The vibration pile extractor is characterized in that a vibration pile extractor is arranged on a pile head, a spring vibration absorber and a rigging are hung under a lifting hook, the pile extractor is started, vibration generated by a vibrator causes resonance of a pile and a soil body, the soil body structure is damaged, the friction force between a pile body and the soil body is reduced, and the rigging is tightened to gradually extract the pile. If an eccentric block type vibrator is adopted, the eccentric block must be adjusted due to different resistance directions of pile sinking and pile pulling. The pile pulling equipment has the advantages of simple structure, high pile pulling efficiency and development prospect. The hydraulic pile extractor clamps the pile head by using the pile clamping device, the hydraulic cylinder forcibly pushes the pile clamping device to lift the pile upwards for a certain distance, and the pile is extracted section by section, so that the hydraulic pile extractor is suitable for extracting I-shaped steel or section steel piles in clay, sandy soil or soil layers containing a small amount of gravels. The pile is also pulled out mechanically, that is, the electric motor drives the winding machine to pull the pile out of the ground. The pile pulling device is convenient to use, low in cost, low in pile pulling force, heavy in equipment and low in pile pulling efficiency, and is only suitable for soft soil stratum construction. The pile is pulled out by using a double-acting pneumatic hammer, a hammer body is inverted, fixed on a pile head and hung under a rigging, the pile head in the soil is shaken to reduce the tightness between the pile and the soil, then the pneumatic hammer is started, the pneumatic hammer is hammered upwards to vibrate, the rigging is tightened, the pile is pulled out gradually, and concrete piles and other piles can be pulled out in various soil layers;

pile driver is not good to the centre gripping effect of stake at the during operation, can not adjust according to the size of stake, and this application provides a pile driver's adjustable clamping device.
