Embodiment
As shown in Figs 1-4, a kind of multifunctional mathmatical mapping compasses, including handle 1, compass foot 2, mapping ruler 5 and collet
7, the bottom of the handle 1 is equipped with compass foot 2, and the compass foot 2 includes left compass foot 21 and right compass foot 22, the left circle
The inside of regulation foot 21 is equipped with slot 3, and by mapping, the dimension of picture that ruler 5 directly draws to compasses accurately measures, no
Other survey tools of need tyre, to be effectively increased the use function of mathematic(al) construction compasses, and in the use work(for increasing compasses
Do not increase the volume of compasses when energy, is convenient for the carrying of mathematic(al) construction compasses, the bottom of the left compass foot 21 that mapping is installed directly
One end of ruler 5, the mapping ruler 5 is rotatablely connected by fixing axle 4 and left compass foot 21, on the side of the right compass foot 22
