While the present construction is elastic and flexible, typically by material (e.g., spring steel), the present construction is designed to allow attachment and securement of the rigid members by means of cords, and to change the overall stiffness by changing the pretension of the cords. When the structure is impacted, the elasticity of the structure can increase the response time of the structure to the impact, so that the impact force to the structure in unit time is reduced, and the damage to the structure and the structure protected by the structure is reduced. The flexibility of the structure can enable external impact to be transmitted to all members of the structure, so that damage caused by concentrated impact force acting on part of the structure is avoided. When the impact force is small, the deformation of all the components of the structure is in the elastic deformation range, the impact force disappears, the original shape can be restored, and the structure does not need to be replaced. When the impact force is large, plastic deformation can occur to the pressure-bearing rope component and the buffer ring which are connected between the bearing U-shaped block and the mounting U-shaped block, and the impact energy can be absorbed to play a role in energy consumption. When external force is larger, plastic deformation can occur to the bearing U-shaped block 9 and the mounting U-shaped block, impact energy is further absorbed, and energy is further consumed.

The examples are not intended to be exhaustive or to limit the application to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the application and the practical application, to thereby enable others skilled in the art to best understand and utilize the application.
