Abstract
The utility model discloses a rope body fastener, which comprises at least a rope-inserting body with a frame body. The frame body comprises a connecting part and an elastic part. The rope body fastener further comprises a clamping part which divides the frame body into an entry hole and an exit hole. The clamping part comprises a support rod located between the connecting part and the elastic part of the frame body and fixedly connected with the frame body, and an elastic piece movably connected with the support rod. The elastic piece can move between the connecting part and the elastic part. The free end of a rope band enters the rope body fastener from the entry hole and then comes out from the exit hole after bypassing the clamping part. By pulling the free end of the rope band, the elastic piece is enabled to move towards the direction of the elastic part. Then the exit hole is gradually decreasing and gradually close to a locking position until the rope band is clamped. When the elastic piece moves away from the elastic part, the exit hole is gradually increasing until the rope band is loosened. The rope body fastener provided in the utility model and having the characteristics of simple structure and low manufacturing cost can be widely applied for tightening and loosening rope bodies such as shoestrings, etc.
