The strands of the steel wire rope are scattered and inserted into the spiral grooves respectively. The middle of the vertebral body is also provided with a through hole for placing a steel wire rope core. The tail end of the steel wire rope is pulled, the steel wire rope inserted into the rope strand drives the conical cylinder to move downwards, and the rope strand of the steel wire rope is firmly clamped due to the extrusion effect of the rope sleeve shell and the conical cylinder, so that the connection of the steel wire rope and the pear-shaped rope sleeve is completed.
