PURPOSE: A hitting tool of a pile is provided to hit the pile to the correct direction and posture by the size of the pile, and to reduce the impact applied to a worker. CONSTITUTION: A cylindrical main body (20) includes openings on the upper and lower sides, and a handle (21). A hitting weight (30) is installed inside a main body to be moved to the vertical direction. A control means (40) is installed to vary the induction diameter by plural control plates (45) on the lower side of the main body. The control means includes a circular ring (41) combined to the arbitrary position of the main body by interposing an adjusting bolt (42). The control plates are connected to the circular ring by interposing a support pin (43) and a hinge (46), respectively. The hitting weight is connected to an extension spring from the lower side, and is supported by a compressed spring (34) on the upper side. The control plates are connected to the support pin using an elongated groove (45a). |
