A plurality of elastic components 60 are provided between the first punching plate 40 and the second punching plate 50. The elastic component 60 elastically connects the first punching plate 40 and the second punching plate 50. During punching, the second punching plate 50 abuts against the material carrier 210 to press the sheet material 80. The first punching plate 40 moves downward, driving the punch assembly 10 to move downward as well. The second punching plate 50 presses the sheet material 80, and then the first punching plate 40 continues to move downward. At this time, the distance between the first punching plate 40 and the second punching plate 50 becomes smaller, the elastic component 60 is compressed, the punch assembly 10 protrudes from the second punching plate 50, and punches the explosion-proof plate 81 on the sheet material 80 through the corresponding second through hole 51, thereby improving the stability of the punch assembly 10.
