Abstract
The utility model relates to a measurement tool, in particular to a multifunctional protractor, which integrates a protractor, a ruler, a geometric template and a compass. The multifunctional protractor is a semicircular protractor with the graduated scales on the straight edge thereof, and is characterized in that the geometric template is arranged on a protractor body. The protractor body is also provided with a small ruler, and the small ruler is provided with small holes with identical sizes for insertion of pens. The utility model has simple structure. With the size of one protractor, the utility model can be carried conveniently. Moreover, the utility model can be used for measuring angles and drawing straight lines, right-angled triangles, isosceles triangles, diamonds, rectangles, squares and circles.
Description
Technical field
The utility model relates to a kind of survey tool, and specifically a kind of protractor, ruler, geometric templates, compasses of collecting is the multi-function protractor of one.
Background technology
At present, people in daily life, work or study, the contact picture or measure an object angle, draw straight line, draw geometric figure such as right angled triangle or quadrangle etc., need carry a plurality of instruments, very inconvenient, particularly to primary and secondary students, increased a lot of burdens especially.Application number is 02230625.0 utility model, and disclosing a kind of protractor, ruler, quadrangle, triangle, compasses of collecting is the multi-function protractor of one.It mainly by device body, adjustable rule, estimate table, the compasses part is bonding or fixedly lock fixedly form, the device body comprises ruler and set square.It carries inconvenience, structure neither be very simple.
Summary of the invention
The purpose of this utility model provides a kind of multi-function protractor easy to carry, simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: it is a semicircular protractor, and the straight flange edge is a rule, it is characterized in that at protractor geometric templates being arranged on one's body.
Above-mentioned geometric templates is right angled triangle, isosceles triangle, rhombus, rectangle, square template.
Also have a down scale chi on one's body at protractor, the aperture of the inserted pencil of equidimension is arranged on the down scale chi.
The utility model has following advantage compared with prior art:
It is simple in structure, has only a protractor size, so easy to carry.Its energy point of view, picture straight line, right angled triangle, rhombus, isosceles triangle, quadrangle, circle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is Fig. 1 vertical view.
Among the figure, 1. semicircular protractor, 2. rule, 3. right angled triangle template, 4. isosceles triangle template, 5. rhombus template, 6. rectangle template, 7. square template, 8. down scale chi, 9. aperture.
The specific embodiment
In the drawings, the utility model is made up of semicircular protractor 1, and the straight flange edge is a rule 2, at protractor geometric templates is arranged on one's body, and geometric templates is right angled triangle template 3, isosceles triangle template 4, rhombus template 5, rectangle template 6, square template 7.With geometric templates just can draw right angled triangle, rectangle etc.Also have a down scale chi 8 on one's body at protractor, the aperture 9 of the inserted pencil of equidimension is arranged on the down scale chi 8, insert the aperture 9 on the head of down scale chi 8 with tingle, pencil inserts other aperture 9 Propelling pencil with sharpener in cap circle of required size that just can draw.
