Between the second ruler is connected with by movable axis, be movably installed with chalk mounting seat on second ruler.
Further, described piece coordinates with sliding bar.
Further, it is respectively equipped with angle index line on first dial and the second dial.
Further, it has been respectively fixedly connected with arrow on first ruler and the second ruler termination, described first
Length scale line is respectively equipped with ruler and the second ruler.
Further, chalk mounting hole, the chalk mounting seat top are provided with above the outer side elevation of the chalk mounting seat
By being threaded with Top fastening screw, the outer side elevation lower section of the chalk mounting seat is by being threaded with Top fastening screw, the chalk
Mounting seat is slidably matched with the second ruler.
The utility model has an advantageous effect in that compared with prior art：A kind of mathematical education blackboard, using new
Structure, when math teacher needs picture geometric figure, operate the first ruler and the second ruler precisely can quickly draw straight line,
Not only straight line length is accurate for polygon, circular arc and circle, straight line and polygon, and angle is also accurate, and the radius of circular arc and circle is big
It is small also accurately to draw, it is simple to operate, substantially increase the quality of instruction of math teacher, the letter of the utility model structure
Single, easy to use and reliable, using effect is good, practical.
