Abstract
The utility model discloses a multifunctional teaching ruler, which belongs to a teaching tool. The teaching ruler comprises a set square and a protractor, wherein the set square comprises an isosceles right triangular set square and a set square of 30 degrees and 60 degrees; one straight edge of the set square of 30 degrees and 60 degrees is provided with a handle; one corners of the two set squares are connected through a revolving shaft; and the center point of the protractor is connected with the two set squares through revolving shafts. Due to the adoption of the multifunctional teaching ruler, the problem that a teacher needs to carry a plurality of teaching tools in class is solved; and the teaching ruler can be taken as a set square, a protractor as well as a straight ruler without changing tools, and is very convenient, and the teaching efficiency is increased.
Description
Technical field
The utility model relates to the teaching aid that a kind of teacher uses for classmates on class, specifically a kind of multi-functional teaching aid chi.
Background technology
Math teacher uses ruler, set square and protractor to draw at blackboard in that when several explain for classmates through regular meeting, and various rulers are used alternatingly, and trouble is lost time when not only using, and carries also inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of multi-functional teaching aid chi, and this multi-functional teaching aid chi integrates set square, protractor and ruler, uses when making things convenient for math teacher at school.
The technical scheme in the invention for solving the technical problem is: a kind of multi-functional 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 beneficial effects of the utility model are: this multi-functional teaching aid chi reduces teacher need 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 utility model.
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 multi-functional 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 5 rotations around the shaft all.
This multi-functional teaching aid chi can be by two set squares draw 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.
