Abstract
A ruler for students comprises a 360-degree protractor. A cross slab is arranged in the middle of the protractor; the upper end and the lower end of the cross slab are provided with scales; and the surface of the cross slab is provided with an isosceles right-angled triangle through hole I and a 30-degree right-angled triangle through hole II. When the ruler is used, the 360-degree protractor facilitates students measuring the degree of angles; the cross slab can act as a straight scale; and the isosceles right angled triangle through hole I and the 30-degree right angled triangle through hole II on the surface of the cross slab can act as a set square. The ruler for the students has the advantages of being simple in structure and convenient to use, integrating multiple functions into a whole and being more convenient for the students to use.
Description
Technical field the utility model relates to a kind of stationery, and especially a kind of student uses chi.
Background technology is well-known, existing student is varied with chi, but its function singleness, the use needs of students can not have been satisfied, for example: existing student is not integrated in one 360 tolerance hornworks, ruler, isosceles right triangle, 30 degree right angled triangles with chi, has brought inconvenience to students.
The summary of the invention the purpose of this utility model is to provide a kind of student that 360 tolerance hornworks, ruler, isosceles right triangle, 30 degree right angled triangles are integrated in one to use chi.
The utility model comprises 360 tolerance hornworks, and the place is provided with transverse slat in the protractor centre position, and is equipped with scale at the two ends up and down of transverse slat; Be provided with isosceles right triangle open-work one and 30 degree right angled triangle open-works two on the surface of transverse slat.
After adopting said structure, during use, 360 tolerance hornworks make things convenient for the number of degrees of students measured angular; Transverse slat can be brought into play the function of ruler; The isosceles right triangle open-work one on transverse slat surface and 30 degree right angled triangle open-works two can be brought into play the function of set square.
The utility model has the advantages that: simple in structure, easy to use, multiple function is integrated in one, bring greater convenience for the use of students.
Description of drawings Fig. 1 is a schematic perspective view of the present utility model.
The specific embodiment with in the schematic perspective view of chi, comprises 360 tolerance hornworks 1 student shown in Figure 1, and the place is provided with transverse slat 2 in the protractor centre position, and is equipped with scale 3 at the two ends up and down of transverse slat; Be provided with isosceles right triangle open-work one 4-1 and 30 degree right angled triangle open-works, two 4-2 on the surface of transverse slat.
