[0032] Refer to Figures 1 to 3, an embodiment provided by the utility model: a project cost progress management device, including a chassis 1. The chassis 1 is the foundation of the entire device. It is designed in a disc shape to increase the contact area with the ground and improve the supporting force. A sleeve 2 is fixedly connected to the top of the chassis 1. The inside of the sleeve 2 is hollow and used to accommodate the telescopic structure. A telescopic rod 3 is slidably connected inside the sleeve 2. By lifting and lowering the telescopic rod 3, the height of the entire device is driven to adjust, achieving different height display effects. A fixed block 6 is fixedly connected to the rear side of the sleeve 2. The fixed block 6 is used to support and stabilize the subsequent structure. A connecting rod 7 is rotatably connected inside the fixed block 6. One end of the connecting rod 7 is rotatably connected inside the fixed block 6, and the other end of the connecting rod 7 can move up and down. A pedal 8 is fixedly connected to the rear side of the connecting rod 7. The pedal 8 directly bears the acting force to change the height of the device. Two fixing plates one 9 are fixedly connected to the rear side of the sleeve 2. A rotating plate 10 is rotatably connected to the adjacent sides of the two fixing plates one 9. By rotating the rotating plate 10, one end is lifted, driving part of the mechanism to rise, thereby driving the lifting of the telescopic rod 3 and the display board 4. A connecting plate 11 is rotatably connected inside the rear side of the rotating plate 10. The connecting plate 11 serves as a transmission component to transmit the force of the downward movement of the connecting rod 7 and drive the rotation of the rotating plate 10. A clamping block one 14 is rotatably connected inside the front side of the rotating plate 10. One end of the clamping block one 14 is clamped in the card slot inside the telescopic rod 3. A spring one 12 is fixedly connected inside the rotating plate 10. The front side of the spring one 12 is fixedly connected to a clamping column 13. The spring one 12 is used to generate a thrust on the clamping column 13, pushing the clamping column 13 to generate a pressure on the clamping block one 14 to produce a clamping limit. A pressing rod one 15 is fixedly connected to the top of the clamping block one 14. The pressing rod one 15 can drive the clamping block one 14 to separate from the telescopic rod 3 through rotation, completing the height reduction of the telescopic rod 3. A limiting component is fixedly connected to the right side of the sleeve 2 to limit and fix the lifted structure. A display board 4 is fixedly connected to the top of the telescopic rod 3. A clamping component is arranged on the rear side of the display board 4 to clamp and fix the display drawings.

[0033] Refer to Figure 1 and Figure 5, the clamping assembly includes two rotating shafts 20 and a pull rod 23. The upper and lower ends of the two rotating shafts 20 are respectively rotatably connected to the left and right sides inside the display board 4. By the rotation of the rotating shafts 20, the clamping and separation of the clamping assembly are driven. A receiving groove 19 is provided at the top of the display board 4, and the receiving groove 19 is used to receive the paper documents to be displayed. Two clamps 5 are fixedly connected to the far sides of the two rotating shafts 20. The clamps 5 directly clamp the paper documents on the display board 4. A plurality of connecting rods 21 are respectively rotatably connected to the adjacent sides of the plurality of clamps 5. A second spring 24 is sleeved on the outer part of the pull rod 23. A connecting plate 22 is fixedly connected to the outer part of the pull rod 23. The adjacent ends of the plurality of connecting rods 21 are rotatably connected to the inside of the connecting plate 22. By the rotational connection between the connecting rods 21 and the connecting plate 22, when the connecting plate 22 is driven by the pull rod 23, one end of the connecting rod 21 is also driven to make a relative movement.

[0034] Refer to Figures 1 to 3 , the bottom of the connecting plate 11 is rotatably connected to the top of the connecting rod 7. Through the rotational connection between the connecting plate 11 and the connecting rod 7, the transmission function is realized. By the rotation of one end of the connecting rod 7, the connecting plate 11 is driven to move. The front side of the clamping post 13 is in contact with the rear side of the first clamping block 14. The front side of the first clamping block 14 is engaged with the inside of the telescopic rod 3. By the contact between the clamping post 13 and the first clamping block 14, a squeezing force is generated, so that the first clamping block 14 is engaged with the inside of the clamping groove of the telescopic rod 3.

[0035] Refer to Figure 4 , the limiting assembly includes two second fixing plates 16. The left sides of the two second fixing plates 16 are fixedly connected to the right side of the sleeve 2. The second fixing plates 16 are used to provide a supporting force for the subsequent limiting assembly. A second clamping block 17 is rotatably connected to the adjacent sides of the two second fixing plates 16. The second clamping block 17 is used to limit the telescopic rod 3 after it is raised to prevent it from descending. A second pressing rod 18 is fixedly connected to the right side of the second clamping block 17. The left side of the second clamping block 17 is engaged with the inside of the telescopic rod 3. By adjusting the rotation of the second pressing rod 18, the engagement and separation between the second clamping block 17 and the telescopic rod 3 are realized.

[0036] Refer to Figure 5 , one end of the second spring 24 is fixedly connected to the rear side of the display board 4, and the other end of the second spring 24 is fixedly connected to the front side of the connecting plate 22. Through the fixed connection of the second spring 24, a reaction force is provided for the movement reset of the connecting plate 22 for clamping.

[0037] Working principle: First, place the device at the position where it needs to be displayed. Pull the pull rod 23 backward to drive the connecting plate 22 to move backward. At the same time, the movement of the connecting plate 22 pulls the second spring 24 to elongate and deform. The movement of the connecting plate 22 drives one end of multiple connecting rods 21 to rotate, thereby driving multiple clamps 5 to rotate around the rotating shaft 20, realizing the separation of multiple clamps 5 from the front side of the display board 4. Then take out the paper content of the project cost from the inside of the accommodation groove 19 and place it between the clamp 5 and the display board 4. Release the pull rod 23, and the connecting plate 22 is pulled back to its original position by the reaction force of the second spring 24, thereby driving multiple clamps 5 to rotate back to their original positions and clamping the paper folder on the front side of the display board 4. Through the clamping mechanism that is easy to operate, it is convenient to clamp and replace the paper project cost content, and more intuitively display the progress management of the project cost.

[0038] Secondly, the staff steps on the pedal 8 to drive one end of the connecting rod 7 to rotate downward, thereby driving the connecting plate 11 to move downward, and then driving the rotating plate 10 to rotate. At the same time, when the rotating plate 10 rotates, the first clamping block 14 rotating inside the front side of the rotating plate 10 is driven to move upward. The first clamping block 14 is clamped inside the telescopic rod 3, and the movement of the first clamping block 14 drives the telescopic rod 3 to move upward. At the same time, due to the upward movement of the telescopic rod 3, the second clamping block 17 clamped on the right side of the telescopic rod 3 will be clamped at the corresponding height to prevent the telescopic rod 3 from falling. Through the lifting device and the limiting mechanism, the height of the display board 4 can be adjusted as needed, so that the content can be displayed at the best height in different viewing scenarios or usage scenarios, providing a better visual experience and readability.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
