When the first positioning post is high above the foundation, rotate the second screw. The rotation of the second screw can drive the piston plate to move. During the movement, it can squeeze the hydraulic oil on one side of the oil reservoir into the hydraulic cylinder, and squeeze the hydraulic oil at one end of the hydraulic cylinder into the other end of the oil reservoir. This can drive the frame column and the third rotating frame to move downward until the first positioning post contacts the top of the foundation. Then, place the first blocking plate in the positioning groove so that the first rotating frame forms a complete mold frame. Then, pour the mold through the pouring hole on the frame column.

7. The method of using the rapid positioning, leveling, and stabilizing device for precast frame columns and cast-in-place foundations according to claim 6, characterized in that: When it is necessary to dismantle the mold frame, positioning frame, and fixing frame, turn the L-shaped rotating block to lock it onto the fixing block. Then, rotate the oil reservoir in the opposite direction to cause the hydraulic oil inside to flow in the opposite direction, which will cause the piston plate to retract. During the retraction process, the second rotating frame will move upward, and the upward movement of the second rotating frame will cause the first rotating frame to move upward, thus performing the demolding work until the first and second rotating frames are separated from the concrete. Then, remove the first rotating frame, the first blocking plate, the second rotating frame, the second blocking plate, the third rotating frame, and the third blocking plate in sequence.
