A U-shaped ring with a through hole is fitted onto the adjustment pin, which has an anti-loosening mechanism and a nut is threaded onto one end. This utility model, through the cooperation of the positioning post, the limiting plate, and the T-shaped groove and arc groove, allows for flexible rotation of the mounting head relative to the fixing head, meeting the needs of multi-angle rope connections. It is suitable for various scenarios such as outdoor operations, industrial traction, and daily use, exhibiting strong practicality and high promotional value.
