2. According to the invention, through the circulation of gas in the hollow ring body and the telescopic hose and the elastic recovery capability of the hollow ring body and the telescopic hose, when the cable is not influenced by external force, the cable can be rapidly restored through the flowing action of the gas and the elasticity of an object.
