Impact door breaking hammer

The invention provides an impact door breaking hammer, relates to the technical field of fire rescue equipment, and solves the technical problems that a traditional door breaking hammer in the prior art is heavy in weight, large in size, strenuous in manual impact operation, not easy to carry, high in operation risk and low in rescue efficiency. The invention provides an impact door-breaking hammer which comprises a pneumatic driving part, a fixed part and a sliding part, and the pneumatic driving part is used for providing compressed gas to drive the sliding part to perform impact action; the air inlet end of the fixed part is connected with the pneumatic driving part, and the sliding part is slidably connected with the fixed part. Through the synergistic effect of the pneumatic driving part, the fixed part and the sliding part, the pneumatic driving part provides compressed gas to serve as a power source to drive the sliding part to rapidly and accurately complete the impact action along the fixed part, eff
