[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As in the background art, existing rulers and other similar tools are generally designed with a split structure, which makes them inconvenient to carry and use.

[0029] To solve this technical problem, this utility model provides a mathematical teaching tool that is applied to mathematical teaching tools.

[0030] For details, please refer to Figures 1-3 Mathematical teaching aids specifically include:

[0031] Ruler 1 and Ruler 2 are arranged parallel to each other vertically. One end of Ruler 2 is rotatably connected to Ruler 1. An observation window 3 is provided at the end of Ruler 2 connected to Ruler 1. An angle code 4 is provided at the end of Ruler 1 connected to Ruler 2. The angle code 4 is located inside the observation window 3.

[0032] The end of ruler body 1 away from angle code 4 is fixedly connected with anti-slip rubber strip 6, and the lower end of ruler body 2 away from observation window 3 is provided with spring clip 5, which is fastened to the anti-slip rubber strip 6.

[0033] The mathematical teaching aid provided by this utility model, through the structural design of ruler body 1 and ruler body 2, allows the device to be used as a ruler before unfolding, and after unfolding, it can be used for drawing at different angles according to the drawing needs, thereby effectively improving the ease of use of the device. In addition, the overall structure is flexible, can be folded, and is easy to carry.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figures 1-4 A mathematical teaching aid, comprising:

[0037] Ruler 1 and Ruler 2 are arranged parallel to each other vertically. One end of Ruler 2 is rotatably connected to Ruler 1. An observation window 3 is provided at the end of Ruler 2 connected to Ruler 1. An angle code 4 is provided at the end of Ruler 1 connected to Ruler 2. The angle code 4 is located inside the observation window 3. A pointer 14 is fixedly connected inside the observation window 3 for indicating the rotation angle.

[0038] It can be seen that through the rotating connection of ruler body 1 and ruler body 2, the teacher can unfold ruler body 1 and draw at different angles according to the coordination of angle code 4 and pointer 14. When using it, both hands unfold ruler body 1 and ruler body 2. When drawing, one hand holds the connection between ruler body 1 and ruler body 2 to keep the device in contact with the blackboard, so that the other hand can draw.

[0039] Furthermore, to achieve the folding and limiting effect of ruler body 1, an anti-slip rubber strip 6 is fixedly connected to the end of ruler body 1 away from angle code 4, and a spring clip 5 is provided at the lower end of the end of ruler body 2 away from observation window 3. The spring clip 5 is fastened to the anti-slip rubber strip 6. The anti-slip rubber strip 6 increases the friction between ruler body 1 and ruler body 2 after ruler body 1 is folded, thereby preventing ruler body 1 from accidentally sliding out. The spring clip 5 further enhances the limiting effect of ruler body 1 after folding.

[0040] Specifically, the spring clip 5 includes a housing 7, which is embedded and fixed inside the ruler body 2. A retaining bead 8 is movably connected inside the housing 7. The retaining bead 8 is located at the end of the spring clip 5 near the anti-slip strip 6. The anti-slip strip 6 has a groove that engages with the retaining bead 8. A thrust spring 9 is located inside the housing 7 at the end furthest from the retaining bead 8. Therefore, after the ruler body 1 is folded, the retaining bead 8 engages with the groove on the anti-slip strip 6, thus limiting the rotation of the ruler body 1. The thrust spring 9 applies a continuous thrust to the retaining bead 8, thereby maintaining the engagement between the retaining bead 8 and the groove.

[0041] Example 2:

[0042] The mathematical teaching aids provided in Example 1 are further optimized, specifically, as follows: Figure 5 As shown, ruler body 2 includes a ruler body 10 and a ruler body 11. The ruler body 10 and the ruler body 11 are both provided with scales on the sides that are far apart from each other.

[0043] Furthermore, in order to achieve the folding of the two-piece split 11, a storage cavity 12 is provided on the side of the two-piece main body 10 near the two-piece split 11. The two-piece split 11 is located inside the storage cavity 12, and the end of the two-piece split 11 away from the observation window 3 is rotatably connected to the two-piece main body 10.

[0044] Furthermore, in order to achieve rotational limiting of the 11 split body of the 11, a limiting knob 13 is provided at the connection between the 10 main body of the 11 and the 11 split body of the 11. The limiting knob 13 is rotatably connected to the 11 split body of the 11 and threadedly connected to the 10 main body of the 11.

[0045] With the above structural design, the scales set on the sides of the main body 10 and the split body 11 of the ruler can facilitate drawing straight lines on both sides of the ruler body 2. By loosening the limiting knob 13, the split body 11 of the ruler can be unfolded 180°, so that longer straight lines can be drawn.
