Figure 4 This diagram illustrates the usage of the ruler in the second embodiment of the present invention for multifunctional mathematical learning. Figures 1-4 As shown, this utility model provides a multifunctional math learning ruler, comprising:

[0035] First scale 10, second scale 20 and substrate 30;

[0036] The substrate 30 includes a first groove 301 and a second groove 302, the first groove 301 and the second groove 302 are arranged side by side and are interconnected.

[0037] There is a gap between the two ends of the first groove 301 and the edge of the substrate 30. The first groove 301 is used to install the first scale 10. The two ends of the second groove 302 extend to the edge of the substrate 30. The second groove 302 is used to install the second scale 20. The second scale 20 is slidably connected to the second groove 302 so that the second scale 20 can move axially relative to the first scale 10.

[0038] Multiple first numbers 1011 and first scale lines 1012 are provided on the circumferential sidewall of the first scale 10. The multiple first scale lines 1012 are axially spaced apart, and a first number 1011 is provided at the bottom of each first scale line 1012.

[0039] On the circumferential sidewall of the second scale 20, there are multiple second numbers 2011, second scale lines 2012 and arrows 2013. The multiple second scale lines 2012 are axially spaced apart. Each second scale line 2012 has a second number 2011 at its bottom and an arrow 2013 at its bottom.

[0040] The spacing between the multiple first scale lines 1012 and the multiple second scale lines 2012 is the same.

[0041] Specifically, the first ruler 10 and the second ruler 20 are set as cuboids, and the cross-section of the cuboids is square. At the same time, the first ruler 10 and the second ruler 20 have the same height and the same size, which makes them convenient to use.

[0042] By providing a first groove 301 on the substrate 30, the first groove 301 can be used for mounting the first scale 10. A second groove 302 is also provided on the substrate 30, which allows the second scale 20 to move axially within the second groove 301. A first number 1011 and a first scale line 1012 are provided on the first scale 10, and a second number 2011, a second scale line 2012, and an arrow 2013 are provided on the second scale 20. The alignment indication of the contents on the second scale 20 is achieved by the movement and displacement of the second scale 20 relative to the first scale 10.

[0043] Furthermore, the first scale line 1012 and the second scale line 2012 include long scale lines and short scale lines. The length of the long scale line is greater than the length of the short scale line, and a short scale line is set between every two long scale lines. The distance between each long scale line and the short scale line is the same, so as to realize length measurement.

[0044] Furthermore, the first scale line 1012 and the second scale line 2012 may also include a middle scale line. A middle scale line is set between every two long scale lines, and four short scale lines are set between each middle scale line and a long scale line, which can realize the measurement of "centimeter".

[0045] The first digit 1011 and the second digit 2011 are respectively set on each plane of the first scale 10 and the second scale 20, and the first scale 10 and the second scale 20 have the same type of first digit 1011 and second digit 2011.

[0046] With this configuration, the first ruler 10 and the second ruler 20 can be used alone to measure length and have the function of a "ruler". When the first ruler 10 and the second ruler 20 are mounted on the base plate 30, the alignment indication of different contents can be achieved by sliding the second ruler 20 back and forth.

[0047] Furthermore, an infrared spotlight (not shown in the figure) is provided on the side wall of the first scale 10 or the second scale 20 along the axial direction. A battery (not shown in the figure) is installed inside the first scale 10 or the second scale 20 where the infrared spotlight is provided. The battery is electrically connected to the infrared spotlight. With this configuration, the teacher can use the infrared spotlight for remote teaching assistance.

[0048] A switch (not shown in the figure) and a charging interface (not shown in the figure) are also provided on the first scale 10 or the second scale 20 for setting the battery. The battery can be charged through the charging interface, and the infrared spotlight can be turned on or off through the switch, which is convenient for repeated use.

[0049] Furthermore, a third groove (not shown in the figure) is provided on the circumferential side wall of the first scale 10 or the second scale 20. A bubble level is installed in the third groove, and a sealing cover (not shown in the figure) is provided on the top of the third groove to seal the internal space of the third groove.

[0050] In summary, by providing a first groove 301 and a second groove 302 on the substrate 30, the first groove 301 is equal in length to the first scale 10, the two ends of the second groove 302 extend to the edge of the substrate 30, and the second groove 302 is slidably connected to the second scale 20, when the first scale 10 and the second scale 20 are installed on the substrate 30, the alignment indication of the contents on the first scale 10 and the second scale 20 can be achieved by sliding the second scale 20.
