Description
Technical field
The utility model relates to a kind of rulers, and in particular to a kind of mathematical education Novel ruler belongs to teaching aid field.
Background technique
During mathematical education, teacher imparts knowledge to students commonly using teaching aids such as ruler, set squares, and currently on the market
The ruler and set square of offer are single teaching aids, and when use need to carry respectively, and existing ruler is mostly regular length, to using
It makes troubles with carrying.
Summary of the invention
The utility model is to solve the ruler that provides currently on the market and set square is single teaching aid, and when use needs to distinguish
It carries, and existing ruler is mostly regular length, to using and the problem of carrying is made troubles, and then proposes that a kind of mathematical education is used
Novel ruler.
The utility model adopts the technical scheme that in order to solve the above problem: the utility model include ruler body, sliding slot,
It two strip bulges, shrinkage-rule, two slideways, the first fastening bolt, the first spinner handle, the second fastening bolt, the second spinner handle and stretches
Contracting bar, the cross section of ruler body are inverted L shape, and ruler body top is provided along its length sliding slot, sliding slot two sidewalls difference
Equipped with a strip bulge, two strip bulges are oppositely arranged, shrinkage-rule two sidewalls be respectively equipped with along its length one with
The compatible slideway of strip bulge, two slideways are oppositely arranged, and shrinkage-rule is connected by two slideways and two strip bulge slide fits
It connecing, one end of the first spinner handle is flexibly connected by the first fastening bolt with ruler body front end lower-left antetheca, and the one of the second spinner handle
End is flexibly connected by the second fastening bolt with ruler body front end bottom right antetheca, and the second spinner handle front end is equipped with telescopic rod.
The beneficial effects of the utility model are: the utility model design is simple, practical and is easy to carry about with one, set by telescopic
Meter, can effectively realize the ruler use demand of different length, meanwhile, bispin bar screws out the function that set square can be realized, and passes through
The use of flexible spinner handle, can effectively realize the demand of different angle triangle.
