Since each locking bolt 62 is against the side wall of the corresponding clamping plate 4 at this time, the threaded sleeve 52 does not rotate synchronously with the screw rod 71, so the screw rod 71 can drive the two threaded sleeves 52, the two connecting blocks 5 and the two clamping plates 4 to move toward each other, so that the part is clamped and fixed by the two clamping plates 4, and then the second motor 82 is started to drive the drill bit 83 to rotate, and the height of the drill bit 83 is adjusted by the electric telescopic rod 8. Punch holes in the parts; when the specifications of the parts that need to be punched change, before starting the first motor 7, loosen the two locking bolts 62 first, and then turn each knob 6 respectively to drive the rotating disk 61 and the rotating rod 63 to rotate, and through the transmission of the first gear 42 and the second gear 54, drive the threaded sleeve 52 to rotate, so that the threaded sleeve 52 drives the connecting block 5 and the clamping plate 4 to move axially along the screw rod 71, and observe the moving distance through the scale 32. After moving into place, tighten the two locking bolts 62 and abut against the side wall of the corresponding clamping plate 4, and then punch holes in the above manner.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
