When in use, the upper frame 1 or the lower frame 2 can be furniture components such as a sofa cushion, a seat plate, a supporting leg or a supporting column, and the like, so that a user can freely replace and assemble the furniture components through the connecting structure; the mounting and dismounting are more convenient and simpler, the processing cost is lower, and the logistics transportation and the storage are convenient; the furniture can be provided with buffering elasticity, the amplitude of jolt is reduced, and the soft and comfortable use experience is provided.

The upper mounting seat 3 is connected with an upper limiting column 5; and the lower mounting seat 4 is connected with a lower limiting column 6. The upper limiting column 5 and the lower limiting column 6 are arranged to limit the bending degree of the joint, and when the gap between the spring 8 and the upper limiting column 5 and the lower limiting column 6 is smaller, the smaller the range of the shake is, and the higher the compressibility in the longitudinal direction is; when the gap between the spring 8 and the upper limiting column 5 and the lower limiting column 6 is larger, the shaking and adjusting range is larger, the provided buffering feeling and shaking feeling are stronger, the elasticity feeling is stronger in the using process, and the comfortable feeling is better.

The main structure of the elastic element 7 is a spring 8. The buffer elastic force can be provided for the joint, the pressure on the joint is reduced, the pressure is absorbed and dispersed, and the joint is protected.

An upper groove 11 is formed in the upper frame 1, and an upper clamping column 12 is arranged on the upper mounting seat 3 corresponding to the upper groove 11; a lower groove 21 is formed in the lower frame 2, and a lower clamping column 22 is arranged on the lower mounting seat 4 corresponding to the lower groove 21.
