A method for using a drawing device for mathematical modeling comprises the following steps:

S1. First, the adjustment slot is placed on the outside of the slider, and the drawing frame is placed on the two supporting legs. At this time, the angle of the drawing frame can be adjusted so that the drawing frame is at an angle suitable for mathematical modeling personnel. After the adjustment is completed, the card block is inserted into the inside of the positioning slot under the rebound effect of the connecting spring. At this time, the card block can be prevented from shaking up and down under the connection of the connecting spring by limiting the position of the limiting telescopic plate. At the same time, the strengthening of the inclined rod and the supporting legs can complete the support of the device by cooperating with each other;

S2. After the drawing components are installed, the drawing paper is laid flat on the surface of the drawing pad. The electrostatic sticker assists the paper to be adsorbed on the surface through its own electrostatic adsorption force. By rotating the clamping plate, the magnetic plate and the magnetic block are magnetically adsorbed, and the two sides of the drawing paper can be tightly clamped, thereby completing the positioning of the drawing paper. At this time, basic patterns, such as a coordinate system, can be drawn on the surface of the drawing paper.

S3. By pulling the iron handle, the transparent drawing board is pulled outward until it is attracted by the magnetic strip. When erasing the content drawn on the surface of the transparent drawing board, the reinforcing plate is moved to slide between the inner limit rod and the outer limit rod, so that the eraser can erase the content drawn on the surface of the transparent drawing board. At this time, the drawing paper is located behind the transparent drawing board. The controller controls the multi-stage electric push rod to start, so that the position of the drawing pad can be adjusted, and then the spatial distance relationship between the basic pattern and the new drawing content can be adjusted according to the drawing requirements during mathematical modeling. When no adjustment is needed, the multi-stage electric push rod is started to extend it, so that the drawing pad and the drawing frame are completely attached, that is, the drawing paper can be completely attached to the transparent drawing board;

S4. After each drawing is completed, the controller is used to start the camera to shoot the modeled drawings, thereby realizing the storage of the drawings. In addition, during the shooting process, the controller is used to start the electric telescopic rod, which can drive the electric telescopic rod to adjust the position of the movable rod, thereby adjusting the position of the camera.

Compared with the prior art, the present invention has the following beneficial effects:

1. When in use, the electrostatic adsorption force of the electrostatic sticker can assist the paper to be adsorbed on its surface. Through the magnetic adsorption between the magnetic plate and the magnetic block, the clamping plate can tightly clamp the two sides of the drawing paper, thereby completing the positioning of the drawing paper. After drawing the basic pattern, the transparent drawing board is pulled outward by pulling the iron handle. The transparent drawing board is rolled up in the initial state. When the transparent drawing board is pulled out, the winding spring is also in a state of unfolding. The two sets of anti-slip shafts move between the corresponding inner positioning plate and the outer positioning plate, thereby achieving the benefit of making the transparent drawing board tight when stretched, which is convenient for drawing. There is no need to repeatedly draw the same basic pattern. By turning the reinforcement plate, the eraser can erase the content drawn on the surface of the transparent drawing board;

2. When in use, the controller is used to control the multi-stage electric push rod to start, so as to adjust the position of the drawing pad, and then adjust the spatial distance relationship between the basic drawing and the new drawing content according to the drawing requirements during mathematical modeling. When no adjustment is needed, the multi-stage electric push rod is started to extend it, and the drawing pad is fitted with the drawing frame, that is, the drawing paper can be fitted with the transparent drawing board. After each drawing is completed, the camera is started to shoot the modeling drawings, so as to realize the storage of the drawings. In addition, during the shooting process, the controller is used to control the start of the electric telescopic rod, so that the electric telescopic rod can drive the position of the adjustment movable rod, thereby adjusting the position of the camera, so that the shot picture is more complete;

3. When in use, each support block is installed on the outer surface of the drawing frame by using screws to complete the installation of the fixed shell, and then the adjustment slot is put on the outside of the slider, the drawing frame is mounted on the two support legs, and the drawing frame is rotated to adjust the angle of the drawing frame so that the drawing frame is at an angle suitable for mathematical modeling personnel. After the adjustment is completed, under the rebound action of the connecting spring, the card block can be driven to be inserted into the interior of the positioning slot. After the adjustment, the support legs play the role of supporting the entire device. By strengthening the support of the support legs with the diagonal rod, a stable triangular structure is formed between the support legs, the strengthening diagonal rod and the fixed bottom plate, which can effectively prevent the collapse of the device. In addition, the anti-slip pad is a hard rubber pad, which can prevent the device from sliding by itself during use.

When drawing on the surface of the transparent drawing board 102, an erasable pen needs to be used. The erasable pen can be selected from the commonly used models on the market. There is no need to repeatedly draw the same basic pattern. By toggling the reinforcement plate 11, the reinforcement plate 11 slides between the limiting inner rod 10 and the limiting outer rod 9. The eraser 12 erases the content drawn on the surface of the transparent drawing board 102. At this time, the drawing paper 306 is located behind the transparent drawing board 102. The controller 13 controls the multi-stage electric push rod 204 to start, so that the multi-stage electric push rod 204 drives the drawing pad 301 to move outside the support rod 201, so that the position of the drawing pad 301 can be adjusted, and then the spatial distance relationship between the basic pattern and the new drawing content can be adjusted according to the drawing requirements during mathematical modeling. When no adjustment is needed, the multi-stage electric push rod 204 is started to extend it. , the drawing pad 301 is fitted with the drawing frame 101, that is, the drawing paper 306 can be fitted with the transparent drawing board 102. After each drawing is completed, the controller 13 is used to control the camera 401 to start the modeling drawing, so as to realize the storage of the drawing. In addition, during the shooting process, the controller 13 is used to control the start of the electric telescopic rod 407, so that the electric telescopic rod 407 can drive the position of the movable rod 403 to adjust the position of the camera 401, so that the captured picture is more complete.

The wiring diagram of the multi-stage electric push rod 204, camera 401, electric telescopic rod 407 and controller 13 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the multi-stage electric push rod 204, camera 401, electric telescopic rod 407 and controller 13 are no longer explained in detail.
