In the overhead power line, the U-shaped hanging ring is often used to connect the insulator string or the steel strand to the pole tower. When connecting, the pin or bolt is inserted into the eyelet to fix it. The eyelet in the U-shaped hanging ring is usually completed by a U-shaped hanging ring opening device. When the existing U-shaped hanging ring opening device is used, when a U-shaped hanging ring is drilled and touched, the U-shaped hanging ring needs to be removed from the clamping part, and a new U-shaped hanging ring to be drilled is placed in the clamping part, and the U-shaped hanging ring is fixed before drilling.
