【作用】前記のように構成される本発明は以下に述べる
作用を奏する。The present invention configured as described above has the following effects.
【００１３】台金における凹状溝において、台金と押体
とに穿設した受孔および掛け孔へ操作工具を掛け合せ、
受孔を支点として押体を台金の求心方向へ回動させる
と、その弾性片に抗して該押体が凹状溝内で沈む。In the concave groove of the base metal, the operating tool is engaged with a receiving hole and a hook hole formed in the base metal and the pressing body,
When the pressing body is rotated in the centripetal direction of the base with the receiving hole as a fulcrum, the pressing body sinks in the concave groove against the elastic piece.
【００１４】したがって、押体と裏座との間に隙間がで
きて、裏座の移動が押体に対して自由となるので、凹状
溝の他側壁と裏座との間へ刃物体を挿嵌する。Therefore, a gap is formed between the pressing body and the backing body, and the backing body is free to move with respect to the pressing body, so that the blade object is inserted between the other side wall of the concave groove and the backing body. Fit.

押体を台金の周面部へ向かって押し上げるから、この弾
性により刃物体が凹状溝内に固着される。When the operating tool is hung over the receiving hole and the hook hole and the push body is returned, the inclined surface of the push body returns to the original position while contacting the wedge surface of the concave groove. The pressing force acts on the other side wall of the groove and the spring force of the elastic piece pushes the pressing body toward the peripheral surface of the base metal, so that the blade body is fixed in the concave groove by this elasticity.
【００１６】このとき、凹状溝の他側壁面へ刃物体にお
ける側面の全面が均一に当接し、刃物体には、一律な摩
擦力が得られて強固な固定がなされる。At this time, the entire surface of the side surface of the blade object uniformly contacts the other side wall surface of the concave groove, and a uniform frictional force is obtained on the blade object so that the blade object is firmly fixed.
【００１７】また、刃物体の取り外しにおいては、操作
工具を受孔と掛け孔とへ掛けて、受孔を支点として押体

押体が凹状溝内で沈む。In removing the blade object, when the operating tool is hung on the receiving hole and the hook hole, and the pressing body is turned in the centripetal direction of the base metal with the receiving hole as a fulcrum, the pressing member is opposed to the elastic piece. The pressing body sinks in the concave groove.
【００１８】すると、押体と裏座との間に隙間ができ
て、裏座の移動が押体に対して自由となるので、凹状溝
の他側壁と裏座との間から刃物体を引き抜くと取り外せ
る。[0018] Then, a gap is formed between the pressing body and the backing body, and the backing body is free to move with respect to the pressing body. Therefore, the blade object is pulled out from between the other side wall of the concave groove and the backing body. And can be removed.
