[0002] In the field of photovoltaic brackets, the end anchors of the steel strands of flexible photovoltaic brackets mostly adopt various connection methods such as arc-shaped clip anchors and extrusion anchors. Among them, the connection method of arc-shaped clip anchors is widely used in actual projects. Traditional arc-shaped clip anchors generally include an anchor ring and several arc-shaped clips. When in use, the anchor ring is put on one end of the steel cable, and then several arc-shaped clips are inserted into the gap between the anchor ring and the steel cable.
