Abstract
The utility model relates to a multi-function instrument for drafting for satisfying the use of students. The utility model is composed of a protractor which is composed of a crossfoot having a center groove, and a linear foot having the center groove, and an indicating needle which is provided with an abscissa sliding rule, an ordinate sliding rule, the center groove and a sliding blade. Thus only one of the utility model can complete the drawing of an angle, a bisector of an angle, a sector, a circle, parallel lines, a rectangle and a square, and the tracing points of a function can also be conducted. The utility model has the advantages of easy portability and convenient operation.
Description
The utility model is the instrument with multiple drawing function that a kind of student uses.
At present, the student draws the fan-shaped of known central angle and radius, and draws known angle, bisector of angle, and circle, parallel lines, square and rectangle are carried out function described point etc., cooperate with instruments such as protractor, ruler and compasses just can finish.The instrument of student's needs is more, not portable like this, is difficult for keeping, in case lose an instrument, just can not finish some drawing well.
The purpose of this utility model is to have multiduty a kind of plotter for the student provides: it can not only draw angle, bisector of angle, fan-shaped, round, can also draw parallel lines, square and rectangle are carried out the function described point, and draw these figures and only need one in this instrument, just can finish rapidly.
The utility model is achieved in that protractor and the ruler 90 ° organically links together, just extended in one side of 90 ° of protractors, another side and this lengthening central channel on one side at protractor are equipped with vertical mark slip chi and slogan banner slip chi respectively, are equipped with pointer at the place, summit, right angle of 90 ° of protractors.
Because it is adopted technique scheme, this multi-function drawing instrument can satisfy some drawing requirements of student, and easy and simple to handle, easy to carry.
Below in conjunction with embodiment and accompanying drawing the utility model is made and to further specify.
In the drawings: (1) protractor; (2) crossfoot of central channel is arranged; (3) linear foot of central channel is arranged; (4) pointer of central channel is arranged; (5) slide plate; (6) slogan banner slip chi; (7) vertical mark slip chi; (8) flexible pin.
By protractor (1), the crossfoot (2) of central channel is arranged and have linear foot (3) organic connections of central channel to form the trunk portion of this multi-function drawing instrument, the crossfoot of central channel (2) is arranged and has linear foot (3) intersection of central channel to be equipped with have slide plate (5) and have central channel pointer (4), and can rotate.Slogan banner slip chi (6) and vertical mark slip chi (7) are equipped with the crossfoot (2) of central channel respectively and have on the linear foot (3) of central channel, and can slide.Be positioned on the crossfoot (2) of central channel and the intersection of the linear foot (3) of central channel is arranged at flexible pin (8), when firmly when stretching pin, needle point stretches out, and is late for, and needle point is withdrawn automatically.
Claims (2)
1, multi-function drawing instrument, be by the crossfoot that central channel is arranged (2), the linear foot (3) that central channel is arranged, protractor (1), slogan banner slip chi (6), vertical mark slip chi (7) is formed, and it is characterized in that slogan banner slip chi (6) is positioned on the crossfoot (2) of central channel, and vertical mark slip chi (7) is positioned on the linear foot (3) of central channel.
2, multi-function drawing instrument according to claim 1 is characterized in that the crossfoot of central channel (2) being arranged and having linear foot (3) intersection of central channel to be equipped with the pointer (4) of being with slide plate (5) and central channel being arranged.
