The invention provides an automatic control jack, and relates to the technical field of jacks. The automatic control jack comprises a jack base and a hydraulic oil supply device, wherein an oil supply pipeline is connected between the jack base and the hydraulic oil supply device, a flow regulating valve corresponding to the oil supply pipeline is installed in the center of the front end of the jack base, lifting hydraulic cylinders are fixedly connected to the corners of the center of the jack base, the top ends of piston rods of the multiple lifting hydraulic cylinders are fixedly connected with a fixing plate, a mounting base is fixedly connected to the top of the fixing plate, a plurality of fixing screws corresponding to the fixing plate are fixedly connected to the peripheral side of the mounting base, and a top supporting plate is arranged at the top of the mounting base. Through the design of the jack, the jacking hydraulic cylinder, the hydraulic oil supply device, an elastic reset mechanism and an automatic control mechanism, after a heavy object is placed on the supporting plate, the supporting plate can automatically trigger a switch after being stressed, and therefore the jack can automatically complete jacking and lifting of the heavy object.
