[0003] At present, most common rulers on the market can provide the function of measuring and drawing straight lines, and some rulers can draw simple shapes. However, most rulers on the market lack the function of drawing coordinate lines. When students draw coordinate systems, they usually rely on the part with the function of drawing straight lines to draw coordinate lines. In this way, when drawing coordinate lines, the verticality of the X-axis and Y-axis coordinate lines needs to be grasped by students by feeling. The coordinate lines drawn in this way are not standard enough. Therefore, in order to solve the above problems, this device designs a multifunctional ruler. Utility Model Content

[0007] The above technical solution further includes: the ruler body is in a quadrilateral shape, and first scale lines are arranged on the four sides of the ruler body.
[0008] The graphic groove is any one or more combinations of quadrilateral, polygon, circle or triangle.
[0009] A second scale line is arranged on the ruler body at a side of the coordinate line groove.
[0010] The coordinate point positions are provided with two coordinate point slots.
[0011] A closing plate is fixedly mounted on the inner wall of the coordinate point slot, and the outer wall of the closing plate is parallel to the inner wall of the coordinate line slot.

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Embodiment 1
[0021] Refer to the attached Figure 1-2 The utility model provides a multifunctional ruler, including a ruler body 10, which is in a quadrilateral shape. The four sides of the ruler body 10 are all provided with first scale lines (the first scale lines are the same as the scale lines of the ruler on the market); wherein, the four sides of the ruler body 10 all have the first scale lines, which provides convenience for drawing.
[0022] The ruler body 10 is provided with a plurality of graphic grooves 20, and the graphic grooves 20 are any one or more combinations of quadrilaterals, polygons, circles or triangles; wherein, the provided graphic grooves 20 can facilitate students to draw simple geometric figures.
[0023] Two coordinate line grooves 30 are also provided on the ruler body 10. Second scale lines are provided on the side of the coordinate line grooves 30 on the ruler body 10. The two coordinate line grooves 30 are vertically crossed. A plurality of coordinate points are provided on the coordinate line grooves 30. Among them, the second scale lines are the same as the scale lines on the coordinate system. The provided coordinate line grooves 30 can be used by students to draw the coordinate system.
[0024] There are two coordinate point slots 31 at the coordinate point positions; Figure 2 As shown, the coordinate point slots 31 are provided so that students can emphasize the positions of the coordinate points by adding circles.
[0025] A closing plate 32 is fixedly installed on the inner wall of the coordinate point slot 31, and the outer wall of the closing plate 32 is parallel to the inner wall of the coordinate line slot 30; wherein, since a circular hole is opened at the coordinate point position, when drawing the coordinate line, when the brush passes through the origin position, it may cause the coordinate line to appear uneven. Therefore, in order to solve this problem, a closing plate 32 is provided on the inner wall of the coordinate point slot 31 to fill the gap position of the coordinate point slot 31, so that the flatness of the coordinate line can be guaranteed when drawing the coordinate line.
[0026] Silicone pads 33 are installed on the inner wall of the coordinate point slot 31 and the side wall of the closing plate 32 close to the coordinate point slot 31; wherein, the silicone pads 33 are fixed by bonding. When students are drawing at the coordinate point position, since the coordinate point position is an incomplete circle, the brush needs to be repeatedly drawn in the coordinate point slot 31 during drawing. Therefore, in order to avoid the sharp edge of the groove of the coordinate point slot 31 from damaging the brush during the drawing process, a silicone pad 33 is provided on the inner wall of the coordinate point slot 31, so that the silicone pad 33 can protect the brush when drawing the coordinate point.
[0027] In this embodiment, when using the multifunctional ruler of the present invention, the multifunctional ruler of the present application can provide students with the function of drawing a coordinate system, and the coordinate line grooves 30 provided make the coordinate lines drawn more standard, thereby improving the practicality of the device.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
