The invention relates to a clamp and in particular relates to a flue hoisting clamp. The flue hoisting clamp comprises an extension pipe, a bracket plate connected at the bottom of the extension pipe and a flue frame connected at the top part of the extension pipe, wherein the flue frame is a square hollow straight tube which has a closed upper end and is larger than a flue, and a hook is arranged on the top surface of the outside of the straight tube; the extension pipe is composed of mutually-nested straight pipes, the length of the extension pipe in an extension state is equal to the length of the flue, the upper end of the straight pipe is arranged on the top surface of the inside of the flue frame, and an air bag is arranged between the straight tube and the extension pipe; the bracket plate is composed of two straight plates of which one ends are intersected, the intersected point of the straight plates is arranged at the bottom of the extension pipe by a locating pin, one end of the straight plate is provided with a baffle plate perpendicular to the upper end surface of the straight plate, and the lower end surface of the straight plate is provided with a spring for connecting the two straight plates. The flue hoisting clamp has the beneficial effects that when the flue is hoisted, the stressed area of the clamp and the flue wall is increased, and the flue outlet is prevented from collision.
