The utility model discloses a pressure type foam fire-fighting device capable of preventing a running bag from being blocked by piezoelectricity. The device structurally comprises a water storage tank, a fixed bracket, a roller, a pipe placing frame, a rack, a water pipe seat, a piezoelectric clamping device, a pressure pipe fitting and a capsule connecting pipe, according to the utility model, the pressure pipe fitting extrudes the pressure ring arranged on the piezoelectric clamping device through water in the water pipe seat; the electric control box is used for generating piezoelectric current; the trigger frame is utilized to attract the trigger frame to be embedded into the push groove and move along the outer side of the pipe supporting piece along the gap of the push groove, then the capsule connecting pipe body is clamped to be prevented from being impacted by water flow, the situation that the capsule connecting pipe body is accumulated and blocked around a pipe opening can be effectively avoided, a
