7. The tapping device for miniature circuit breaker machining of claim 1, wherein: and anti-skid rubber pads can be fixedly coated on the opposite sides of the two clamping plates (16).

8. The miniature circuit breaker tooling tapping apparatus of claim 5, wherein: the two opposite sides of the circular plates can be respectively provided with a positioning square groove and a positioning square column which are matched with each other, and when the two circular plates are fixed by the locking bolts, the positioning square column is movably inserted into the positioning square groove.

9. A tapping method for processing a miniature circuit breaker is characterized in that: use of an opening device according to any of claims 1-8 for opening a miniature circuit breaker, comprising in particular the following operating steps:

s1: placing the miniature circuit breaker shell to be perforated between two clamping plates (16), rotating a rotating wheel to drive a screw rod to rotate, and driving a moving plate (4) to approach the direction of a fixed plate (3) by using the rotating screw rod, so that the two clamping plates (16) clamp the miniature circuit breaker shell to be perforated;

s3: the turntable (2) is driven to rotate by a servo motor, and the gear (8) is meshed with the gear blocks (9) to enable the gear (8) to rotate until the tail ends of all groups of gear block areas are about to leave, so that the miniature circuit breaker shell to be perforated is driven to perform transposition;

s4: when the small-sized circuit breaker shell to be opened is switched to the surface to be opened, the air cylinder (10) drives the lifting disc (11) to move downwards, so that the rotary drill rod (13) completes opening of the surface to be opened on the small-sized circuit breaker shell to be opened;

s5: when the hole is opened, an air pump (142) is started to pump air into the annular plate (141), and the air curtain wall with an annular structure is blown out through an air outlet channel, so that scraps in the hole opening process are prevented from being dissipated into a working environment;

s6: and after the small circuit breaker shell to be perforated is manually fed from the initial feeding position under the rotation of the turntable (2), replacing the small circuit breaker shell to be perforated up and down for perforation.
