[0023] Please see Figures 1-4 A mathematical plotter for vocational college mathematics teachers includes a first mathematical plotting ruler 1, a second mathematical plotting ruler 2 rotatably connected to the outer surface of the first mathematical plotting ruler 1, and an adjustment mechanism 3 provided above the first mathematical plotting ruler 1.
[0024] The adjustment mechanism 3 includes two movable frames 301. The inner walls of the first mathematical drawing ruler 1 and the inner walls of the second mathematical drawing ruler 2 are slidably connected to two limiting sliders 302. The inner wall of the first mathematical drawing ruler 1 is rotatably connected to a limiting post 4. The outer surface of the limiting post 4 is rotatably connected to the inner wall of the second mathematical drawing ruler 2. By setting the limiting post 4, it is easy to limit the two mathematical drawing rulers, and it is also convenient to draw circles.
[0025] Two limiting cylinders 305 are fixedly connected to the upper surface of each limiting slider 302, and anti-slip pads 5 are fixedly connected to the bottom surface of the limiting column 4. Two anti-slip strips 6 are fixedly connected to the bottom surface of the first mathematical drawing ruler 1 and the bottom surface of the second mathematical drawing ruler 2. By setting anti-slip pads 5 and anti-slip strips 6, the friction with the teaching board can be increased, and the slippage during use can be avoided.
[0026] Each limiting cylinder 305 has a connecting post 306 slidably connected to its inner wall, and a spring 307 is fixedly connected to the outer surface of each connecting post 306. Each moving frame 301 has a threaded rod 7 threadedly connected to its inner wall, and a rotating block 8 is fixedly connected to the right end of each threaded rod 7. By setting the threaded rod 7 and the rotating block 8, it is easy to push a clamping ring 304 to move, thereby quickly completing the clamping work.
[0027] The top of each spring 307 is fixedly connected to the inner top wall of the limiting cylinder 305. A movable plate 303 is fixedly connected to the upper surface of each set of connecting columns 306. A bearing 9 is fixedly connected to the left end of each threaded rod 7. The outer surface of each bearing 9 is fixedly connected to the outer surface of the clamping ring 304. By setting the bearing 9, the threaded rod 7 can be assisted to rotate, thereby quickly assisting the threaded rod 7 to complete the clamping work.
[0028] The outer surfaces of two movable plates 303 are slidably connected to the inner wall of the first mathematical drawing ruler 1, and the outer surfaces of the other two movable plates 303 are slidably connected to the inner wall of the second mathematical drawing ruler 2. The outer surfaces of the two clamping rings 304 are fixedly connected to support columns 10. The left end of each support column 10 is fixedly connected to the inner wall of the movable frame 301. By setting the support columns 10, a clamping ring 304 can be supported and fixed, so that it can be in a stable fixed state.
[0029] The upper surface of each movable plate 303 is fixedly connected to the bottom surface of the movable frame 301. Two clamping rings 304 are slidably connected to the inner wall of each movable frame 301. An anti-slip ring 12 is fixedly connected to the inner wall of each clamping ring 304. Two pull blocks 11 are fixedly connected to the upper surface of each movable frame 301. By setting the anti-slip rings 12, the friction between the pen and the drawing pen can be increased to prevent slippage. By setting the pull blocks 11, it is convenient for the instructor to pull the movable frame 301 upwards and also convenient to move the movable frame 301.
[0030] The working principle of this utility model is as follows: When in use, the instructor first places the device in a suitable position. When it is necessary to use the device to draw a circle, the instructor pulls the moving frame 301 upwards using the pull block 11. When the instructor manually pulls the moving frame 301 upwards, the moving frame 301 can move the moving plate 303. At the same time, the moving plate 303 can move the two connecting columns 306 below upwards. During the upward movement of the connecting columns 306, they can compress the spring 307 inside the limiting cylinder 305. Under the action of compression, the spring 307 can contract upwards. Simultaneously, when the moving plate 303 is pulled up, it can separate from the two drawing rulers. Then, the instructor can pull the moving frame 301 to adjust its movement. When the movable frame 301 moves, it can drive the internal clamping structure to adjust. After adjusting to the appropriate position, the movable frame 301 is released, and the movable frame 301 and the movable plate 303 will be reset under the action of the spring 307. The instructor places the chalk or other drawing pen for drawing circles into the clamping ring 304, and then manually rotates the threaded rod 7 through the rotating block 8. With the cooperation of the bearing 9, the threaded rod 7 can quickly rotate inside the movable frame 301. At the same time, when the threaded rod 7 rotates, it can drive a clamping ring 304 to gradually move into the movable frame 301 until the drawing pen is firmly clamped. Finally, the instructor can manually press the limit post 4 and rotate the first mathematical drawing ruler 1 and the second mathematical drawing ruler 2 to draw circles.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
