In order to achieve the above object, the utility model adopts the following technical scheme:
the multifunctional ruler comprises a ruler plate, linear scales, a central hole, a centimeter-level arc hole and a millimeter-level arc hole;
the ruler plate is a transparent flat plate;
the linear scale is provided with length scale marks along the upper edge line of the scale plate, and the scale marks are accurate to one millimeter;
the circle center hole is arranged on the ruler plate, a plurality of centimeter-level arc holes are arrayed to the right side by taking the circle center hole as an original point, the distance between two adjacent centimeter-level arc holes is one centimeter, and the distance between the circle center of the circle center hole and the circle center of the centimeter-level arc hole adjacent to the circle center hole is one centimeter;
the plurality of millimeter-scale circular arc holes are arrayed to the left side by taking the central hole as an original point, the distance between two adjacent millimeter-scale circular arc holes is one millimeter, and the distance between the circle center of the central hole and the circle center of the millimeter-scale circular arc hole adjacent to the central hole is one millimeter.
Furthermore, the other side of the linear scale relative to the ruler plate is provided with a wavy edge, and wavy lines can be drawn by utilizing the wavy edge.
Furthermore, a magnifier is arranged on the ruler plate, and tiny elements such as figures and characters are magnified by the magnifier.
Further, the ruler plate is provided with a circular groove with one degree taking the central hole as the circle center, the circular groove is matched with angle scales and angle numerical values, and the angle can be measured conveniently.
Further, the left side and the right side of the ruler plate are provided with parallel scale marks, and a plurality of parallel straight lines at intervals can be drawn quickly by using the parallel scale marks.
The utility model has the advantages that:
the ruler can draw line segments and measure the length by arranging the linear scale at the upper edge line of the ruler plate; the ruler plate is provided with a plurality of centimeter-level arc holes in an array manner from the center hole serving as an original point to the right side, and the ruler plate is provided with a plurality of millimeter-level arc holes in an array manner from the center hole serving as an original point to the side; when the circular arc needs to be drawn, the first pencil penetrates through the center hole and abuts against the circle center, the mechanical pencil penetrates through the centimeter-level circular arc hole or the millimeter-level circular arc hole, the mechanical pencil draws a circle around the center hole, and the effect that the single ruler can be used for drawing the circular arc is achieved.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.
As shown in fig. 1, the multifunctional ruler comprises a ruler plate 10, a linear scale 30, a central hole 40, a centimeter-level arc hole 50 and a millimeter-level arc hole 60;
the ruler plate 10 is a transparent flat plate;
the linear scale 30 is provided with a length scale mark along the upper edge line of the ruler plate 10 and the scale mark is accurate to one millimeter;
on chi board 10 was seted up to central hole 40 is a plurality of centimetre level circular arc holes 50 of original point to the right side array, and two adjacent centimetre level circular arc holes 50's distance is a centimetre, and the distance of the centre of a circle of central hole 40 rather than the adjacent 50 centre of a circle of centimetre level circular arc holes is a centimetre.
The plurality of millimeter-scale circular arc holes 60 are arrayed to the left side by taking the central hole 40 as an original point, the distance between two adjacent millimeter-scale circular arc holes 60 is one millimeter, and the distance between the circle center of the central hole 40 and the circle center of the millimeter-scale circular arc hole 60 adjacent to the central hole is one millimeter.
The principle is as follows: the ruler can draw line segments and measure the length by arranging the straight line scale 30 at the upper side line of the ruler plate 10; by arranging the central hole 40 on the ruler plate 10, a plurality of centimeter-sized circular arc holes 50 are arrayed to the right side by taking the central hole 40 as an origin, and a plurality of millimeter-sized circular arc holes 60 are arrayed to the side by taking the central hole 40 as the origin; when the circular arc needs to be drawn, the first pencil penetrates through the central hole 40 and abuts against the circle center, the mechanical pencil penetrates through the centimeter-level circular arc hole 50 or the millimeter-level circular arc hole 60, the mechanical pencil draws a circle around the central hole 40, and the effect that the single ruler can be used for drawing the circular arc is achieved.
Further, the other side of the linear scale 30 opposite to the ruler plate 10 is provided with a wavy edge 20, and a wavy line can be drawn by using the wavy edge 20.
Further, a magnifying glass 90 is provided on the ruler plate 10, and the magnifying glass 90 is used to magnify elements such as minute figures and characters.
Further, a 180-degree circular groove 70 is formed in the ruler plate 10 by taking the central hole 40 as the circle center, and angle scales and angle numerical values are arranged in the circular groove 70 in a matched mode, so that the angle can be conveniently measured.
Further, the left side and the right side of the ruler plate 10 are both provided with parallel scale marks 80, and a plurality of parallel straight lines at intervals can be drawn quickly by using the parallel scale marks 80.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
