Description

Technical Field

[0001] The present application relates to the field of mechanical technology, and in particular to a towing rope expansion retainer suitable for cables. Background Art

[0002] A tow rope is a device used to protect cables from wear, tear, entanglement and looseness during frequent movement. The end of the tow rope is a mesh that can be stretched axially and then contracted radially. After the mesh is connected to the outer wall of the cable, the more the user pulls the mesh, the more the mesh contracts radially and firmly fixes the cable. However, the tow rope in the prior art is made of steel cable. When fixing it to the end of the cable, it is necessary to push the tow rope hard to keep it in an axially contracted but radially stretched posture, which is very labor-intensive.
