The invention belongs to the technical field of lifting appliances, in particular to a lifting appliance. The lifting appliance comprises a lifting ring, a first shell and a second shell. The liftingappliance further comprises a driving unit, a grabbing unit, a clamping unit and a controller. On the one hand, the lifting ring is pulled, and according to the size of the object to be grasped, through the mutual cooperation between a first cylinder, a differential mechanism, a first worm, a first slide block, a rack, a first gear, a second worm, a third worm and a second slide block, the secondworm and the third worm rotate towards the side close to the first gear, so that the grasping unit tightly clamps the object, and the object is prevented from falling off in the lifting process, so that the lifting safety of the object lifting is improved; and on the other hand, during lifting of the lifting ring, a fixing plate presses a first air bag, and the gas generated by the first air bag is used for lifting the object, so that additional power equipment is avoided, the overall weight of the lifting tool is increased, the weight of the lifting tool for lifting the object is influenced,and the practicability of the lifting tool is improved.
