Abstract

The utility model discloses a multifunctional mathematics ruler. The multifunctional mathematics ruler is characterized in that one end of an upper plate and one end of a lower plate are connected through a hinged shaft, a half-round groove is formed in one end of the lower plate, a transparent protractor is arranged inside the half-round groove, and the circle center of the transparent protractor and the circle center of the half-round groove are connected together through a rotating shaft. According to the arrangement, the multifunctional mathematics ruler combines stationeries frequently used together, solves the problem that users need to use the various stationeries during study and work, can be widely used by students, saves the drawing time for the students and improves the drawing efficiency. The multifunctional mathematics ruler is small in size and convenient to use and carry.

Description

Multifunctional mathmatical ruler

Technical field

The utility model relates to a kind of stationery, is a kind of multifunctional mathmatical ruler specifically.

Background technology

Current known student mostly is each self-separation with the mapping apparatus, and function singleness, as ruler, set square, figure slide calliper rule and polygon drawing ruler etc., during use, changes frequently, gives using and carrying and make troubles of student.

Summary of the invention

The purpose of this utility model is that a kind of multi-functional mathmatical ruler that has is provided.

To achieve these goals, one end of upper plate of the present utility model and lower plate is linked together by jointed shaft, be provided with the parallelogram, isosceles right triangle, equilateral triangle hollow out of hollow out and with the triangle at 30 ° of angles on the surface of upper plate, the examination that is provided with hollow out on the surface of lower plate is coated with slide calliper rule, circle, regular hexagon and square, semi-circular recesses is located at an end of lower plate, be provided with the amount transparent hornwork in semi-circular recesses, the center of circle of amount transparent hornwork and the center of circle of semi-circular recesses are linked together by rotating shaft.

By above setting, the utility model organically combines various stationery commonly used, has solved the user and use the loaded down with trivial details of various stationery in study and work, can be widely used in, in student's use, having saved student's the mapping time, has improved mapping efficiency.The utility model volume is little, uses easy to carry.

The accompanying drawing explanation

Now the utility model is described in further detail by reference to the accompanying drawings.

Fig. 1 is structural representation of the present utility model.

In figure: 1, upper plate, 2, lower plate, 3, jointed shaft, 4, parallelogram, 5, isosceles right triangle, 6, equilateral triangle hollow out, 7, with the triangle at 30 ° of angles, 8, examination is coated with slide calliper rule, 9, circle, 10, regular hexagon, 11, square, 12, semi-circular recesses, 13, the amount transparent hornwork.

The specific embodiment

As shown in Figure 1, one end of upper plate 1 of the present utility model and lower plate 2 is linked together by jointed shaft 3, be provided with the parallelogram 4, isosceles right triangle 5, equilateral triangle hollow out 6 of hollow out and with the triangle 7 at 30 ° of angles on the surface of upper plate 1, the examination that is provided with hollow out on the surface of lower plate 2 is coated with slide calliper rule 8, circle 9, regular hexagon 10 and square 11, semi-circular recesses 12 is located at an end of lower plate 2, be provided with amount transparent hornwork 13 in semi-circular recesses 12, the center of circle of the center of circle of amount transparent hornwork 13 and semi-circular recesses 12 is linked together by rotating shaft.By above setting, the utility model can draw different figures according to the Students ' Learning needs, rotation amount transparent hornwork 13, but the number of degrees of measured angular.While not using, upper plate 1 and lower plate 2 realize folding by jointed shaft 3, reduced and taken up room, and are easy to carry.
