After completing the adjustment of the movable plate 7, the user can choose to display a bar graph or a line graph. When displaying a bar graph, the user can pull the magnetic plate 54 to move upward, so that the magnetic plate 54 is adsorbed on the lower side of the movable plate 7. The foldable elastic band 53 is stretched out at this time. The height of the foldable elastic band 53 is the height of the bar chart data display. When displaying a broken line chart, the user does not need to pull the magnetic plate 54 upward. The user can pull the display line 32. When the display line 32 is pulled, the winding roller 33 is driven to rotate so that the display line 32 is released and lengthened. At this time, the torsion spring 31 is compressed, and the display line 32 is wound around the circumferential end of each winding shaft 72, so that the winding roller 33 forms a node at the winding shaft 72 to form a broken line chart; A wire outlet 41 is penetrated through the side end portion of the side rod 4, and two wire pressing plates 42 are provided on the inner side wall of the wire outlet 41.

The toothed belt 23 and each driven gear 6 are meshed. In actual analysis, there are dynamic changes in data. For example, there is a situation where the data is synchronously increased or decreased. At this time, it is necessary to synchronously adjust the height of each movable plate 7. The user can turn the handle 22. The rotation of the handle 22 will drive the rotation of the shaft 2. The rotation of the shaft 2 will drive the transmission gear 21 to rotate. The rotation of the transmission gear 21 will drive the toothed belt 23 to rotate through the internal teeth 24. The forward or reverse rotation of the toothed belt 23 will simultaneously drive multiple driven gears 6 to rotate, thereby synchronously realizing the forward or reverse rotation of each lead screw 65, and then synchronously driving each movable plate 7 to move upward or downward; A thread groove 71 is formed through the upper end of each movable plate 7, and each screw rod 65 is threadedly installed on the inner wall of the thread groove 71. When using the device, the user can adjust the height of each movable plate 7 so that each movable plate 7 can be adjusted to a height suitable for data display. When adjusting the height of each movable plate 7, the user can pull the pull rod 61 downward, and the movement of the pull rod 61 drives the driven gear 6 to move downward. When the driven gear 6 moves downward and no longer meshes with the toothed belt 23, the user can rotate the pull rod. 61 drives the driven gear 6 to rotate, and the rotation of the driven gear 6 drives the fixed ring 66 to rotate through the third telescopic rod 63, and the rotation of the fixed ring 66 drives the screw rod 65 to rotate, and the forward or reverse rotation of the screw rod 65 will drive the movable plate 7 to move upward or downward. After adjusting the movable plate 7 to a suitable height, the user can stop rotating the pull rod 61 and release the pull rod 61. At this time, the second spring 62 will pull the driven gear 6 to move upward and reset.

The second arrow 73 is set on the side end of the winding shaft 72, and the first arrow 55 is set on the side end of the magnetic plate 54. When displaying the bar chart and the line chart, the setting of the first arrow 55 and the second arrow 73 can cooperate with the scale 13 to realize the intuitive indication and display of the data in the analysis, and at the same time ensure the accuracy of the data indication of the movable plate 7 after adjustment. The side end board surface of the display board 1 of the device is a writable board surface, which is convenient for users to use for data explanation in data analysis, and is more convenient for data analysis to realize the combination of data and graphs.

[0019] Working principle: The first step is to design data processing and analysis in data analysis. Therefore, the user needs to draw a bar graph or a line graph on a blackboard or a whiteboard to more intuitively display some data analysis data. In this way, the user can use the device to display bar graphs and line graphs. By adjusting the height of each foldable elastic band 53, as shown in the attached figure, Figure 1 As shown, the display of the bar graph is realized, and the display line 32 is pulled and wound around each winding shaft 72 to realize the display of the line graph. The bar graph and the line graph can also be displayed at the same time to realize the combined display of the bar graph and the line graph; In the second step, when using the present device, the user can adjust the height of each movable plate 7 so that each movable plate 7 can be adjusted to a height suitable for the data display. When adjusting the height of each movable plate 7, the user can pull the pull rod 61 downward, and the movement of the pull rod 61 drives the driven gear 6 to move downward. When the driven gear 6 moves downward and no longer meshes with the toothed belt 23, the user can rotate the pull rod 61 to drive the driven gear 6 to rotate. The rotation of the driven gear 6 drives the fixed ring 66 to rotate through the third telescopic rod 63. The rotation of the fixed ring 66 drives the screw rod 65 to rotate. The forward or reverse rotation of the screw rod 65 will drive the movable plate 7 to move upward or downward. After adjusting the movable plate 7 to a suitable height, the user can stop rotating the pull rod 61 and release the pull rod 61. When the second spring 62 pulls the driven gear 6 to move upward and reset, the driven gear 6 will mesh with the toothed belt 23 again after reset to adjust the height of a single movable plate 7. In actual data analysis, the data has dynamic changes. For example, the data rises or falls synchronously. At this time, it is necessary to adjust the height of each movable plate 7 synchronously. The user can turn the handle 22. The rotation of the handle 22 will drive the shaft 2 to rotate. The rotation of the shaft 2 will drive the transmission gear 21 to rotate. The rotation of the transmission gear 21 will drive the toothed belt 23 to rotate through the internal teeth 24. The forward or reverse rotation of the toothed belt 23 will simultaneously drive multiple driven gears 6 to rotate, thereby synchronously realizing the forward or reverse rotation of each lead screw 65, and then synchronously driving each movable plate 7 to move upward or downward. The device is provided with a driven gear 6, a screw rod 65 and a movable plate 7 to cooperate with each other. When displaying data during data analysis, the height of the movable plate 7 in the device can be adjusted to realize the display of data changes. In the existing data analysis, it often takes a lot of time for users to draw complex bar charts and line charts, and when the drawing needs to be replaced according to data changes, it is also necessary to erase the drawing, resulting in low efficiency of data analysis. The device can quickly adjust the height of the movable plate 7, and the adjustment is convenient. It can be realized by rotating the driven gear 6, saving drawing time and facilitating efficient analysis by users. The device is provided with a toothed belt 23, an inner tooth 24, a rotating shaft 2 and a transmission gear 21, so that when the data changes synchronously in the data analysis, the user does not need to adjust the data one by one. By turning the handle 22 to drive the rotating shaft 2 to rotate, the toothed belt 23 and the inner tooth 24 can simultaneously drive each driven gear 6 to rotate, so that each movable plate 7 can be synchronously adjusted, so that the display of data changes is more intuitive, and the movable plates 7 can be adjusted one by one while being synchronously adjusted, so that the device is more adaptable in data analysis and the data analysis display is clearer; The third step is that after completing the adjustment of the movable plate 7, the user can choose to display a bar graph or a broken line graph. When displaying a bar graph, the user can pull the magnetic plate 54 upward so that the magnetic plate 54 is adsorbed on the lower end of the movable plate 7. At this time, the foldable elastic band 53 is extended. At this time, the height of the foldable elastic band 53 is the height of the bar graph data display. When displaying a broken line graph, the user does not need to pull the magnetic plate 54 upward. The user can pull the display line 32. When the display line 32 is pulled, the winding roller 33 is driven to rotate so that the display line 32 is released and lengthened. At this time, the torsion spring 31 is compressed, and the display line 32 is wound around the circumferential end of each winding shaft 72, so that the winding roller 33 forms a node at the winding shaft 72 to form a broken line graph. The device is provided with a foldable elastic band 53 and a display line 32 to cooperate with each other, so that the device can realize the combined display of a bar graph and a line graph, and can display a line graph and a bar graph separately, or can display a line graph and a bar graph at the same time. In data analysis, data can be displayed more conveniently and efficiently, and users can flexibly adjust the analysis method according to the actual situation in the classroom; The device is provided with a storage box 52 and a winding roller 33 to cooperate with each other. When the device is not in use, the foldable elastic band 53 and the display line 32 can be stored in the storage box 52 and the winding roller 33 respectively, which can effectively avoid the possibility of the foldable elastic band 53 and the display line 32 being contaminated or worn, and ensure the service life of the foldable elastic band 53 and the display line 32. The device can be repeatedly used for display in data analysis, and the foldable elastic band 53 and the display line 32 can be stored while being protected, so as to facilitate the efficient use of teaching aids; In the fourth step, a second arrow 73 is set at the side end of the winding shaft 72, and a first arrow 55 is set at the side end of the magnetic plate 54. When displaying the bar chart and the line chart, the setting of the first arrow 55 and the second arrow 73 can cooperate with the scale 13 to realize the intuitive indication and display of the data, and at the same time ensure the accuracy of the data indication of the movable plate 7 after adjustment. The side end board surface of the display board 1 of this device is a writable board surface, which is convenient for users to explain the data and is more convenient for data analysis, realizing an analysis method combining data and graphs.
