The utility model passes the wire rope through the perforation, and then places the wire rope knot formed by tying the two ends of the wire rope into the fixing ring. After the fixing ring is mounted on the upper end of the fixing seat, the fixing bolts are passed through the fixing ring and fixedly connected to its screw holes, thereby achieving a fixed connection between the fixing ring and the fixing seat. The fixation can improve the accuracy of the data during the wire rope bending stiffness test.

[0004] However, when using this utility model, the steel wire rope is first passed through the through hole, and then the steel wire rope knot formed by tying the two ends of the steel wire rope is placed in the fixing ring.

The operation is cumbersome, increases the labor intensity of the workers, and has a poor use effect. Utility Model Content
