Abstract
The utility model relates to a drawing tool, which can be used for classroom teaching. A female ruler and a male ruler rotate around a screw for 0 to 180 DEG. Angles with different degrees can be drawn by means of angle scale lines on a female shaft head. Circles with different radii can be drawn by means of scale marks of radii of circles on a male head. When the female ruler and the male ruler rotate around a screw for 0 to 180 DEG, straight lines with different lengths can be drawn by means of centimeter scale lines on the ruler body. The utility model fully has all functions of a straight ruler, a set square, and a pair of compasses, and overcomes a plurality of defects of the traditional teaching aids, with the advantages of simple structure and convenient operation. The materials and the manufacturing cost of the utility model is almost the same with the compasses in the traditional teaching aids.
Description
The utility model relates to a kind of drawing tool that is used to impart knowledge to students, i.e. multifunctional drawing instrument.
At present, known teaching drawing tool contains set square, compasses, ruler.Its weak point is that these drawing tool quantity are many, volume is big, cracky, not portable and keeping, and consumes a large amount of timber.
The purpose of this utility model provides a kind of drawing tool, and all functions of its comprehensive compatible ruler, set square, compasses are simple in structure, convenient and practical, be easy to carry and take care of, though be materials and cost all with tradition in compasses very nearly the same.Can thus be country and save a large amount of timber, have the good value of environmental protection.
The purpose of this utility model is achieved in that cloudy chi and positive chi is flexibly connected round screw, wherein blade cloudy chi one end that indicates the centimeter scale line is provided with the iron pin of band soft-body, the other end is provided with cloudy spindle nose, cloudy spindle nose is provided with flight and angle index line, the end that blade indicates the positive chi of centimeter scale line is provided with the chalk placed hole and moves back ledge for chalk on blackboard, the other end is provided with positive spindle nose, and positive spindle nose is provided with flight and radius of circle graduation mark.
Owing to adopt such scheme, can make people when the teaching mapping, without any need for aid, utilize this multifunctional drawing instrument just can draw round, straight line and angle, and be easy to carry about with one and take care of.
Below in conjunction with accompanying drawing and enforcement side the utility model is further specified.

In Fig. 1, cloudy chi (1) is done 0 °～180 ° rotations with positive chi (2) round the screw (6) of flight (5) lining, utilize angle index line (8) on the cloudy spindle nose (3) can make the angle of the different number of degrees, also can utilize radius of circle graduation mark (9) on the positive spindle nose (4) to make the circle of different radii.
In figure (2), when cloudy chi (1) and positive chi (2) when screw (6) rotates to 180 °, utilize centimeter scale line (7) on the blade can make the line segment of different length.
In figure (3), the center line of the center line of cloudy spindle nose (3) and cloudy chi (1) blade is orthogonal, and cloudy spindle nose (3) is provided with flight (5) and angle index line (8).
In figure (4), the center line of positive spindle nose (4) overlaps mutually with the center line of positive chi (2) blade, and flight (5) and radius of circle graduation mark (9) are set on the positive spindle nose (4).
In figure (5), an end of positive chi (2) is provided with chalk placed hole (10) and moves back ledge for chalk on blackboard (11).
In figure (6), an end of cloudy chi (1) is provided with an iron pin (12), is with soft-body (13) on the iron pin (12).
Claims (4)
