Description
Technical field
The utility model relates to mathematical education apparatus field, is specially a kind of Multifunctional math teaching aid.
Background technology
In mathematical education process, particularly geometry, geometric construction is a very important technical ability requirement in mathematical education,So need to often use drawing tools, existing math teaching aid mainly contains set square, ruler, protractor and compasses,But be the instrument of independent use, use and carry equal inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional math teaching aid, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of Multifunctional math teaching aid, comprise set square,Protractor, compasses the first bull stick, compasses the second bull stick, compasses the first fixed pole and compasses the second fixed pole, the back of the body of described set squareThree drift angle places of face are all fixed with sucker, and the positive middle-end of described set square is fixed with handle, described set square positiveDrift angle place is provided with rotating shaft, is fixed with compasses the first fixed pole, described compasses the first fixed pole on a positive side of described set squareOne end be connected with rotating shaft, the other end of compasses the first fixed pole is hinged with compasses the second fixed pole, another of described compasses the second fixed poleEnd be fixed with compasses sucker, on another positive side of described set square by the circle that has been fixed of clamping screw and locating holeAdvise the first bull stick, one end of described compasses the first bull stick is connected with rotating shaft, and the other end of compasses the first bull stick is provided with chalk slot,The positive bottom of described set square is fixed with protractor, and the round dot place of protractor is provided with through hole.
Preferably, described protractor is provided with semi-circular recesses.
Preferably, described locating hole does not run through set square.
Preferably, in described compasses the first bull stick and compasses the first fixed pole, be equipped with groove, and the width of groove is greater than respectively compassesThe width of the second bull stick and compasses the second fixed pole.
Compared with prior art, the beneficial effects of the utility model are: this Multifunctional math teaching aid, the back side by set squareSucker, can make teacher in when mapping without pinning set square with hand, easy to use, simultaneously by the positive compasses of set squareAssist mapping with protractor, make its function not only with set square, and there is the function of compasses and protractor, easy to use,Practical, the semi-circular recesses on throughput hornwork can make to measure more convenient, can be by compasses second in the time not using compassesBull stick and compasses the second fixed pole are taken in groove, not only easy to use, and have alleviated the weight of this teaching aid, practical.
