When the prefabricated pile is taken out, first, the oil cylinder one 8 is extended to move the core 10 left with the prefabricated pile. At the same time, the motor one 55 is started to drive the steel bar seat 52 to move left with the prefabricated pile. When the prefabricated pile leaves, the core 10 is moved right away from the prefabricated pile through the shortening of the oil cylinder one 8.
