[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road. Hollow piston rods are required in shock absorbers. However, the existing hollow piston rods are simply hollowed out and no reinforcement structure is set to improve the structural strength of the piston rod. This makes the piston rod lighter, but also reduces the structural strength of the piston rod, making it inconvenient to use.

[0003] For example, a hollow piston rod of a shock absorber with publication number CN219549466U includes a main rod, and connecting rods are provided at the top and bottom ends of the main rod. The ends of the two connecting rods close to each other are fixedly connected to extended threaded rods, and the two connecting rods are threadedly connected to the main rod through the extended threaded rods. The outer surface of each extended threaded rod is provided with a first gasket, and the outer surface of each connecting rod is fixedly connected to a baffle. This technical solution also has the technical problems mentioned above. Utility Model Content
