Description

The mathematics plotter
Technical field
The utility model relates to a kind of mathematics plotter.
Background technology
At present, the mathematics usefulness relate to of drawing has: ruler, set square, compasses, protractor etc.Teacher and student need to prepare a plurality of instruments when drawing, and use numerous and diversely, carry inconvenience.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of mathematics plotter, and it can replace ruler, set square, compasses and protractor to use, and has multi-functional characteristics.
The technical scheme in the invention for solving the technical problem is: the left end of main scale and angulation dish are fixed, the top extended line of main scale is crossed the center of circle of angulation dish, the right-hand member of main scale is the compasses pin fixedly, the left end of secondary chi and the center of circle of angulation dish are hinged, the following extended line of secondary chi is crossed the center of circle of angulation dish, the right-hand member of secondary chi is the bow pen holder fixedly, on described main scale, secondary chi and the angulation dish graduation mark is arranged all.
The utility model can replace ruler, set square, compasses and protractor to use, and has multi-functional characteristics.Portably use conveniently.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the secondary chi deployed condition of a utility model Fig. 1 schematic diagram.
The specific embodiment
As shown in drawings, the left end of main scale 3 and angulation dish 1 are fixing, and the top extended line of main scale 3 is crossed the center of circle of angulation dish 1, and the right-hand member of main scale 3 is compasses pin 5 fixedly.The left end of secondary chi 2 and the center of circle of angulation dish 1 are hinged, and the following extended line of secondary chi 2 is crossed the center of circle of angulation dish 1, and the right-hand member of secondary chi 2 is bow pen holder 4 fixedly.On described main scale 3, secondary chi 2 and the angulation dish 1 graduation mark is arranged all.Secondary chi 2 with main scale 3 with can make short ruler and use together, is opened secondary chi 2 and main scale is spent for 3 one-tenths 180, can be done long ruler use.
