A driving device is arranged on the execution end and is used to drive the execution end to slide left and right.

[0033] For the convenience of description, two punching holes 2 among the following several punching holes 2 are taken as an example for illustration. During use, the U-shaped plate 8 is pushed into the channel 5 formed between the intermediate block 4 and the two support blocks 3 by a feeding device and pauses at the set position of the U-shaped plate 8. The pressure device drives the execution end to press down. When the execution end is above the pressing block 6 on the right side, the execution end presses down the pressing block 6 on the right side, so that the pressing block 6 drives the punching head 7 on the right side to move downward in the corresponding punching hole 2, and further the bottom end of the punching head 7 punches a hole in the U-shaped plate 8; when the execution end is above the pressing block 6 on the left side, the execution end presses down the pressing block 6 on the left side, so that the pressing block 6 drives the punching head 7 on the left side to move downward in the corresponding punching hole 2, and further the bottom end of the punching head 7 punches a hole in the U-shaped plate 8; since the punching head 7 and the punching hole 2 on the left side are different in shape from the punching head 7 and the punching hole 2 on the right side, the execution end can be driven to slide left and right by the driving device, so that the execution end is above the pressing block 6 on the left side or the pressing block 6 on the right side, so as to realize punching holes with different hole types in the U-shaped plate 8.

[0034] In this embodiment, a plurality of mounting holes 9 are provided in the upper end surface of the mold 1 in the left-right direction. An inlay sleeve 10 is inserted into each mounting hole 9.
