Wire saw joint

The utility model provides a wire saw joint, which comprises a cavity used for the insertion of a wire rope. The wire saw joint comprises an inner layer arranged at the inner side of the joint and an outer layer arranged at the outer side of the joint. The cavity is positioned in the inner layer. The hardness of the outer layer is greater than the hardness of the inner layer. The outer layer is made of steel material and the inner layer is made of copper material, or the outer layer is made of steel material and the inner layer is made of rubber material. According to the utility model, steel and copper or rubber materials are respectively adopted for manufacturing the inner and outer layers of the wire saw joint. During the cutting process of the wire saw, the outer layer made of steel material is wear resistant, so that the wire rope is protected to a certain extent. The inner layer made of copper or rubber material is better in toughness, so that the local stress concentration is avoided. Therefore, the se
