Abstract

A kind of drawing tool, comprise the set square of band protractor, the hypotenuse center of the set square with protractor is fixed with tubular rivet, in tubular rivet, pin is installed, one end of left ruler and one end of right ruler respectively perforate are arranged on pin, and the top of pin is fixed with pad, connects right ruler below pad, left ruler is connected, the set square of connecting band protractor below left ruler below right ruler.Set square with protractor is isosceles right angle triangle, in set square, be carved with protractor, in protractor, be provided with semicircle orifice, and protractor and set square are on same plate.Set square with protractor, left ruler and right ruler transparent organic glass make.As long as rotate two rulers during use, that just can draw as required finds applicable angle, then uses pen along the picture angle, limit of ruler.The utility model can help teacher or engineer to map easily, and numerical value is very accurate, also can work as a common ruler simultaneously and use.

Description

A kind of drawing tool
Art
The utility model relates to a kind of stationery, relates in particular to a kind of a kind of drawing tool two rulers and set square protractor being combined dexterously the mapping of energy fast and easy.
Background technology
On mathematics class and physics lesson, teacher often will use the instrument mapping at picture angle, and some instrument is too heavy, causes teacher to draw very difficult, therefore inaccuracy, is easy to occur error.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art part, provides a kind of a kind of drawing tool two rulers and set square protractor being combined dexterously the mapping of energy fast and easy.
The utility model solves the technical scheme that its technical problem adopts: a kind of drawing tool, comprise the set square of band protractor, the hypotenuse center of the set square with protractor is fixed with tubular rivet, in tubular rivet, pin is installed, one end of left ruler and one end of right ruler respectively perforate are arranged on pin, and the top of pin is fixed with pad, connects right ruler below pad, left ruler is connected, the set square of connecting band protractor below left ruler below right ruler.Set square with protractor is isosceles right angle triangle, in set square, be carved with protractor, in protractor, be provided with semicircle orifice, and protractor and set square are on same plate.Set square with protractor, left ruler and right ruler transparent organic glass make.
The beneficial effects of the utility model are, the utility model is the instrument that a kind of fast and easy draws angle mapping, and teacher or engineer can be helped to map easily, and numerical value is very accurate, also can work as a common ruler simultaneously and use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 be embodiment one of the present utility model face junction structure figure.
Fig. 2 is the side-looking structure chart of embodiment one of the present utility model.
Fig. 3 is the set square figure of the band protractor of embodiment one of the present utility model.
In figure: 1. left ruler, 2. right ruler, be 3. with the set square of protractor, 4. pad, 5. pin, 6. tubular rivet, 7. semicircle orifice.
Detailed description of the invention
Fig. 1, Fig. 2, embodiment illustrated in fig. 3 in, be provided with left ruler (1), right ruler (2), set square (3) with protractor, pad (4), pin (5), tubular rivet (6), semicircle orifice (7).
Implement a kind of drawing tool of the present utility model, comprise the set square (3) of band protractor, the hypotenuse center of the set square (3) with protractor is fixed with tubular rivet (6), pin (5) is installed in tubular rivet (6), one end of left ruler (1) and one end of right ruler (2) respectively perforate are arranged on pin (5), the top of pin (5) is fixed with pad (4), pad (4) connects right ruler (2) below, right ruler (2) connects left ruler (1) below, the set square (3) of connecting band protractor below left ruler (1).Set square (3) with protractor is isosceles right angle triangle, in set square, be carved with protractor, is provided with semicircle orifice (7) in protractor, and protractor and set square are on same plate.Set square (3) with protractor, left ruler (1) and right ruler (2) make of transparent organic glass.
Implementing the utility model, is a kind of drawing tool being convenient to draw fast angle.The material that the utility model uses to be two angles of two rulers and one piece of built-in protractor the be isosceles right angle triangle of 45 degree, by one end perforate of two rulers, on the central point of set square hypotenuse, fixation hollow rivet, then couples together with pin.The set square of two rulers and band protractor all adopts clear perspex material, as long as rotate two rulers during use, that just can draw as required finds applicable angle, then use pen along the picture angle, limit of ruler, so just can draw angle easily and fast, exactly, also can work as a common ruler simultaneously and use.
