PROBLEM TO BE SOLVED: To provide a multipurpose type thrust hammer capable of easily implanting and pile-extracting even a pile of a high stature, and also usable even for cutting.SOLUTION: An iron bar 1 is inserted into a metallic cylindrical weight W, and when stoppers R, R1 and R2 of becoming a slipping-out stopper are separately fixed to at least both, since impact force can be transmitted to the iron bar 1 by vertically moving the cylindrical weight W, the root of a plant can be cut or firewood is split or a pile can be implanted and extracted by using this impact force, so that uses are great many. For cutting the root, one end of the iron bar 1 is pointed in s cutter shape, and the pile is implanted by using a cap for closing one end of a cylindrical body for covering a high pile and mutually providing two L-shaped corners in parallel.SELECTED DRAWING: Figure 1 |
