Abstract
The utility model relates to a teaching instrument, in particular to a multi-functional rotary plotter which can perform teaching at the class blackboard. The utility model comprises a Z ruler, an X ruler and a Y ruler, wherein the Z ruler and one end of the X ruler are rotate connected by a rivet, the X ruler and the middle end of the Y ruler are rotate connected with a tip end screw, and the Z ruler body is also equipped with a calipers rotary hole position. The utility model can be distorted to common used two kinds of triangles, also can be distorted to triangles with multiple kinds of angles, can draw a square, a rectangle, a parallelogram and each kind of pictures, also can be used as the calipers to draw a round, the ruler can be folded at common time, which is convenient for placing and carrying.
Description
Technical field
The utility model relates to teaching aid, and referring in particular to the multifunctional rotary of imparting knowledge to students on the blackboard of classroom changes plotting apparatus.
Background technology
Classroom instruction at present generally is with bigger set square with chi, setting-out on blackboard, be various angles and the line segment of drawing easily, must be used with two set squares, the one, equilateral right-angle triangle, one is 60 ° and 30 ° of right-angle triangles, also needs compasses in order to draw circle, the teacher needs on class to embrace and goes up a lot of teaching aids and enter the classroom, and is very inconvenient.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provides a kind of simple in structure, flexible and changeable, and the multifunctional rotary that a chi is used more changes plotting apparatus.
The technical solution of the utility model is: the utility model comprises Z chi, X chi, Y chi, wherein the Z chi is connected both with rivet is rotatable with X chi one end, the X chi is connected both with pointed screw is rotatable with Y chi middle-end, Z chi blade is provided with the magnetic snap-fastener, Y chi and X blade are provided with the magnetic snap-fastener, and X chi blade also is provided with compasses rotating hole position.
The utility model can be deformed into two kinds of set squares commonly used, can also be out of shape the triangle that becomes multiple angles, can draw square, rectangle, parallelogram, various patterns can also be made compasses and use the circle of drawing, usually chi can be folded up, be convenient to place and carry.
