PROBLEM TO BE SOLVED: To provide a pruning shears capable of easily and securely cutting off both a twig and a thick branch.SOLUTION: A pruning shears 1 in which a cutting blade 10 having a convex-shaped blade part 11 curved from a base part side toward a tip side in a convex shape and a receiving blade 20 having a concave-shaped blade part 21 curved from a base part side toward a tip side in a concave shape are rotatably connected about a support shaft 30, in which the concave-shaped blade part 21 is formed such that a minimum distance from the convex-shaped blade part 11 at each portion reduces via a narrow part S after the distance is gradually increased from the base part side toward the tip side, and when the cutting blade 10 is rotated in a closing direction with respect to the receiving blade 20, the narrow part S moves toward the base part side of the concave-shaped blade part 21.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 細い枝から太い枝まで容易且つ確実に切断することができる枝切り鋏を提供する。【解決手段】 基部側から先端側に向けて凸状に湾曲する凸状刃部11を有する切刃10と、基部側から先端側に向けて凹状に湾曲する凹状刃部21を有する受刃20とが、支軸30周りに回動可能に連結された枝切り鋏1であって、凹状刃部21は、各部位における凸状刃部11との間の最小距離が、基部側から先端側に向けて徐々に増加した後に狭窄部Sを経て減少するように形成され、受刃20に対して切刃10を閉じる方向に回動させると、狭窄部Sが凹状刃部21の基部側に向けて移動するように構成されている。【選択図】 図1
