[0026] Specifically, the first positioning plate 101 and the second positioning plate 102 are fixedly connected by a limiting frame 103, and two cold heading devices 104 are installed at the bottom of the limiting frame 103 (an upper template is installed at the bottom of the cold heading device 104, and the fasteners are cold headed through the upper template), one of the cold heading devices 104 is located above the first placement plate 201, and the other cold heading device 104 is located above the second placement plate 202.

[0027] Furthermore, a rotating rod 206 is rotatably arranged between the first placing plate 201 and the second placing plate 202, and a driving gear column 207 is fixedly arranged on the side surface of the rotating rod 206, and the first gear plate 203 and the second gear plate 204 are both engaged with the driving gear column 207.
