Abstract
A drawing tool comprises a set square with an angle gauge. A hollow rivet is fixed to the center of a beveled edge of the set square with the angle gauge, a pin is installed in the hollow rivet, one end of a left ruler and one end of a right ruler are respectively provided with a hole and installed on the pin, a gasket is fixed at the top end of the pin, the lower side of the gasket is connected with the right ruler, the lower side of the right ruler is connected with the left ruler, and the lower side of the left ruler is connected with the set square with the angle gauge. The set square with the angle gauge is an isosceles right-angle set square, the interior of the set square is engraved with the angle gauge, a semicircular hole is formed in the angle gauge, and the angle gauge and the set square are on the same plate. The set square with the angle gauge, the left ruler and the right ruler are made of transparent organic glass. When the drawing tool is used, a proper angle can be found according to content to be drawn as long as the two rulers are rotated, and angles are then drawn along the edges of the rulers with a pencil. Teachers or engineers can draw graphs easily with the help of the drawing tool, numerical values are very precise, and meanwhile the drawing tool can be used as a common ruler.
Description
Affiliated technical field
The present invention relates to a kind of stationery, relate in particular to a kind of by two rulers and set square protractor combine dexterously can fast and easy mapping a kind of drawing tool.
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, and therefore inaccuracy, is easy to occur error.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of two rulers and set square protractor are combined to a kind of drawing tool that energy fast and easy is mapped dexterously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of drawing tool, comprise the set square with protractor, the hypotenuse center of the set square with protractor is fixed with tubular rivet, pin is installed in tubular rivet, 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, connect right ruler below pad, below right ruler, connect left ruler, the set square of connecting band protractor below left ruler.Set square with protractor is isosceles right angle triangle, is carved with protractor in set square, is provided with semicircle orifice in protractor, and protractor and set square are on same plate.Set square with protractor, left ruler and right ruler are made of transparent organic glass.
The invention has the beneficial effects as follows, the present invention is the instrument that a kind of fast and easy is drawn angle mapping, can help teacher or engineer to map easily, and numerical value is very accurate, also can work as a common ruler simultaneously and use.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 be embodiments of the invention one face junction structure figure.
Fig. 2 is the side-looking structure chart of embodiments of the invention one.
Fig. 3 is the set square figure with protractor of embodiments of the invention one.
In figure: 1. left ruler, 2. right ruler, the 3. set square with 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 invention, comprise the set square (3) with 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 one end of left ruler (1) and right ruler (2) respectively perforate is 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, left ruler (1) is the set square of connecting band protractor (3) below.Set square (3) with protractor is isosceles right angle triangle, is carved with protractor in set square, 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) are made of transparent organic glass.
Implementing a kind of drawing tool of the present invention, is a kind of drawing tool that can be convenient to draw fast angle.The material that the present invention uses is the isosceles right angle triangle that two angles of two rulers and a built-in protractor are 45 degree, and by one end perforate of two rulers, fixation hollow rivet on the central point of set square hypotenuse, then couples together with pin.Two rulers all adopt transparent organic glass material with the set square with protractor, when use, need only and rotate two rulers, that just can draw as required finds applicable angle, then use the picture angle, limit of pen along ruler, so just can be easily and fast, drawn angle exactly, also can work as a common ruler use simultaneously.
