This not only disperses the supporting force of the large piston, increases the service life of the large piston and the hydraulic structure, but also if a rod explosion occurs and the supporting force of the large piston on the heavy object decreases, the first connecting arm and the second connecting arm will continue to support the heavy object, thus avoiding the phenomenon that when the jack cylinder explodes, there is no other supporting force acting on the base of the heavy object, causing the heavy object to quickly drop.

[0023] Through the above technical solution, the bottom plate 2 is placed on the ground, the material is placed on the surface of the placing plate 14, the controller 3 is started, the controller 3 controls the transmission mechanism to work, so that the transmission mechanism drives the hydraulic jack body 1 to perform hydraulic pressure, so that the hydraulic jack body 1 drives the material to rise. While the hydraulic jack body 1 rises, the sliding rods 13 drive the springs 12 to be compressed on the inner walls of the limiting rods 11 for buffering, and at the same time drive the clamping mechanisms to flip, so that the clamping mechanisms clamp and fix the material. The upper surface of the hydraulic jack body 1 contacts the lower part of the placing plate 14.
