[0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it belongs to a kind of formal science. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics. In the development of human history and social life, mathematics also plays an irreplaceable role and is an essential basic tool for learning and researching modern science and technology.

[0003] Based on the above, the inventor found that the existing auxiliary teaching device for mathematics teaching mainly has the following deficiencies. For example, when teaching mathematics, various shaped patterns need to be drawn on the blackboard. Especially when drawing triangles and circles, a large compass needs to be used to draw on the blackboard. When using the large compass, it needs to rotate 360 degrees. During the rotation, the contact between the chalk and the blackboard is unstable, resulting in the drawn pattern being prone to being intermittent. Moreover, the triangular ruler for drawing straight lines and triangles has no place to be stored after use, which is not convenient for teachers to teach mathematics. Summary of the Invention

[0025] Based on the above embodiments, the specific working principle is as follows: Use the sliding block 41 to slide in the chute 3 to adjust the painting position on the blackboard 2. Then, swing the telescopic rod 42 to make the sliding block 41 rotate, and stretch the telescopic rod 42 upward to position the circle-drawing position of the automatic compass device 43. Finally, draw a circle through the automatic compass device 43. Then, use the painting device 434 to be clamped in the slide rail 433 to adjust the radius of the drawn circle. Then, drive the support plate 432 to rotate through the driving device 431, so that the painting device 434 can fit on the blackboard 2 for automatic circle-drawing action. Then, use the servo motor a3 to drive the fixed shaft a2 to rotate through gears, so that the support plate 432 connected to the fixed shaft a2 can also rotate accordingly, and then make the painting device 434 contact the blackboard 2 for drawing a circle. The chalk and triangular ruler can also be stored in the storage basket 5.

[0026] Embodiment 2: Please refer to Figures 5 - 7 , the specific embodiments of the present invention are as follows: The painting device 434 includes a fixed seat s1, a mounting seat s2, a pull rod s3, a return spring s4, and a piece of chalk s5. The fixed seat s1 is clamped and installed on the inner end face of the slide rail 433. The mounting seat s2 is movably clamped inside the fixed seat s1. The pull rod s3 is fixedly connected to the end face of the mounting seat s2 and passes through the fixed seat s1. The return spring s4 is installed on the inner end face of the fixed seat s1. The piece of chalk s5 is inserted and installed inside the mounting seat s2. The return spring s4 is movably engaged with the end face of the mounting seat s2, which is beneficial to installing the piece of chalk s5 inside the fixed seat s1. Then, the return spring s4 presses against the end face of the mounting seat s2, enabling the piece of chalk s5 to be in contact with the end face of the blackboard 2 for drawing a circle.

[0027] The mounting seat s2 includes a mounting body s21, an inner groove s22, a protective block s23, and a stabilizing cover s24. The mounting body s21 is clamped and installed on the inner end face of the fixed seat s1 and is fixedly connected to the pull rod s3. The inner groove s22 is located on the inner end face of the mounting body s21. The protective block s23 is arranged inside the inner groove s22. The stabilizing cover s24 is clamped and installed on the outer end face of the mounting body s21.
