Disc springs, also known as Belleville spring washers, are conical discs that can be used individually or in series or in parallel. They bear static or dynamic loads acting in the axial direction at the upper inner edge and the lower outer edge. After being compressed, they deform until they are flattened, storing energy as a live load.

[0016] 1. The present invention utilizes guide posts to ensure the spring remains vertical and stable during deformation, thereby connecting the upper and lower chassis in series. When external forces act on the long-travel disc spring assembly, each disc spring deforms sequentially, absorbing and storing energy. Because multiple disc springs are connected in series, the deformation of the entire spring assembly can be significantly increased, achieving a long-travel effect. The positioning cylinders provided secure and position the disc springs, preventing them from shifting or tilting during deformation.

[0017] 2. The specially designed anti-slip component can increase the anti-slip performance of the disc spring, so that it can be stably connected and ensured not to slip. BRIEF DESCRIPTION OF THE DRAWINGS
