Automatic wire tying tool for binding reinforcing bars on construction sites. Made from high quality steel, it is designed for easy operation and helps improve work efficiency. Key benefits - Safe and practical: This tool pulls the reinforcing bar to securely and easily join bars. It features automatic recoil and reloading, saving time and reducing hand fatigue. - Time saving and ergonomic: Semi-automatic operation reduces repetitive movements and minimizes strain on hands and wrists. How it works - Semi-automatic operation: An internal thread backlash structure inside the hook automatically retracts the end wire as the handle is pulled, eliminating the need for manual drawing. Applications and use scenarios - On construction sites when binding reinforcing bars for foundations, slabs, or rebar cages. - When assembling reinforced concrete columns or walls, enabling quick and secure wire ties. - In formwork setups to secure tying wires between braces before pouring concrete. Key attributes - Function: binds reinforcing bars using tying wire - Material: high quality steel - Performance: automatic recoil and reloading; semi-automatic grip operation - Design: internal thread backlash structure inside the hook to automatically return the end wire - Compatibility: designed for breaking and tying standard reinforcement wire in typical rebar work
