<P>PROBLEM TO BE SOLVED: To solve problems wherein a means for locking a pressure accumulation elastic body is defined as the elasticity of a material, thereby often causing the fatigue fracture, the pressure accumulation elastic body has a cut portion to often cause the fatigue fracture, the pressure accumulation elastic body sometimes slightly moves to obstruct an operation, and an energizing means for lifting the pressure accumulation elastic body may cause fatigue fracture in a tacker type stapler. Ž<P>SOLUTION: The pressure accumulation elastic body is molded at a predetermined V-shaped opening to eliminate the cut part and is configured to be lifted by a spring to greatly reduce the fatigue fracture. The pressure accumulation elastic body is locked by a journalled trigger to eliminate the fatigue fracture of an engagement means. The pressure accumulation elastic body and a blade are retained by a hook part to prevent the slight movement of the accumulation elastic body. A hook button facilitates the extraction of a magazine to facilitate the replacement of staples. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
