Abstract
A kind of multifunctional teaching tools, it is characterised in that：45 degree of rulers are set as isosceles right triangle；45 degree of rulers are provided with protractor, and protractor is set as engraved structure；Attached ruler is set as 15 degree, 30 degree and 135 degree of triangle；45 degree of rulers and attached ruler match.It is more single that the present invention solves existing set square function, accounts for the big problem of memory space.It when using multifunctional teaching tools, uses as 30 degree, 60 degree and 90 degree of set square, when needing to draw more angles, 45 degree of rulers and attached ruler is separated under normal conditions, to be combined into more angles, then be equipped with protractor use.The present invention is made of 45 degree of rulers, attached ruler and protractor, and the present invention is easy to use, can satisfy different demands, structure is simple, and manufacturing cost is low, easy to spread.
Description
Technical field
The present invention relates to realia class, especially a kind of multifunctional teaching tools field.
Background technique
Currently, existing set square is all two, respective function is more single, while accounting for that memory space is big, this is for making
It is pretty troublesome for user.
Summary of the invention
The present invention is one kind more single in order to solve existing set square function, accounting for the big problem of memory space, and provide
Multifunctional teaching tools.
Technical solution：
The present invention is made of 45 degree of rulers, attached ruler and protractor.45 degree of rulers are set as isosceles right triangle；45
Degree ruler is provided with protractor, and protractor is set as engraved structure；Attached ruler is set as 15 degree, 30 degree and 135 degree of triangle；40
Five degree of rulers and attached ruler match.
Beneficial effect：
It is more single that the present invention solves existing set square function, accounts for the big problem of memory space.When use multifunctional teaching tools
When, it is used under normal conditions as 30 degree, 60 degree and 90 degree of set square, when needing to draw more angles, by four
15 degree of rulers and the separation of attached ruler to be combined into more angles, then are equipped with protractor use.Bring a set square function
Multiplicity accounts for the small benefit of memory space.The present invention is easy to use, can satisfy different demands, structure is simple, manufacturing cost
It is low, it is easy to spread.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is overall structure diagram of the invention.
Wherein, 1. 45 degree of rulers, 2. attached rulers, 3. protractors.
Specific embodiment
As shown in Figure 1, the present invention is made of 45 degree of rulers, attached ruler and protractor.It is straight that 45 degree of rulers are set as isosceles
Angle triangle；45 degree of rulers are provided with protractor, and protractor is set as engraved structure；Attached ruler is set as 15 degree, 30 degree and 135
The triangle of degree；45 degree of rulers and attached ruler match.
When using multifunctional teaching tools, used under normal conditions as 30 degree, 60 degree and 90 degree of set square,
When needing to draw more angles, 45 degree of rulers and attached ruler are separated, to be combined into more angles, then are equipped with angulation
Device uses.
