When the circular plate moves to the position of the clamping plate, the circular plate squeezes the inclined surface of the clamping plate, the clamping plate moves toward the pad, and the spring contracts. After the circular plate moves over the clamping plate, the clamping plate moves to the top of the circular plate under the action of the spring return elastic force. At this time, the clamping plate clamps the circular plate, thereby achieving the effect of fixing the fixing rod and the insertion rod. The result is achieved by hanging the lifting ear with the hook of the crane to lift the pressure platform body, wherein the socket for inserting the plug rod is located between the two steel bars, which strengthens the load-bearing effect of the socket and avoids the cracking of the pressure platform body as much as possible.
