Abstract
The utility model discloses a mathematical multi-purpose ruler, which comprises a transparent base ruler (1) with scales, wherein the left end part of the base ruler (1) is vertically and fixedly connected with the upper end part of a transparent secondary ruler (2) with scales; the middle part of the base ruler (1) is reversely coated with a protractor (3); and angle lines of the protractor (3) form channels (6) on the surfaces of the base ruler (1) and the secondary ruler (2). By using the structure, time and labor are saved, and the effect that one teaching aid has multiple purposes is realized.
Description
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 the transparent basic chi 1 of band scale; It is characterized in that: vertical being fixedly connected with transparent secondary chi 2 upper ends of a band scale in the left part of said basic chi 1; The middle part of said basic chi 1 oppositely is coated with protractor 3, and the angle line of said protractor 3 forms groove 6 on the surface of said basic chi 1 and secondary chi 2.
The technical scheme of the utility model is respectively equipped with bar magnet 4 in the inside, two ends of said basic chi 1.
The technical scheme of the utility model is respectively equipped with sucker 5 at the right-hand member of said basic chi 1 and the lower end of said secondary chi 2.
The beneficial effect of the utility model is vertical being fixedly connected with transparent secondary chi 2 upper ends of a band scale in the left part of said basic chi 1; The middle part of said basic chi 1 oppositely is coated with protractor 3; The angle line of said protractor 3 forms groove 6 on the surface of said basic chi 1 and secondary chi 2, can basic chi 1, secondary chi 2 and protractor 3 be used in combination, during teaching; Can make the circular arc or the circle of straight line and any radius size at any angle easily; And use bar magnet 5 and sucker 6 to be fixed on the blackboard as aid, it is time saving and energy saving to have realized, the multi-purpose effect of a kind of teaching aid.
