In addition, the electric clamping jaw 15 clamps the wire end and cooperates with the first telescopic cylinder 14 to move horizontally, and at the same time, the slide plate 9 moves horizontally under the action of the third rotary motor 25 driving the threaded rotating shaft 7 to reset, so that the wire end clamped by the current electric clamping jaw 15 is located at the end of the string rod 5. The electric clamping jaw 15 cooperates with the first telescopic cylinder 14 to transport the clamped wire end together with the wire at the end of the string rod 5 to the knotting machine 19 to be cut and knotted. At this time, the workpiece packed by threading in the placement groove 16 is inclined and slides under the action of the second telescopic cylinder 18 cooperating with the rotating shaft 17, so as to facilitate the placement groove 16 to slide and fall, facilitating subsequent collection.
