When the reel body rotates relative to the reel connector, the driving fluted disc drives the follow-up fluted disc to rotate, so that the valve body is controlled to rotate to achieve opening or closing of the valve, the structure is simple, maintenance is convenient, a user can operate the valve easily, and the user can conduct self-rescue type fire extinguishing in the first time before a firefighter arrives in a fire disaster.
