale and an inch unit scale respectively, like Fig. 1, Fig. 2, shown in Figure 3.Penholder, the cap for brush constitute long triangle ruler, and three faces of this ruler can use, and wherein one side can also be worked as the foot use.Penholder, the cap for brush also can be respectively when the ruler uses.The utility model triangle is write the metering pen and can be increased and the contact area that holds a pen and point than the round bar pen, reduces to point the pressure that holds a pen that bears.Suppose that circle penholder and triangle penholder are that sheet material of the same race is processed; The round bar pen of the same outside dimension of triangle penholder is in light weight; Penholder saves material 23.57%, and for example: the diameter of supposing the round bar pen is 10mm, and then the garden girth is 3.14mm; The girth that connects equilateral triangle in the external diameter of this round bar pen is 2.4mm, therefore (3.14-2.4)/3.14=0.2357).

Claims

1. a triangle is write the metering pen, and penholder, the cap for brush cross section of this pen are triangle, make the surface of the penholder and the cap for brush have three planes, it is characterized in that: mark measurement unit scale on penholder, the cap for brush.
