The invention relates to the technical field of fire fighting equipment, and discloses a fire axe with adjustable handles based on fire fighting engineering. The fire axe comprises an axe body. The right side of the axe body is fixedly connected with a first axe handle, the left end of the surface of the first axe handle is fixedly connected with a first limit ring, the right side surface of the first limit ring is movably connected with a first connecting sleeve, the inner wall of the first connecting sleeve is connected with the surface of the first axe handle through threads, a first circular arc groove is arranged inside the first axe handle, and a second circular arc groove penetrating the right end of the first axe handle and communicating with the inside of the first circular arc groove is arranged on the right side surface of the first axe handle. According to the fire axe with the adjustable handles based on fire fighting engineering, the distance between the first axe handleand the second axe handle is enlarged through a threaded rod and a threaded hole by turning the first axe handle and the second axe handle in the opposite directions, so that the length of the fire axe can be adjusted, thereby realizing the purpose of adjusting the length of the fire axe.
