[0024] In addition, a rotating rod 11 is fixedly passed through the front end of the bending punch clamp 3, and a through hole 12 is opened at the front end of the bending punch 4. The rotating rod 11 is arranged in the through hole 12 to support the bending punch 4 to rotate so that the bending punch 4 can swing when bending. A nut 13 is sleeved on the rotating rod 11, and the outer wall of the rotating rod 11 is processed with threads. The nut 13 is threadedly connected to the rotating rod 11, and the rear end of the nut 13 contacts the front end of the bending punch 4.
