The spring 404 is compressed after being squeezed by the pressing disc 405. Subsequently, the sliding columns 403 rise from inside the positioning holes 10. Then, the two L-shaped clamping grooves 2 of the connecting frame 1 are passed through the supporting rod 3 and snapped into the L-shaped clamping grooves 2. Then, the hand lifting the lifting block 408 is released. Under the tension of the spring 404, the sliding columns 403 are pressed into the positioning holes 10 to fix the supporting rod 3 and prevent it from falling off. Then, an external crane is connected to the lifting hook 5 to lift the connecting frame 1 upward. Subsequently, the supporting rod 3 drives the supporting seat to be lifted upward. When it moves to a suitable position, the staff place the lifting device on the ground.
