Embodiment Construction
[0009] In the specific embodiment shown in the accompanying drawings, the multifunctional ruler is made up of two sections of rulers (3) and a rotating shaft (1), a pull wire (4), and a pen holder (5). The two sections of rulers (3) are all magnetized The iron sheet is made of iron sheet, as shown in the attached drawing, it is a ruler with a round head at one end, its size depends on the specific working conditions, one end is connected by a rotating shaft (1), and the scale body (3) is marked with a scale (2), the zero scale line is far away from the end of the rotating shaft, and there is a right-angle marking near the rotating shaft (1). The ruler bodies (3) are completely symmetrical about the angle bisectors of the included angles formed by them, and the same stay wires (4) are connected at the same positions on the outer ends of the two ruler bodies (3), and the same stay wires (4) are connected to one end of the ruler bodies (3). Pen cover (5), when this multifunctiona...

The invention provides a multifunctional ruler applied to industrial production. The multifunctional ruler comprises two sections of ruler bodies, a rotating shaft, stayguys and pen caps, wherein the two sections of ruler bodies are both made of magnetized iron sheets and are connected at one end by the rotating shaft; scales are marked on the ruler bodies; zero scale lines are positioned at the ends of the ruler bodies, which are far away from the rotating shaft; right-angle marked lines are arranged at parts of the ruler bodies, which are close to the rotating shaft, that is, when a right angle is formed by the two ruler bodies, extended lines of edges of one ruler body are positioned on trace lines on another ruler body, and the ruler bodies are fully symmetrical about an angle bisector of an included angle formed by the ruler bodies; the identical stayguys are connected to the same positions of the outer ends of the two ruler bodies; and one end of each stayguys is connected with the identical pen caps. When the multifunctional ruler is in use, lengths can be measured or right angles can be drawn according to the scales and the right-angle marked lines, and after chalks are loaded in the pen caps of the ruler, circular arcs are drawn through two straightened stayguys, and the intersection point of the two circular arcs and the peak of an angle to be bisected can be used to together determine the angle bisector of the angle to be bisected. By adopting the multifunctional ruler, the problems of length measurement, bisection of any angle, right-angle judging or drawing, and the like can be accurately solved; and besides, the efficiency is high, the use limits are few and the structure is simple.
Description
Technical field [0001] The invention relates to a multifunctional ruler with multiple functions used in industry, especially the multifunctional ruler with the functions of measuring length, bisecting any angle and determining right angles. Background technique [0002] In industrial production, problems such as measuring length, bisecting an arbitrary angle, judging or drawing a right angle are often encountered. Some appliances are even difficult to operate in actual production, and the work efficiency is low. Contents of the invention [0003] In order to overcome the inefficiency or difficulty in operation when various instruments are used to solve problems such as measuring length, bisecting an arbitrary angle, judging or drawing a right angle in industrial production, the present invention provides a multifunctional ruler. The multi-functional ruler can not only accurately solve problems such as measuring length, bisecting an arbitrary angle, judging or drawing a ri...
