Two sides of the rope holding part are provided with guide wings which are fixedly connected with the rope holding part into a whole; anti-skid teeth are distributed on the surfaces of the main jaw and the auxiliary jaw; an anti-rotation plane is arranged on the bushing, and a stop block matched with the anti-rotation plane is fixed at the left end of the mounting sleeve.

Compared with the prior art, the utility model discloses adopted above-mentioned technical scheme on traditional structure's basis, consequently had following advantage:

1) the main plier body sliding groove adopts an inverted convex structure, and the auxiliary plier body adopts a T-shaped structure matched with the sliding groove, so that the guiding precision of the auxiliary plier body in the sliding groove can be effectively improved, and the defect that the main plier mouth and the auxiliary plier mouth are easy to misplace is overcome.

2) The main plier body is provided with a plane for preventing rotation, and the body is provided with a stop block, so that the main plier body can not rotate even if the main plier body is slightly loosened, and the defect that the main plier mouth and the auxiliary plier mouth are easy to stagger is overcome.

3) The anti-skid teeth which are vertically distributed are arranged on the arc surfaces of the main jaw and the auxiliary jaw, so that the friction force between the anti-skid teeth and the cable is increased, and the use requirement of a large-gradient road section can be completely met.

4) The two sides of the rope holding part are provided with the guide wings which are fixedly connected with the rope holding part into a whole, so that the rope clip is convenient and quick to pick up or hang.
