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
【課題】背丈の高い杭でも容易に打ち込みや杭抜きができ、しかも切断にも利用できる多用途型のスラストハンマーを提供する。【解決手段】金属製の筒状重しＷに鉄棒１を挿通して、少なくとも両方に抜止めとなるストッパーＲ、Ｒ１，Ｒ２を離して固定してあると、筒状重しＷを上下動して鉄棒１に衝撃力を伝達できるので、この衝撃力を利用して植物の根切りをしたり、薪割りをしたり、杭の打ち込みや抜き取りなどが可能となり、用途は多大である。根切りのために、鉄棒１の一端を刃物状に尖らせてあり、高い杭に被せる筒体の一端を閉じると共に２本のＬ字状の角を互いに平行に設けたキャップを使用して杭打ちする。【選択図】図１
