Each flexible light strip 501 has an array of LED beads 5012 integrated on its surface. A flexible connecting strip 502 is fixedly connected between every two adjacent flexible light strips 501. The flexible connecting strip 502 forms a dividing line between every two flexible light strips 501, making it easier for students to distinguish the K-line entities on each flexible light strip 501. A support plate 9 is provided below the base frame 1. A damping pivot 10 is provided between the support plate 9 and the base frame 1. The base frame 1 and the support plate 9 are rotatably connected through the damping pivot 10. Through the above settings, the orientation of the flexible teaching board 5 can be adjusted, improving the overall flexibility. Storage drawers 15 are slidably inserted into both ends of the base frame 1. Through the above settings, it is convenient for instructors to place tools and materials.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Both protective boxes 6 have a first indicator line 601 on their front sides, and the base frame 1 has a second indicator line 101 on its front side. With the above settings, when the instructor is explaining, students can quickly locate the K-line of the area being explained by the instructor, thus improving their understanding efficiency. The upper surface of the base frame 1 is hinged with two symmetrically arranged protective boxes 6 by self-locking hinges. When the protective boxes 6 are folded, they can cover the winding drum 2 inside, achieving a flexible stirring protection effect inside the winding drum 2. When the protective boxes 6 are perpendicular to the base frame 1, they can provide a carrier for fixing the top of the flexible teaching board 5.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The top of the flexible teaching board 5 is fixedly connected to a limiting post 7. Two abutment rods 701 are slidably inserted into both ends of the limiting post 7. The two abutment rods 701 are respectively engaged with the top of the bottom protective box 6. The limiting post 7 allows the flexible teaching board 5 to be fixed after it is unfolded. The bottom of the support plate 9 is hinged with two adjusting plates 11 via self-locking hinges. Each adjusting plate 11 is slidably fitted with a support leg 12. A foot plate 13 is fixedly connected to the end of each support leg 12 that is close to each other. Each support leg 12 is fixedly connected to its adjacent adjusting plate 11 by bolts. The adjusting plates 11 and support legs 12 allow for height adjustment of the flexible teaching board 5, further improving overall flexibility. The bottom of each adjusting plate 11 is equipped with casters 14, facilitating overall movement and improving user convenience.

[0040] Please see Figure 1 , Figure 2 and Figure 3 One of the protective boxes 6 has a control host 16 on one side. The control host 16 has a built-in communication module, storage module and display driver module. The control host 16 is electrically connected to the flexible light strip 501. Through the communication module built into the control host 16, it can interact with an external mobile device app, which is convenient for importing K-line charts or for teachers to draw them themselves. Through the display driver module, it can control the color and on / off of the LED beads 5012, thereby displaying or quickly drawing K-line entities or lead lengths of different lengths and colors on each flexible light strip, which is convenient for users to teach.

[0041] This embodiment of a foldable teaching stand for financial securities uses a flexible light strip 501 combined with an array of LED beads 5012 to quickly draw and display different candlestick body colors and lengths, intuitively distinguishing between bullish and bearish candlesticks. Combined with the physical boundary line formed by the flexible connecting strip 502, it allows students to quickly identify classic candlestick patterns, avoiding the tedious process of traditional hand-drawing. Furthermore, when the protective box 6 is folded and closed, it completely encloses the rewind tube 2 and the flexible teaching board 5. When not in use, it not only reduces the floor space but also protects the flexible teaching board 5. The adjustable height of the support legs 12 and the damping pivot 10 allow for adjustments to the height and orientation of the flexible teaching board 5, improving overall flexibility and meeting the needs of use in various environments.

[0042] It should be noted that the control host 16 can store classic candlestick pattern data, which can be easily switched by the instructor with one click.

[0043] The working principle of the above embodiment is as follows: Two symmetrical protective boxes 6 are manually unfolded outwards. When the protective boxes 6 are rotated to be perpendicular to the base frame 1, the self-locking hinges automatically lock the angle, forming a stable vertical support structure. The top limiting post 7 of the flexible teaching board 5 is grasped, and the flexible light strip 501 unfolds outwards, overcoming the preload of the spiral spring 4. After the flexible teaching board 5 is fully unfolded, the abutment rods 701 at both ends of the limiting post 7 are pulled away from each other and engage with the top of the protective box 6, completing the locking. The support plate 9 is manually rotated via the damping shaft 10 below the base frame 1, allowing the flexible teaching board 5 to face different directions to meet the teaching needs of different viewing angles. Loosen the fixing bolts between the support leg 12 and the adjusting plate 11, move the support leg 12 up and down along the slide rail of the adjusting plate 11 to the required height, and then tighten the bolts to complete the height fixation, which facilitates the adjustment of the height of the flexible teaching board 5. The first indicator line 601 on the front of the protective box 6 and the second indicator line 101 on the base frame 1 form a rectangular coordinate system, which makes it easy for students to quickly locate their area. By connecting the communication module of the control host 16 to the mobile device APP, it is easy for the instructor to import preset K-line data or draw manually. The display driver module can control the color of the LED beads 5012, thereby distinguishing the two colors of K-lines.
