Abstract
The utility model relates to a multifunctional triangular ruler. A cone (1) is fixedly arranged on the ruler plane; the axis of the cone (1) is perpendicular to the ruler plane and passes through one of the vertexes (O) of the triangular ruler; a group of length scales (2) are arranged on the ruler plane and through pen tip inserting holes are respectively formed on the length scales, wherein one of the vertexes (O) is used as the beginning point of the length scales (2); a group of angle scales (3) are arranged at a ruler side opposite to one of the vertexes (O), wherein one of the vertexes (O) is used as the top point and the other ruler side is used as the zero scale of the angle scales (3); and a group of through card coloring holes (4) in match with an answer sheet are arranged on the ruler plane. The multifunctional triangular ruler disclosed by the utility model solves the problem that a conventional triangular ruler is single in function.
Description
Technical field
The utility model relates to a kind of stationery, is specifically related to a kind of set square.
Background technology
Set square is a kind of stationery commonly used.Existing set square mostly is greatly right angled triangle, can be used for drawing the angle of line segment, right angle and particular degree, some is arranged also with protractor, on the whole, and simple in structure, function singleness.
The utility model content
Technical problem to be solved in the utility model is that a kind of multi-functional triangular ruler is provided.Use this set square can draw multiple radius circle, draw at any angle angle, can also be used for filling answer sheets, to solve the problem of existing set square function singleness.
In order to solve this technical problem, the utility model by the following technical solutions:
A kind of multi-functional triangular ruler is characterized in that: be fixedly installed a cone at the chi face, the axis of this cone and chi face are perpendicular, and described axis is crossed one of them summit of set square; The set square face be provided with one group take described one of them summit as starting point the length scale and on corresponding length scale, offering respectively penetrating nib jack; Be provided with one group take described one of them summit as the summit and the angle index take another bar rule limit as zero graduation on the chi limit relative with described one of them summit; Be provided with one group of penetrating card painting hole that is complementary with answering card at the chi face.
Good effect of the present utility model is:
The utility model multi-functional triangular ruler has following functions: 1, only need the spur of described cone is inserted on the paper, corresponding required radius length injects corresponding nib jack with nib, around described spur rotation nib, can draw the circle of certain radius; 2, a limit along set square draws a ray, and this ray summit is stuck in the spur place, needs the graduation mark of picture angle on the ray alignment angles scale, draws another limit along the zero groove of angle index, can draw at any angle angle.One group of card painting hole that is complementary with answering card is set on the set square face, then can be in examination filling answer sheets more easily, and be unlikely to be coated onto the frame exterior domain.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, present embodiment is a kind of drawing square, be fixedly installed a cone 1 at the chi face, the axis of this cone 1 and chi face are perpendicular, and described axis is crossed summit, the right angle O of set square, the cone point of cone 1 is as spur, and this spur is pressed in paper as home position when drawing circle (or circular arc) line.The set square face be provided with one group take described right angle summit O as starting point length scale 2 and on corresponding length scale, offering respectively penetrating nib jack, the nib that inserts when drawing circle (or circular arc) rotates around spur and gets final product.
Be provided with on the chi limit of hypotenuse one group take described one of them summit O as the summit and the angle index 3 take another bar rule limit as zero graduation.Take a right-angle side as the angle a limit, and the outer end points of connect Vertex O and respective angles scale 3 can draw the angle of required angle.
Be provided with one group of penetrating card painting hole 4 that is complementary with answering card at the chi face.
Claims (1)
1. multi-functional triangular ruler, it is characterized in that: be fixedly installed a cone (1) at the chi face, axis and the chi face of this cone (1) are perpendicular, and described axis is crossed one of them summit (O) of set square; The set square face be provided with one group take described one of them summit (O) as starting point length scale (2) and on corresponding length scale, offering respectively penetrating nib jack; Be provided with one group of angle index (3) on the chi limit relative with described one of them summit (O); Be provided with one group of penetrating card painting hole (4) that is complementary with answering card at the chi face.
