Description
Technical field
The utility model relates to a kind of mathematical education compasses, belongs to realia technical field.
Background technology
In mathematical education is drawn, because compasses can only be used for picture circle, and not there is Measurement scales, take measurement of an angle, draw leg-of-mutton effect, when therefore teacher draws, need to hold a whole set of drawing instrument, extremely inconvenient.
Summary of the invention
The utility model one of has problems to solve in above-mentioned prior art, provides the mathematical education compasses that a kind of structure is simple, easy to use, serve many purposes.
The utility model solves the technical scheme that its technical problem adopts:
A kind of mathematical education compasses, comprise drawing leg and location leg, it is hinged that hinge is passed through in the end of described drawing leg and the end of location leg, the free end of described drawing leg is provided with the pen cap, described drawing leg and location leg opposite side are provided with continuous print scale, described location leg is provided with groove, rule is provided with in described groove, described rule lower end and location leg hinge, described drawing leg is provided with angle graduated scale with the hinged end of location leg, described angle graduated scale is by described hinge and described drawing leg and locate leg and be hinged together, the central point of described angle graduated scale is overlapping with described hinge.
The utility model also has following additional technical feature:
Preferably, described drawing leg and location leg opposite side are linear structure.
Preferably, the outside of described drawing leg and location leg is provided with continuous print scale.
Beneficial effect: mathematical education compasses of the present utility model can not only be used for picture circle, Measurement scales can also be used for, draw triangle, and can the angle of diabolo measure, draw the triangle of required angle, the triangle with fixed length limit can also be drawn, easy to use, can one-object-many-purposes be realized.
Additional aspect of the present utility model and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present utility model.
