A connecting spring 12 is fixed between one end of the mounting plate 11 and the inner wall of the fixing groove 10, and one end of the mounting plate 11 is outside the opening of the fixing groove 10. The bottom surface of one end of the mounting plate 11 is fitted and connected with the surface of the mounting ring 7, and the end surface of the mounting plate 11 facing the outside of the fixing groove 10 is inclined. The surface width of the mounting plate 11 is not greater than the inner wall depth of the fixing groove 10, which is convenient for limiting the rotation of the abutment joint 4 toward the wire rope, so that the wire rope is not easy to deviate left and right, which is convenient for the operator to quickly abut the abutment joint 4 with the wire rope, so as to improve the efficiency and effect of the inspection and detection of the wire rope tension, and has good practicality.
