The fastener is made of carbon steel hot-dip galvanized material and is mainly fixed on the 9 × 9.5cm edge columns at both ends of each row. It is used to tighten the steel wires between rows, with 4-5 wires installed on each edge column. It is pre tightened using a rotating shaft method and fixed with cards to prevent detachment. Tightening the steel wires between rows saves time and effort, and is widely used in the installation of orchard hedgerows.
