The invention relates to the high voltage electrical equipment control field and discloses a nozzle connection structure, an arc extinguish chamber using the same and a breaker using the same. The nozzle connection structure comprises a nozzle and a moving contact which are respectively arranged in front and at the back; the outer side of the nozzle is sleeved by a flow guiding ring which is internally provided with a stepped hole with the front end being small and rear end being big; the rear side of the nozzle is provided with a protruded ring which protrudes outwardly; and the protruded ring is clamped in the stepped hole of the flow guide ring by a flow guide ring and the moving contact. In the nozzle connection structure, the arc extinguish chamber and the breaker, the protruded ring of the nozzle is clamped in the stepped hole of the flow guide ring by the flow guide ring and the moving contact, and a breaker nozzle is fixed on the moving contact by virtue of the flow guiding ring. Compared with the traditional direct bolt joint, the nozzle connection structure has reliable connection, reduces the possibility of looseness of the nozzle and prevents foreign matters produced by nozzle wearing.
