Steel wire clamping device and application thereof in heat treatment production of steel wire

The invention discloses a steel wire clamping device. The front end of the bearing rod is provided with a jaw and the rear end is provided with a handle. A tension spring is provided in the bearing rod. Both ends of the tension spring are respectively connected with the jaw and the handle. A locking buckle is provided on the jaw. In the heat treatment production of steel wire, when the steel wireis running, the handle of the steel wire clamping device can be held with hands at the front roller of the heating section, the jaw is opened to align the tail of the steel wire of the running head. The jaw can hold the steel wire firmly with firm holding of the handle while holding the steel wire. The jaw clamps the tail of the running steel wire and raises the steel wire to prevent the running steel wire from contacting other steel wires which causes sparks to damage the steel wire.
