Detailed Description

The technical scheme of the utility model is more fully explained in detail by combining the attached drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

In specific embodiment 1, a novel multipurpose combined ruler comprises a protractor 1 and a straight ruler;

the measuring range of the protractor 1 is 0-180 degrees, the bottom edge of the protractor 1 is connected with an extending edge 2, the left half part of the extending edge 2 is provided with a hollowed groove 201 comprising a circle, an ellipse and a parallelogram, the right half part of the extending edge 2 is provided with a connecting arm 3, the middle part of the extending edge 2 is provided with a fixed shaft 4, the connecting arm 3 is rotatably arranged on the fixed shaft 4, the right side end of the connecting arm 3 extends out of the right side end of the extending edge 2, and the right side end of the connecting arm 3 is symmetrically provided with a first bulge 301 along the middle part thereof;

the ruler comprises a first ruler 5 and a second ruler 6, the middle parts of the first ruler 5 and the second ruler 6 are all provided with a drawing groove 7 in a penetrating mode, the position and the length of the drawing groove 7 correspond to the scale mark positions and the lengths of the first ruler 5 and the second ruler 6, the middle part of the left side end of the drawing groove in the first ruler 5 is provided with a marking line 8, the left side end of the first ruler 5 is provided with a first groove 501 corresponding to the first protrusion 301, the right side end of the first ruler is provided with a second groove 502, and the left side end of the second ruler 6 is provided with a second protrusion 601 corresponding to the second groove 502.
