A steel wire rope connector for well drilling comprises a pull ring (1), a short hinge shaft (2), an outer taper sleeve (3), an inner taper sleeve (4), a lower long hinge shaft (5), a connecting plate(6) and a clamp (7). The steel wire rope connector for well drilling is characterized in that the two ends of a pull ring (1) of the steel wire rope connector for well drilling are hinged to two lughandles (3-1) of an outer taper sleeve (3) through short hinge shafts (2), the outer taper sleeve (3) is connected with an inner taper sleeve (4) through threads, and the inner taper sleeve (4) is connected with a connecting plate (6) and a clamp (7) through long hinge shafts (5). The utility model is suitable for threading steel wire ropes or large hoisting machinery in oil field drilling. The device is simple in structure and low in manufacturing and maintenance cost, particularly, the steel wire rope is clamped by the clamping teeth of the inner taper sleeve and the cone of the outer tapersleeve under threaded conne
