PROBLEM TO BE SOLVED: To provide a pruning saw reducing labor of a worker.SOLUTION: This pruning saw 10 includes a single-edged saw body 2 fixed to the edge of a long operation stick 1. Furthermore, the pruning saw 10 includes a swing plate 3, a clasp plate 4, a first spring member 5, and a second spring member 6. The swing plate 3 is rotatably connected to the edge of the operation stick 1. The clasp plate 4 is rotatably connected to the edge of the swing plate 3, and has an edge intersecting the saw body 2 and extending. The clasp plate 4 has on one side edge, a plurality of thrusting blades 4a to thrust into a branch Br, and cuts the branch Br by reciprocating the saw body 2 in a condition that the thrusting blade 4a holds the branch Br. Since the resultant force of the spring force of the first spring member 5 and the second spring member 6 energizes a blade 2a of the saw body 2 toward the branch Br, the saw body 2 hardly comes off from a cut face of the branch Br.COPYRIGHT: (C)2012,JPO&INPIT【課題】作業者の労力を軽減できる枝切り用鋸を提供する。【解決手段】枝切り用鋸10は、長尺の操作棒1の先端部に固定された片刃の鋸本体2を備える。又、枝切り用鋸10は、揺動板3と留め金板4、及び第1ばね部材5と第2ばね部材6を備える。揺動板3は、操作棒1の先端部と回動可能に連結している。留め金板4は、揺動板3の先端部と回動可能に連結し、先端部が鋸本体2と交差して延びている。留め金板4は、枝Brに突き刺し可能な複数の突き刺し刃4aを一方の側縁に有し、突き刺し刃4aが枝Brを保持した状態で、鋸本体2を往復動して枝Brを切断する。第1ばね部材5及び第2ばね部材6は、それらのばね力の合成力が鋸本体2の刃2aを枝Brに向かって付勢するので、鋸本体2が枝Brの切り口から外れ難くなっている。【選択図】図4
