A circular limiting piece 12 is arranged inside the limiting cavity 6. A first spring 13 is sleeved on the surface of the round rod 11. The circular limiting piece 12 is fixedly connected to the surface of the round rod 11. One end of the first spring 13 is fixedly connected to one end of the circular limiting piece 12. The other end of the first spring 13 is fixedly connected to the inner wall of the limiting cavity 6. Two symmetrically arranged threaded holes 15 are opened on the surface of the sliding plate 4 below. A strip cavity 16 is opened on the side wall of the sliding plate 4 below. A strip sliding plate 17 is slidably connected to the inner wall of the strip cavity 16. A plurality of parallel supporting rods 18 are placed in the strip cavity 16. A protective plate 31 is fixedly connected to the side wall of the sliding plate 4 below. A folding device is arranged on the protective plate 31.

[0030] The folding device includes two groups of support arms 19, which are arranged on the two side walls of the protection plate 31. A workbench 21 is arranged above the protection plate 31. Both side walls of the workbench 21 are provided with sliding grooves 22. Both ends of the two groups of support arms 19 are fixedly connected with fixed round rods 20. One end of the left group of support arms 19 is rotatably connected to the side wall of the protection plate 31, and the other end of the left group of support arms 19 is slidably connected to the inner wall of the sliding groove 22. One end of the right group of support arms 19 is slidably connected to the inner wall of the protection plate 31, and the right group of support arms 19 is rotatably connected to the inner wall of the workbench 21. The side wall of the workbench 21 is fixedly connected with a C-shaped plate 23, and the side wall of the workbench 21 is provided with a fan-shaped plate 2 4. The inner wall of the C-shaped plate 23 is fixedly connected with a fixing rod 25, and the surface of the fixing rod 25 is slidably connected with a movable ring 26. The surface of the movable ring 26 is provided with a limiting groove 27 matching the surface of the fan-shaped plate 24. The surface of the C-shaped plate 23 is sleeved with a second spring 28, and the lower end of the second spring 28 is fixedly connected to the upper end of the movable ring 26, and the other end of the second spring 28 is fixedly connected to the inner wall of the C-shaped plate 23. The side wall of the C-shaped plate 23 is rotatably connected with an L-shaped pressure rod 29, and the other end of the L-shaped pressure rod 29 is rotatably connected to the surface of the movable ring 26. First, by setting two groups of support arms 19, and the two groups of support arms 19 are respectively connected to the workbench 21 and the protective plate 31 in different ways, so that the whole device can be realized. Flexible folding and unfolding, this design not only saves space, but also allows the device to be easily stored when not in use, avoiding taking up too much space. Secondly, one end of the left set of support arms 19 is rotatably connected to the side wall of the protection plate 31, and the other end is slidably connected to the inner wall of the sliding groove 22. This design allows the support arms 19 to slide smoothly during folding and unfolding, reducing friction and resistance and increasing the service life of the device. At the same time, one end of the right set of support arms 19 is slidably connected to the inner wall of the protection plate 31, and the other end is rotatably connected to the inner wall of the workbench 21. This symmetrical design makes the device more stable when folded and unfolded, and is not prone to tilting or shaking. In addition, the C-shaped plate 23, the fan ... The combined use of components such as the plate 24, the fixed rod 25, the movable ring 26, the limit groove 27, the second spring 28 and the L-shaped pressure rod 29 provides a convenient locking and unlocking mechanism for the device. When the relative position of the workbench 21 and the protective plate 31 needs to be fixed, the movable ring 26 only needs to be pressed downward by the L-shaped pressure rod 29 to match the limit groove 27 with the surface of the fan-shaped plate 24 to achieve locking. At this time, the second spring 28 is in a compressed state, providing the necessary elastic force for unlocking. When unlocking is required, only the L-shaped pressure rod 29 needs to be gently lifted, and the movable ring 26 will move upward under the elastic force of the second spring 28, thereby disengaging from the locked state of the fan-shaped plate 24. This design is not only easy to operate, but also safe and reliable.

[0031] Furthermore, a mounting plate 30 is fixedly connected to the rear side wall of the display screen 1, and two symmetrically arranged mounting holes 32 are provided on the side wall of the mounting plate 30. The mounting plate 30 fixedly connected to the rear side wall of the display screen 1 and the symmetrically arranged mounting holes 32 on the side wall not only improve the stability and convenience of the installation of the display screen 1, but also enhance its adaptability and flexibility.

[0032] Furthermore, the distance between the two mounting holes 32 is the same as the distance between the two threaded holes 15, the two threaded holes 15 match the support rod 18, the two mounting holes 32 match the support rod 18, and the design in which the two mounting holes 32 and the two threaded holes 15 are the same distance apart and can both match the support rod 18 improves structural stability and parts versatility.

[0033] Furthermore, the diameter of the round rod 11 is smaller than the diameter of the circular limiting hole 14, ensuring that the round rod 11 can be smoothly inserted into the limiting hole without being blocked or stuck due to excessive size, thereby improving the flexibility and efficiency of assembly.

[0034] Furthermore, the support rod 18 is provided with a threaded connection hole, and the other end of the support rod 18 is provided with a thread, so that it is convenient to select and assemble support rods 18 of different heights in different scenarios.

[0035] Furthermore, the side walls of the front sliding plate 4 are painted black, and the rear sliding plate 4 is a base. The side walls of the front sliding plate 4 are painted black, which is convenient for writing on the side walls of the sliding plate 4 with chalk during demonstration. The design of the rear sliding plate 4 as a base has many advantages, which can not only improve the appearance texture and durability of the product, but also ensure the stability and load-bearing capacity of the overall structure.

[0036] Furthermore, one end of the fixed round rod 20 located on the upper left passes through the inner wall of the workbench 21 and extends to the outside. One end of the fixed round rod 20 is fixedly connected to one end of the fan-shaped plate 24. The fan-shaped plate 24 on the fixed round rod 20 is limited by the movable ring 26 to fix the device.

[0037] Working principle: first pull the strip rod 10 to pull out the front sliding plate 4, then pull the strip sliding plate 17 to adjust the number of strip cavities 16 inside the strip sliding plate 17 according to the demonstration height to reach a suitable position, then tighten the lower end thread of the lowest strip cavity 16 into the threaded hole 15, and finally install the upper end of the strip cavity 16 in the mounting hole 32 and adjust it to a suitable position for easy use, and then open the folding device, the folding device adjusts the workbench 21 to a suitable position, and then presses the L-shaped pressure rod 29 so that the L-shaped pressure rod 29 drives the movable ring 26 to limit the fan-shaped plate 24, so that the entire folding device maintains the adjusted height and limits it, and finally the entire device can be folded after use. At this time, the protection plate 31 can not only protect the display screen 1, but also be folded after use for easy carrying.

[0038] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
