The main hook is in a long strip, and the auxiliary hook is ''V''-shaped. Either side of the auxiliary hook is provided with a slot, the lower part of the main hook extends into the slot and is close to the other side, and the main hook is connected to the auxiliary hook through a bolt. The internal surface of the other side of the auxiliary hook is equipped with antiskid teeth, the lower end part of the main hook is designed as an inclined plane with the front lower than the rear, and the lower end of the main hook is provided with antiskid teeth corresponding to the antiskid teeth on the internal surface of the other side of the auxiliary hook. The lifting hook is clamped into two sides of a plate, the antiskid teeth on the internal surface of the auxiliary hook contact the lower surface of the metal plate, the main hook is pulled upward to erect gradually, the antiskid teeth on the inclined plane at the lower end of the main hook gradually grips the upper surface of the plate, and along with the rise of the main hook, the metal plate gradually gets off the ground, and under the weight influence of the metal plate, the load bearing of the main hook and the auxiliary hook increases, and the clamping between the main hook and the auxiliary hook becomes stable and reliable.
