The invention relates to a rapid adjusting device for supports of lifting appliances. The rapid adjusting device is characterized by comprising sliding grooves formed in the left side and the right side of lower arms of the lifting appliances; sliding blocks are installed inside the sliding grooves and are connected with the supports; through holes are formed in the sliding blocks and are internally provided with screws; glands are arranged at the outer ends of the through holes; one end of a screw body of each screw penetrates out of the corresponding gland and is connected with a handle; the screws are sleeved by springs; one end of each spring abuts against the corresponding gland; the other end of each spring abuts against a nut of the corresponding screw; multiple positioning holes into which the nuts of the screws can be inserted are formed in the bottoms of the sliding grooves; end baffles are installed at the lower ends of the sliding grooves. The rapid adjusting device for the supports of the lifting appliances can rapidly and conveniently meet the requirement of an automobile factory for rapidly adjusting the positions of the supports of the lifting appliances, and the working efficiency is greatly improved compared with that of a traditional mechanism.
