A clamping mechanism is provided on the adjusting mechanism, which is used to clamp and fix chalk. Scales are respectively provided on the frame 5 and the mounting block 1. The scale provided on the frame 5 is convenient for measuring distances, which is beneficial to mathematics teaching. It is also convenient to cooperate with the adjusting mechanism to adjust the position of the clamping mechanism for drawing circles of different sizes. The scale provided on the mounting block 1 is coordinated with the frame 5 to facilitate measuring angles, which is beneficial to mathematics teaching.

[0021] In detail, the adjustment mechanism includes a screw rod 21, which is rotatably connected to the inner wall of the frame 5 through a bearing. The screw rod 21 is set to drive the installation frame 22 to slide along the surface of the slide rod 28. One end of the screw rod 21 passes through the surface of the frame 5. A handle 24 is fixedly installed on one end of the screw rod 21. The handle 24 is in the shape of a circular plate. The handle 24 is set to drive the screw rod 21 to rotate.

[0022] Furthermore, a horizontal plate 23 is fixedly installed on the side of the frame 5. The horizontal plate 23 is in the shape of a square plate. The horizontal plate 23 is provided to receive the installation of a spring 26. A spring 26 is fixedly installed on the horizontal plate 23. The spring 26 is provided to apply a force to the latch 27 so that the latch 27 can be inserted into the teeth on the surface of the gear ring 25, thereby achieving the purpose of fixing the screw rod 21. A latch 27 is fixedly installed on one end of the spring 26. The cross-sectional shape of the latch 27 is T-shaped. The latch 27 is provided to be inserted into the teeth on the surface of the gear ring 25, thereby achieving the purpose of fixing the screw rod 21. One end of the latch 27 passes through the horizontal plate 23. A gear ring 25 is fixedly installed on the screw rod 21. The gear ring 25 is provided to receive the insertion of one end of the latch 27, which is convenient for fixing the screw rod 21.

[0023] Furthermore, a mounting frame 22 is threadedly connected to the screw rod 21, and the mounting frame 22 is in the shape of a square frame. The setting of the mounting frame 22 is used to undertake the installation of the clamping mechanism. A slide rod 28 is fixedly installed on the inner wall of the frame body 5, and the slide rod 28 is in the shape of a cylindrical rod. The mounting frame 22 slides on the slide rod 28. The setting of the slide rod 28 serves to limit the movement of the mounting frame 22 when the screw rod 21 drives the mounting frame 22 to move, which is beneficial to the linear movement of the mounting frame 22.

[0024] In more detail, the clamping mechanism includes a threaded rod 31, which is threadedly connected to the side of the mounting frame 22. The threaded rod 31 is configured to drive the first clamping plate 33 to move linearly along the inner wall of the mounting frame 22, and cooperate with the second clamping plate 32 to facilitate clamping and fixing the chalk.

[0025] In general, one end of the threaded rod 31 passes through the mounting frame 22, and one end of the threaded rod 31 is rotatably connected to the first clamping plate 33 through a bearing. The first clamping plate 33 slides on the inner wall of the mounting frame 22. The setting of the first clamping plate 33 cooperates with the second clamping plate 32 to facilitate clamping and fixing the chalk.

[0026] Finally, a second clamping plate 32 is fixedly installed on the inner wall of the mounting frame 22. The opposing surfaces of the first clamping plate 33 and the second clamping plate 32 are both arc surfaces. The first clamping plate 33 and the second clamping plate 32 are arranged to clamp and fix the chalk so that the chalk can be used to draw a circle.

[0027] Working method: When working, place the chalk between the first clamping plate 33 and the second clamping plate 32, and then rotate the threaded rod 31. The threaded rod 31 drives the first clamping plate 33 to move linearly along the inner wall of the mounting frame 22. During the movement, the first clamping plate 33 cooperates with the second clamping plate 32 to facilitate clamping and fixing the chalk.

[0028] After the chalk is clamped and fixed, the teaching aid is placed on the designated center of the circle through the positioning hole 4, and then the latch 27 is pulled as required to pull one end of the latch 27 away from between the teeth of the gear ring 25, and then the handle 24 is turned. The handle 24 drives the screw rod 21 to rotate, and the screw rod 21 drives the mounting frame 22 to slide linearly along the surface of the slide rod 28. When the mounting frame 22 slides, it will drive the chalk to move linearly, in conjunction with the scale on the surface of the frame 5, until the chalk moves to the appropriate position, and then release the latch 27. The latch 27 will be inserted into the teeth on the surface of the gear ring 25 under the action of the spring 26, thereby achieving the purpose of fixing the screw rod 21 and the mounting frame 22, and then press the mounting block 1 and rotate the frame 5 with the mounting block 1 as the center. The frame 5 will drive the chalk to perform cylindrical motion, thereby achieving the purpose of drawing a circle, which is beneficial to mathematical thinking training.

[0029] In addition, the frame 5 is provided with a scale, which is convenient for measuring distance and is beneficial to mathematics teaching. It is also convenient to cooperate with the adjustment mechanism to adjust the position of the clamping mechanism for drawing circles of different sizes. The mounting block 1 is provided with a scale, which cooperates with the frame 5 to facilitate measuring angles and is beneficial to mathematics teaching.
