The hollow seat (609) can drive the air blowing head 1 (611) and the air blowing head 2 (612) to move back and forth in the vertical direction, and the air pump (614) can deliver air into the hollow seat (609), and the air is discharged through the air blowing head 1 (611) and the air blowing head 2 (612). In this way, the air blowing head 1 (611) and the air blowing head 2 (612) can repeatedly and evenly blow air to the drill bit (5), blow off the waste chips, and ensure the subsequent drilling effect of the drill bit (5) on the circuit board (10).
