Therefore, in this embodiment, the inner flushing liquid flow direction of the arc discharge inner and outer flushing liquid knife handle device is as follows: the flushing adapter 300 → the liquid chamber 210 → the flushing hole 130 → the first inner flushing flow passage 120 → the second inner flushing flow passage 510. And the outer flushing liquid flow direction of the arc discharge inner and outer flushing liquid knife handle device is as follows: the flushing adapter 300 → the liquid chamber 210 → the outer flushing tube 600.
