Secondly, the second lower cutter group 600 is matched with the second upper cutter 240, so that one-time punching action can be performed to directly punch double rows of pins, the length of the double rows of pins can be kept consistent, and the processing precision is improved. Thirdly, when the length of the pin to be punched is adjusted for the dual in-line integrated circuit, the thickness of the supporting leg 6220 is adjusted through the second adjusting plate 622, so that the overlapping distance between the auxiliary connecting part 6211 and the punching surface of the second lower cutter 610 can be adjusted, only the second adjusting plate 622 needs to be replaced, not only the length of the upper pin and the lower pin can be synchronously adjusted in a consistent manner, but also the sizes of the two sides of the pin placing groove 6212 can be synchronously adjusted in a consistent manner, the accuracy of the adjusting precision is higher, and the adjustment of skew distortion is avoided. The third lower cutter 630 at the lower part plays a role in supporting and reinforcing, the length of the corresponding pin to be punched can be obtained only by the step of replacing the second adjusting plate 622, the adjusting synchronism capability is enhanced, and the adjusting purpose can be realized without any distance measuring tool.

The above are merely embodiments of the present invention, and do not limit the scope of the claims of the present invention.
