According to the technical scheme, the tubular superfine dry powder fire extinguishing device is characterized in that the tubular superfine dry powder fire extinguishing device comprises a fire extinguisher body, a mounting hole is formed in the top face of the fire extinguisher body, and a spray head body is fixedly connected to the inner circle wall face of the mounting hole in a sleeved mode; the control assembly is arranged at one end of the hose and used for controlling the spraying range of the superfine dry powder, a worker presses the clamping column to enable the clamping column to enter the fixing groove through the arranged clamping column, limitation of the clamping column is lost, the worker moves a movable plate to a proper position, then the worker loosens the clamping column, and the superfine dry powder is sprayed to the superfine dry powder. And clamping columns move into clamping holes under the action of springs, so that the position of a movable plate is fixed, the spraying range of the
