The fixing rings 15 provide support for the threaded posts 21 and allow them to rotate freely, facilitating adjustment during operation. The threaded posts 21 control the fixing and loosening of the engaging assembly through rotation, providing a necessary adjustment mechanism for the precise positioning of the fixing block 13 and ensuring smooth operation of the entire system. A connecting shell 16 is fixedly connected to one side of each fixing ring 15. The connecting shell 16, through its connection with the fixing ring 15, ensures structural stability between the fixing ring 15 and the threaded post 21, while providing stable support for subsequent engaging. Each connecting shell 16 has a fixing shell 17 on its outer wall. The fixing shell 17 serves to protect and support the connecting shell 16, preventing damage from external forces. Simultaneously, the design of the fixing shell 17 ensures the reliability and stability of the engaging assembly, making the connection process smoother. The outer wall of the fixing shell 17 is fixedly connected to the inside of the connecting block 14, ensuring the structural integrity of the engaging assembly. Through this tight fixation, the connecting block 14 can better support other components of the engaging assembly, enhancing the stability and durability of the assembly. Each threaded post 21 has a handle 22 fixedly connected to one end, allowing the user to easily operate the threaded post 21. By operating the handle 22, the user can easily adjust the rotation of the threaded post 21, thereby adjusting the position of the entire engaging assembly, providing a more convenient user experience. The other end of the threaded post 21 is fixedly connected to a connecting post 20, which transmits the rotational motion of the threaded post 21 to the locking block 19. Each connecting post 20 is fixedly connected to one end with a locking block 19. The locking block 19, through its connection to the connecting post 20, can move during adjustment, thus ensuring the stability of the entire locking component. Each locking block 19 has multiple locking balls 18 on its outer wall. The locking balls 18 provide precise locking functionality, ensuring that the locking block 19 can be firmly fixed in a predetermined position. The locking balls 18 are slidably connected inside the connecting shell 16, engaging with the inner wall of the fixing shell 17, thereby achieving precise locking of the locking component. When the locking balls 18 engage with the inner wall of the fixing shell 17, the locking block 19 is fixed in the correct position, ensuring that the entire locking component is stable and reliable.

[0037] Specifically, during the device locking process, the connecting block 14 on one side of the display screen 1 is moved to the outer wall of the fixing block 13. The function of the connecting block 14 is to provide a stable connection point, allowing the display screen 1 to be firmly connected to the fixing block 13. By precisely moving the connecting block 14 to the outer wall of the fixing block 13, the accuracy and stability of the connection process are ensured, providing a solid foundation for fixing the display screen 1. Then, the fixing shell 17 is inserted into the outer wall of the connecting shell 16. The insertion design of the fixing shell 17 and the connecting shell 16 ensures a tight fit between them. When the fixing shell 17 is inserted into the outer wall of the connecting shell 16, the precise structural design ensures the stability of the connection, preventing the display screen 1 from loosening or falling off during subsequent use, thus improving the overall safety and stability of the device. Subsequently, the rotating handle 22 pushes the threaded post 21 into the connecting shell 16. The design of the rotating handle 22 allows the user to operate conveniently, controlling the position of the display screen 1 by pushing the threaded post 21, making it more tightly connected to the fixing block 13 and the connecting block 14. The threaded post 21 achieves precise displacement through rotation, pushing other components inside the connecting shell 16 to ensure the display screen 1 is firmly fixed. As the threaded post 21 moves, it pushes the locking block 19 to the outer wall of the locking ball 18 via the connecting post 20. The connecting post 20 transmits the pushing force of the threaded post 21 to the locking block 19, allowing the locking block 19 to smoothly push the locking ball 18. The locking ball 18 is designed to slide in the opposite direction inside the connecting shell 16, engaging with the inner wall of the fixing shell 17. During its movement, the locking ball 18, through contact with the inner wall of the fixing shell 17, ensures precise engagement of the display screen 1, preventing any loosening or displacement, until the locking ball 18 and the inner wall of the fixing shell 17 are fully engaged, achieving the locking and fixing effect of the display screen 1. After the locking ball 18 and the inner wall of the fixing shell 17 are engaged, the display screen 1 is firmly fixed in the designated position, ensuring its stability during use. Through this engagement process, the display screen 1 not only avoids displacement due to external forces but also maintains its long-term stable display effect.

[0038] Reference Figures 1-4The adjustment assembly includes a lifting column 5, located on the outer wall of the connecting block 14. The lifting column 5 serves as the core support component of the entire adjustment assembly, ensuring smooth height adjustment and stability of the equipment when needed. The stability of the lifting column 5 directly affects the height adjustment effect and stability during use. A fixing block 13 is fixedly connected to the top of the lifting column 5 at its bottom. The fixing block 13 connects the lifting column 5 to other components, ensuring that the lifting column 5 does not shift during adjustment. It provides stable support for the lifting column 5, ensuring smooth adjustment operations. A fixing tube 4 is slidably connected to the outer wall of the lifting column 5. The fixing tube 4 provides external guidance for the lifting column 5, ensuring smooth up-and-down sliding without jamming. The connection between the fixing tube 4 and the lifting column 5 provides a stable structure, ensuring the lifting column 5 remains stable during adjustment. A sleeve 6 is fixedly connected to the outer wall of the fixing tube 4. The sleeve 6 further supports the fixing tube 4 and ensures smooth rotation of the internal rotating components. The sleeve 6 provides space and support for the rotating bar 9, allowing it to rotate freely and drive the movement of other components. The rotating bar 9 is rotatably connected inside the sleeve 6, and a pressing plate 10 is fixedly connected to the outer wall of the rotating bar 9. The rotating bar 9 transmits the rotational motion to the pressing plate 10, whose design allows the user to adjust the height of the device by rotating it. The rotation of the pressing plate 10 facilitates the adjustment process. A locking post 12 is fixedly connected to one side of the pressing plate 10, engaging with the inside of the lifting column 5. The locking post 12 ensures that the lifting column 5 is securely locked at the appropriate height during adjustment, preventing unnecessary changes in height. A spring 11 is provided on the outer wall of the sleeve 6, providing elastic support to help the pressing plate 10 return to its original position during adjustment. Spring 11, through compression and rebound, ensures that the locking pin 12 can quickly engage inside the lifting pin 5, thereby fixing the position of the lifting pin 5. One end of spring 11 is fixedly connected to the outer wall of the pressing plate 10, and the other end is fixedly connected to the inside of the sleeve 6. The connection of the two ends of spring 11 ensures a tight connection between the pressing plate 10 and the sleeve 6. At the same time, the elasticity of spring 11 makes the adjustment process smoother, preventing jamming or resistance caused by improper operation. A support column 2 is fixedly connected to the outer wall of the fixing tube 4. The function of the support column 2 is to provide additional support force for the fixing tube 4, preventing the fixing tube 4 from bending or deforming during the adjustment process, and ensuring the stability and durability of the overall adjustment system. Gears 8 are rotatably connected to both sides inside the fixing tube 4. The function of gears 8 is to provide precise control of the lifting pin 5 by meshing with the rack 7.The meshing of gear 8 and rack 7 ensures that the lifting column 5 can move smoothly up and down without displacement or uneven lifting. A rack 7 is fixedly connected to the bottom of the lifting column 5, and the rack 7 meshes with the gear 8. The rack 7 works in conjunction with the gear 8 to provide precise control for the up and down movement of the lifting column 5, making the lifting process smoother and maintaining stability at the desired height. A chassis 3 is fixedly connected to the bottom of the support column 2. The chassis 3 provides support for the entire adjustment assembly, ensuring that the entire device stands stably and preventing tilting or instability during adjustment. The design of the chassis 3 ensures that the entire system remains balanced during operation, enhancing the stability and service life of the adjustment assembly.

[0039] Specifically, during the height adjustment of the display screen 1, the pressing plate 10 is first pressed, causing it to rotate around the rotating bar 9. The rotation of the pressing plate 10 pushes the locking pin 12 out of the lifting column 5. The removal of the locking pin 12 allows the lifting column 5 to be freely adjusted vertically, adjusting the height of the display screen 1 to suit different usage needs or viewing angles, providing a better user experience. During this process, the rotation of the pressing plate 10 not only pushes the locking pin 12 but also compresses the spring 11. The spring 11 stores energy through compression, providing support for subsequent height fixing. Next, the lifting column 5 moves up and down on the inner wall of the sleeve 6. The smooth up-and-down movement of the lifting column 5 is guided by the sleeve 6, ensuring stability throughout the adjustment process. Simultaneously, the movement of the lifting column 5 causes the rack 7 to move smoothly on the outer wall of the gear 8. The meshing between the rack 7 and the gear 8 provides support for the lifting column 5, preventing instability caused by gravity or external forces during the lifting process. The precise engagement of rack 7 and gear 8 ensures a smoother lifting process and effectively distributes the load on the lifting column 5, enhancing the stability and durability of the entire system. Once the lifting column 5 has reached the desired height, the pressure on the pressing plate 10 is released. At this point, the rebound force of the spring 11 pushes the locking pin 12 into the interior of the lifting column 5, ensuring that the lifting column 5 is fixed in the required position. The rebound force of the spring 11 effectively pushes the locking pin 12, ensuring it is firmly fixed inside the lifting column 5, thereby achieving precise locking of the height position of the display screen 1. This process not only prevents the lifting column 5 from shifting during use but also improves the convenience and stability of equipment adjustments.

[0040] Working principle: During the device locking and fixing process, the connecting block 14 on one side of the display screen 1 is moved to the outer wall of the fixing block 13, and the fixing shell 17 is inserted into the outer wall of the connecting shell 16. Then, the handle 22 is rotated to push the threaded post 21 into the connecting shell 16. As the threaded post 21 moves, it pushes the locking block 19 to the outer wall of the locking ball 18 through the connecting post 20, causing the locking ball 18 to slide in the opposite direction inside the connecting shell 16 until the locking ball 18 and the inner wall of the fixing shell 17 are locked together, achieving the locking and fixing effect of the display screen 1. During the height adjustment of the display screen 1, the pressing plate 10 is pressed to... The pressing plate 10 rotates around the rotating bar 9, pushing the locking pin 12 out of the lifting column 5 and compressing the spring 11. The lifting column 5 then moves up and down on the inner wall of the sleeve 6. Simultaneously, the rack 7 moves on the outer wall of the gear 8, providing support for the lifting column 5 through the meshing between the rack 7 and the gear 8. Once the lifting column 5 reaches the appropriate height, the pressing force on the pressing plate 10 is released, and the rebound force of the spring 11 pushes the locking pin 12 into the lifting column 5, thus fixing the position of the lifting column 5 and enhancing the applicability of the equipment.
