The center seat can drive the wire feeding column to rotate relative to the fixed plate; thereby realizing movement in the forward and backward directions and movement in the rotating and circling directions. As for the synchronous rotation, it is to facilitate the continuous cooperation between the subsequent L-shaped hook claw and the swing seat.(3) An L-shaped hook claw extending forward is provided through the edge of the rotating hook plate, and the front end of the L-shaped hook claw extends toward the outside of the rotating hook plate. The edge of the swing fixed seat is rotatably connected to a swing seat extending forward. The swing seat is in a U-shape with an opening facing backward and gradually narrowing. The first side arm of the swing seat is rotatably connected to the edge of the swing fixed seat, and the second side arm of the swing seat is located in front of the edge of the circular push rod seat. The edge of the circular push rod seat can push the second side arm of the swing seat forward so that the swing seat can rotate toward the direction close to the wire feeding column; therefore, when the circular push rod seat moves forward, it will resist the second side arm of the swing seat, thereby pushing the first side arm of the swing seat and the edge of the swing fixed seat to rotate, so that the swing seat can rotate toward the direction close to the wire feeding column. (4) A swing seat retreat hook pin is provided on the second side arm of the swing seat, and the swing seat retreat hook pin extends into the angle of the L-shaped hook claw.

(5) A tool assembly extending to the front of the wire feeding column is provided at the front end of the swing seat, and the swing seat can drive the tool assembly to reciprocate, so that the tool assembly can bend the steel wire conveyed forward by the wire feeding column; because the swing seat can rotate and circle together with the swing fixed seat, and can reciprocate back and forth at the same time, the tool assembly can realize all-round rotation and circle, so that the steel wire conveyed forward by the wire feeding column can be bent from all directions. (6) When the L-shaped hook claw contacts the swing seat retreat hook pin backward, there is a gap between the second side arm of the swing seat and the edge of the circular push rod seat; thus, when the circular push rod seat contacts the second side arm of the swing seat, the swing seat does not contact the swing seat retreat hook pin, and when the L-shaped hook claw contacts the swing seat retreat hook pin, the second side arm of the swing seat does not contact the edge of the circular push rod seat.
