When the hinge shaft is working, external force acts on the rotating shaft one 3 and the rotating shaft two 4, so that they rotate around the shaft core 1. At this time, the limiting disc 5 plays an important role, which is fixedly connected to the upper and lower ends of the shaft core 1, and can limit the rotation range of the rotating shaft one 3 to prevent it from being damaged by excessive rotation. The buffer pad 6 fixedly connected to the limiting disc 5 can play a buffering role when the rotating shaft one 3 moves up and down, reducing the impact force and prolonging the service life. At the same time, the spring 8 will deform, and through its elastic force, it can buffer and adjust the force generated when the rotating shaft one 3 rotates, further improving the stability and durability of the hinge shaft, protecting the rotating shaft one 3 and the entire hinge shaft structure, achieving self-buffering protection, thereby prolonging the service life.

The screw 205 is sequentially penetrated through the fixed block 203 and is screw-connected to the inner wall of the threaded groove 202 on the front side of the connecting block 201. By tightening the screw 205, the fixed block 203 and the connecting block 201 are tightly connected. This connection method not only ensures the stability of the connection, but also facilitates disassembly and replacement. The connecting plate 206 can be connected with other components that need to be connected, so as to realize the expansion connection of the long-life hinge shaft and meet different use requirements.
