The second motor 423 is a servo motor, and the output shaft of the second motor 423 is fixedly connected with the end of the third air cylinder 422 away from the three-jaw chuck 421. When the third air cylinder 422 controls the three-jaw chuck 421 to open and close and grip the top end of the copper wire, the second motor 423 works and drives the third air cylinder 422 and the three-jaw chuck 421 to rotate, so that the copper wire is twisted.

By arranging the second sliding rail 540 and the second sliding block 550, the trajectory of the movement of the second pneumatic scissors 510 in the direction close to the feeding tool 210 can be limited, so that the second pneumatic scissors 510 can accurately move to the area above the feeding tool 210. During the movement of the feeding tool 210 to the wire twisting position, the second driving mechanism 530 drives the third support 520 to move in the direction away from the first sliding rail 220, so as to reserve the movement space of the feeding tool 210; after the wire twisting operation is completed, the second driving mechanism 530 drives the third support 520 to move in the direction close to the first sliding rail 220, so as to perform the end shearing of the copper wire of the product in the feeding tool 210.

Because the product needs to be arranged, twisted and cut at one time, a plurality of semicircular grooves are arranged side by side on the first finger 622 and the second finger 623 to limit the plurality of copper wires at the same time.
