The Chinese patent document with the publication number CN208150773U discloses a steel wire rope fastener with increased load. Its solution includes a steel wire rope and a fastener structure formed by respectively bending back the two ends of the steel wire rope and locking them with aluminum alloy fixing sleeves. The two rope ends respectively bent back at the two ends of the steel wire rope extend to intersect and merge into a lap joint section parallel to the original steel wire rope, and the lap joint is locked in the aluminum alloy fixing sleeve. However, the aluminum alloy fixing sleeve lock used to lock the steel wire rope in the above solution cannot be disassembled, resulting in its non-reusability. And when the size of the fastener structure needs to be adjusted later, the aluminum alloy fixing sleeve lock needs to be cut. This process not only causes the scrapping of the aluminum alloy fixing sleeve lock, but also easily damages the steel wire rope during the cutting process.
