The clamping piece is hinged with the connecting rod, so that the clamping piece can swing left and right around the connecting point, and clamping is facilitated. The horizontal pole is parallel with the connecting rod, and the cover has the spring on the horizontal pole, and the one end of holder cup joints on the horizontal pole, and with spring coupling, realize the reset of holder horizontal hunting. The metal wire is discharged from the discharge port, the metal wire is cut through the positioning structure, the connecting rod can move left and right to drive the clamping part to move left and right, and the clamping piece is matched with the positioning structure to convey the metal wire to the end part forming die.
Preferably, the clamping piece is a metal rod capable of swinging left and right, a positioning structure is arranged on the left side of the clamping piece, a U-shaped groove is formed in the positioning structure, and the opening of the U-shaped groove faces towards the lower end of the clamping piece. The left side of holder is equipped with location structure, and location structure's U-shaped groove opening is towards the holder lower extreme, makes the holding structure can cooperate location structure to press from both sides the metal wire tight.
Preferably, the cross bar is fixed above the connecting rod, the left end of the spring is fixed at the left end of the cross bar, and the right end of the spring is fixed at the upper end of the clamping piece. The cross bar is fixed above the connecting rod and is parallel to the connecting rod, and can move along with the connecting rod. The left end of the spring is fixed at the left end of the cross rod, the right end of the spring is fixed at the upper end of the clamping piece, and when the clamping piece moves rightwards along with the connecting rod, the spring can play a role in enabling the clamping piece to reset; meanwhile, the spring enables the clamping piece to be matched with the positioning structure to send the metal wire to the front of the end part forming die.
Preferably, the upper end of the clamping piece is sleeved on the cross rod, and the middle part of the clamping piece is hinged with the connecting rod. The clamping piece can move left and right along with the cross rod and the connecting rod, and the clamping piece is hinged to the connecting rod, so that the clamping piece can swing left and right, and metal wires can be clamped tightly.
Preferably, the two extension springs are respectively positioned at the front side and the rear side of the left end of the connecting rod. The tension spring acts to make the link more tensioned as it moves side to side.
Therefore, the utility model has the advantages of as follows: the clamping structure can be matched with the positioning structure on the left side to clamp the sheared metal wire and send the metal wire to the front of the end part forming die; the clamping structure is sleeved on the cross rod and connected with a spring, so that the metal wire can be clamped by the clamping structure; the left end of the connecting rod is provided with an extension spring, so that the connecting rod has tension when moving left and right.
