Abstract

The utility model discloses a multipurpose ruler for mathematics, comprising a drawing square (1) and a protractor (5), wherein a chute (2) is arranged on the bevel edge of the drawing square (1); the zero-point part of a collapsible ruler (3) with scales is connected to the zero-point part of the protractor (5) via a bolt (4), and the bolt (4) is arranged in the chute (2) of the drawing square (1); and a fixing device (7) for fixing the collapsible ruler (3) is arranged on any one right-angled edge of the drawing square (1). By using the structure above, the effects of saving time and labour, and providing multiple purposes for one teaching aid are realized.

Description

The mathematics multipurpose ruler
Technical field
The utility model relates to a kind of mathematics teaching aid, relates in particular to a kind of mathematics multipurpose ruler.
Background technology
At present, in the mathematical education process, use teaching aid mappings such as ruler, protractor, compasses commonplace, but all more single in use, when teaching, use inconvenience, not only increase teacher's labour intensity, and wasted valuable instructional blocks of time.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, and is time saving and energy saving, the multi-purpose mathematics multipurpose ruler of a kind of teaching aid.
The technical scheme of the utility model is a kind of mathematics multipurpose ruler; It comprises drawing square 1 and protractor 5; It is characterized in that: on the hypotenuse of said drawing square 1, be provided with chute 2; The zero point place of the Expansion ruler 3 of one band scale is connected the place at zero point of said protractor 5 through bolt 4, and said bolt 4 is arranged in the chute 2 of said drawing square 1, on said drawing square 1 arbitrary right-angle side, is provided with the fixture of fixing said Expansion ruler 3.
The technical scheme of the utility model also has on said Expansion ruler 3 and is provided with chalk clamper 6 away from an end of bolt 4.
The beneficial effect of the utility model is through on the hypotenuse of said drawing square 1, being provided with chute 2; The zero point place of the Expansion ruler 3 of one band scale is connected the place at zero point of said protractor 5 through bolt 4, and said bolt 4 is arranged in the chute 2 of said drawing square 1, on said drawing square 1 arbitrary right-angle side, is provided with the fixture 7 of fixing said Expansion ruler 3; During use; Through cooperating and slip in the chute 2 on drawing square 1 hypotenuse simultaneously of Expansion ruler 3 and protractor 5, can make the circular arc or the circle of straight line and any radius size at any angle easily, the fixture 7 that is provided with through drawing square 1 arbitrary right-angle side; Expansion ruler 3 is fixing; Can the handle of Expansion ruler 3 double as drawing squares 1 be used, it is time saving and energy saving to have realized, the multi-purpose effect of a kind of teaching aid.
