[0029] Specifically: a pressure groove 12 is provided on the lower shock absorber shaft 2, a first limiting post 21 is fixedly connected in the pressure groove 12, a symmetrical second limiting post 22 is fixedly connected to the side of the first limiting post 21, and a second spring 15 is movably connected on the first limiting post 21 and the second limiting post 22 to enhance the buffering capacity of the shock absorber.

[0030] Specifically: A pressure column 17 is fixedly connected to the lower end of the upper shock absorber shaft 1. The pressure column 17 is movably connected to the pressure groove 12.

[0033] Working principle:

[0034] The lower end of the upper shock absorber shaft 1 is movably connected to the lower shock absorber shaft 2, allowing for flexible handling of vibrations from different directions. A first spring 5, fitted onto both shafts, absorbs vibration energy and provides initial cushioning through its own expansion and contraction. A rotating hole 9 on the upper shock absorber shaft 1 cooperates with a fixed bushing 8. The fixed bushing 8, movably connected within the rotating hole 9, ensures stable rotation of the upper shock absorber shaft 1 during vibration, reducing the adverse effects of misalignment and ensuring smooth shock absorption. A movable fixed plate 6 is fitted into the mounting groove 16 at the lower end of the lower shock absorber shaft 2. Its multiple threaded holes 7 facilitate secure connection with other vehicle components, ensuring the entire shock absorber is firmly installed on the vehicle and effectively transmits and disperses vibrations. The first limiting plate 3 and the lower first limiting sleeve 10, along with the second limiting plate 4 and the upper second limiting sleeve 11, work together on the first spring 5. When the first spring 5 expands and contracts, the limiting sleeve precisely controls its expansion and contraction range, preventing excessive stretching or compression of the spring and ensuring stable and reliable shock absorption. The pressure groove 12 and its internal structure on the lower shock absorber shaft 2 are key components of the shock absorption system. A first limiting post 21 is fixed inside the pressure groove 12, and a symmetrical second limiting post 22 is connected to its side. A second spring 15 is fitted onto both. A pressure post 17 at the lower end of the upper damping shaft 1 is movably connected to the pressure groove 12. A first limiting post 19 and a second limiting post 20 on the pressure post 17 engage with the first limiting post 21 and the second limiting post 22, respectively. When vibration is significant, the pressure post 17 moves within the pressure groove 12, and the second spring 15 further absorbs and disperses the vibration energy, enhancing the buffering capacity. A ball bearing 14 inside a sleeve 13 is mounted on the side of the pressure groove 12 and movably connected to the pressure post 17, converting sliding friction into rolling friction. This greatly reduces the friction between the pressure post 17 and the pressure groove 12, reducing component wear. A soft pad 18 connecting the upper end of the lower damping shaft 2 to the lower end of the upper damping shaft 1 also effectively reduces the hard impact between them.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
