Abstract

The utility model object is exactly the function singleness, the awkward defect that exist to overcome existing set square, there is provided one not only can draw all kinds of geometric figure and also can angulation, amount arc, draw angle, draw arc, make students in middle and primary schools can make figure rapidly, accurately in the process of doing one's assignment, improve the multi-functional positive set square of operation quality and learning efficiency.The technical solution of the utility model is: a kind of multi-functional positive set square, and this set square is equilateral triangle, on have length scale 1.There is circular hole 3 center.Be that the center of circle draws angle index line 2 with center hole, with circular hole 4 on graduation mark, and go out angle number of division value at each limit subscript.

Description

Multi-functional positive set square
Technical field:
The utility model relates to Students ' Learning articles for use field, relates in particular to a kind of multi-functional positive set square.
Background technology:
Set square is students in middle and primary schools' one of indispensable stationery in daily study, and on market existing set square mainly two pieces of its drift angles be respectively 30 degree, 60 degree, 90 degree and 45 degree, 45 degree, 90 degree.For the geometric figure of more complicated, when students in middle and primary schools do geometric operations, usually also must be equipped with compasses, curve ruler etc., just can complete various geometric figure and make, which not only adds expense and carry very inconvenient.Therefore, the set square inventing a kind of multi-functional equilateral triangle is significantly.
Utility model content:
The utility model object is exactly to overcome the function singleness that existing set square exists, the defect using inconvenience, there is provided one not only can draw all kinds of geometric figure and also can angulation, amount arc, make students in middle and primary schools can make figure rapidly, accurately in the process of doing one's assignment, improve the multi-functional positive set square of operation quality and learning efficiency.
The utility model achieves the above object by following technical solution: a kind of multi-functional positive set square, is characterized in that: this set square is equilateral triangle, on have length scale 1.There is circular hole 3 center.Be that the center of circle draws angle index line 2 with circular hole, with circular hole 4 on graduation mark, and go out angle number of division value at each limit subscript.
The utility model has the advantages that: owing to laying the function adding tolerance angle on multi-functional positive set square, use it directly can draw round picture arc and draw angle and measuring angle line, student is enable to make figure quickly and accurately when doing one's assignment, measure numerical value, greatly increase operation quality and learning efficiency.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation; Wherein 1 length scale, 2 angle indexs, 3 center holes, 4 graduation mark circular holes.
Detailed description of the invention:
As shown in Figure 1, the present embodiment adopts the set square of an equilateral triangle as substrate, and the set square of this specification is best suited for students in middle and primary schools and draws and measure use.
Refer to Fig. 1: equilateral triangle set square is provided with length scale, with the center of set square for the center of circle draws angle index line to each limit, and be marked with corresponding angular values on each limit, every bar angle index line all has circular hole.During use, the summit of the center hole alignment angle of set square, directly can measure the number of degrees at angle.Use center hole and scale circular hole can measure the number of degrees at various angle.Utilize the mensurable straight length of length scale on set square one side.

Claims (1)

1. a multi-functional positive set square, is characterized in that: this set square is equilateral triangle, is provided with length scale, there is circular hole center, be that the center of circle draws angle index line with center hole, with circular hole on graduation mark, each limit of set square all mark angle index numerical value.
