Abstract
The invention relates to a multifunctional teaching ruler which belongs to teaching aids and comprises a set square and a protractor, wherein the set square comprises an isosceles right-angle set square and a 30-DEG-angle and 60-DEG-angle set square; a handle is arranged on a straight side of the 30-DEG-angle and 60-DEG-angle set square; one angles of the two set squares are connected through a rotating shaft; and the central point of the protractor is connected with the two set squares through a rotating shaft. The multifunctional teaching ruler is capable of reducing the cumbersome matter that a teacher needs to carry various teaching aids when in class and increasing the teaching efficiency, can serve as the set square, the protractor and the straight ruler when in use, has no need of rotating the various teaching aids and is very convenient.
Description
Technical field
The present invention relates to the teaching aid that a kind of teacher uses on class to classmates, specifically a kind of Multifunctional teaching aid chi.
Background technology
Math teacher often can use ruler, set square and protractor to draw at blackboard in that when several explain for classmates, and various rulers are used alternatingly, and trouble is lost time when not only using, and carries also inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of Multifunctional teaching aid chi, this Multifunctional teaching aid chi integrates set square, protractor and ruler, uses when making things convenient for math teacher at school.
The present invention solves the technical scheme that its technical problem takes: a kind of Multifunctional teaching aid chi, comprise set square and protractor, it is characterized in that, described set square comprises that an isosceles right angle triangle and 1 is spent, 60 degree angle set squares, 30 degree, straight flange of 60 degree angle set squares are provided with handle, one jiao of two set squares is passed through rotating shaft connection, and the central point of protractor is connected with two set squares by rotating shaft.
The invention has the beneficial effects as follows: this Multifunctional teaching aid chi reduces teacher need to carry the loaded down with trivial details of multiple teaching aid on class, can use as set square, protractor and ruler during use, need not to switch back and forth instrument, very convenient, improves efficiency of teaching.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 130 degree, 60 degree angle set squares, 2 right angle triangles, 3 protractors, 4 handles, 5 rotating shafts.
The specific embodiment
As shown in Figure 1.A kind of Multifunctional teaching aid chi, comprise set square and protractor 3, described set square comprises that an isosceles right angle triangle 2 and 1 is spent, 60 degree angle set squares 1,30 degree, 1 one straight flanges of 60 degree angle set squares are provided with handle 4, one jiao of two set squares by a rotating shaft 5 connections, the central point of protractor 3 is connected with two set squares by rotating shaft 5, and two set squares and protractor 3 be around the shaft 5 rotations all.
This Multifunctional teaching aid chi can draw by two set squares 30 degree, 45 degree, 60 degree and an angle of 90 degrees of standard, again can two set squares pendulum is neat, use as ruler, and the protractor 3 between two set squares makes things convenient for teacher to take measurement of an angle.
