Fixing device

The invention relates to the technical field of cable fixing, and provides a fixing device which comprises a fixing piece, an annular piece and at least two dampers. The fixing piece is used for being connected with the bending reinforcing piece, the annular piece is arranged outside the fixing piece in a surrounding mode, one end of each damper is connected with the fixing piece, the other end of each damper is connected with the annular piece, and the at least two dampers are arranged between the fixing piece and the annular piece in the circumferential direction at intervals. Based on the arrangement of the annular piece and the dampers outside the fixing piece, linkage can be formed between the at least two dampers and the damping effect of the dampers can offset part of bending moment, so that the load borne by the bending reinforcer is reduced, the risk of fatigue damage of the bending reinforcer in the long-term service process is reduced, and the service life of the bending reinforcer is prolonged.
