Lifting hook for constructional engineering

The utility model discloses a lifting hook for constructional engineering, which relates to the technical field of lifting hooks for constructional engineering and comprises a fixing box, a rope fixing ring is fixedly mounted on the upper wall surface of the fixing box, a buffer trigger component is arranged in the fixing box, a connecting plate is mounted on the buffer trigger component and positioned outside the fixing box, and the rope fixing ring is fixedly mounted on the rope fixing ring. According to the lifting hook, an instantaneous force buffering process exists in the upward lifting process of the lifting hook body through the buffering trigger assembly, a rope hoisted on the lifting hook body is prevented from being broken due to the fact that the instantaneous force is too large, and when the lifting hook body hoists a heavy object, the flashing light flashes, so that the lifting hook body is prevented from being damaged. And the lifting hook is sealed and limited through the limiting assembly, so
