Patent attributes
A reinforcing bar binding machine capable of reliably performing a wire gripping operation includes a first movable gripping member that is displaced in a direction to contact with and separate from one side of a fixed gripping member and a second movable gripping member that is displaced in a direction to contact with and separate from the other side of the fixed gripping member. A bending portion brings the first movable gripping member and the second movable gripping member into and out of contact with the fixed gripping member. The fixed gripping member includes a shaft that rotatably supports the first movable gripping member and the second movable gripping member. Further, the bending portion includes an opening and closing pin that pushes an opening and closing guide hole provided in the first movable gripping member, and an opening and closing guide hole provided in the second movable gripping member.
