Abstract
The invention discloses a multifunctional drawing device which relates to teaching aids and has the functions of a ruler, a set square, a protractor and a bow compass, with convenient use. The multifunctional drawing device mainly consists of two rod pieces; the first rod piece is in ruler shape and the longitudinal direction of the first rod piece is provided with a long slot; a lead core clamp which can slide along the long slot is arranged in the long slot; one end of the second rod piece is the protractor and the other parts are in the ruler shape; the center of an arc at one end of the first rod piece is hinged with the circle center of the protractor on the second rod piece by a hollow shaft. The invention has simple structure, is convenient and practical and can be broadly applied to teaching activities.
Description
Affiliated technical field
The present invention relates to teaching aid, is a kind of multifunctional plotter specifically.
Background technology
These four kinds of simple function drawing instruments of existing set square, ruler, protractor and compasses are teaching aids that the student goes up the class hour indispensability.But, carrying and deposit this four kinds of teaching aids simultaneously, the student is very inconvenient.
Summary of the invention
For overcoming the deficiency that prior art exists, the invention provides a kind of multifunctional plotter, it has the function of set square, ruler, protractor and compasses simultaneously, and is very easy to use.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes two rod members, all indicate scale on two rod members.First rod member is a ruler shape, and it vertically has elongated slot, and being equipped with in elongated slot can be along the lead diameter clip of elongated slot slip.Second rod member, one end is a protractor, and other parts are ruler shape.The center of circle of protractor is hinged by hollow shaft on first rod member, the one end center of arc and second rod member.
Good effect of the present invention is: owing to adopt technique scheme, multifunctional plotter integrates ruler, set square, protractor and four kinds of functions of compasses, carries, uses and deposit all very convenient.
Description of drawings
Accompanying drawing is the structural representation of multifunctional plotter.
Among the figure, 1, first rod member, 2, second rod member, 3, protractor, 4, hollow shaft, 5, elongated slot, 6, lead diameter clip.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
In the drawings, first rod member 1 and second rod member 2 all indicate the length scale, and first rod member 1 is a ruler shape, and it vertically has elongated slot 5, and being equipped with in elongated slot 5 can be along the lead diameter clip 6 of elongated slot slip.Second rod member, 2 one ends are protractors 3, and other parts are ruler shape.The center of circle of protractor 3 is hinged by hollow shaft 4 on first rod member, the 1 one end center of arc and second rod member 2.
