[Problems] The repulsive force of the spring at the final point of the cut, the operator is that itll make to coincide with the direction of applying force, it is to provide an assist scissors that can be easily cut. The apparatus includes a cutting edge 2, the cutting edge and integrally formed grip portion 4 and 5, a pair of the moving arm 6 consists of a fixed arm 7 and having a shaft 3 provided between the blade edge and the grip part and the arm 8, a disc spring shaped portion 21 having a concave shape around the center thereof in the oval, the plate spring portion 22 is extended from the disc spring shaped part, the moving arm at the distal end of the plate spring portion and a holding portion 23 for slidably holding the grip 4 in the opposite end portion side 14 and the holding portion is held in the fixed arm and the shaft near the holding portion can slide the grip consists retained assisted spring 20., when a force is applied in the grip, the disc spring shaped portion at the stage before cutting edge closing is inverted in a convex shape, and returns to the initial concave shape when the edge is closed reversing mechanism portion (protrusion 9) it was provided. .BACKGROUND【課題】切断の最終時点でバネの反発力を、操作者が力を加える方向と一致するようにしてやることで、容易に切断できるアシストハサミを提供する。【解決手段】刃先2と、刃先と一体的に形成された握り部4,5と、刃先と握り部との間に設けられた軸3とを有する移動アーム6と固定アーム7とからなる一対のアーム8と、長円形状でその中央部を中心に凹形状を有する皿バネ形状部21と、皿バネ形状部から延在された板バネ部22と、板バネ部の先端部において移動アームの握り部4に摺動可能に保持されるための保持部23とを有し、保持部と反対の一端部側14が固定アームと軸近傍において保持され、握り部において保持部が摺動可能に保持されたアシストバネ20とからなり、握り部で力を加えた場合、刃先が閉じる前の段階で皿バネ形状部が凸状に反転し、刃先が閉じたときに初期の凹形状に戻る反転機構部(突起部9)を設けた。【選択図】図1
