Claims

[Claims for Utility Model Registration] 1. Every time a linearly reciprocating operating member is reciprocated manually or using a drive source, the moving force of the operating member is coupled to the operating member in a swingable manner. The connecting member acts on one or the other inclined surface of the chevron-shaped branch portion of the rotatable reversing member through the pressing portion of the connecting member, and the connecting member moves toward one or the other while the pressing portion slides in contact with the inclined surface. When the pressing part reaches the stopper part at the end of the inclined surface and presses the stopper part, the reversing member rotates and reverses, changing from one operation mode to the other operation mode, or from one operation mode to the other operation mode. In the mode selection reversing mechanism configured to switch from one operation mode to the other, one of the operating member and the connecting member is provided with a long groove and the other is provided with a pivot shaft, and these are fitted into each other, The long groove is lengthened in the reciprocating direction of the operating member to enable the connecting member to move relative to the operating member in the reciprocating direction of the operating member, and the pivot is used as a swing fulcrum of the connecting member, A positioning convex portion is provided on one of the operating member and the connecting member, and the other is provided with a positioning convex portion,
a positioning recess that engages with the positioning protrusion and prevents the connecting member from swinging relative to the operating member when the connecting member is moved in one direction with respect to the operating member; are connected by a spring, and the positioning protrusion and the positioning recess are always engaged by the spring force, and when the operating member is moved forward and the pressing part comes into contact with the inclined surface of the chevron-shaped branch part. , wherein the connecting member moves relative to the operating member in a direction that resists the spring force of the spring, so that the positioning convex portion and the positioning concave portion are disengaged from each other. mechanism. 2. The positioning recess has bilaterally symmetrical inclined surfaces that intersect with each other, and the positioning protrusion is engaged with the intersection of these inclined surfaces to prevent the connecting member from swinging relative to the operating member. 2. The mode selection reversing mechanism according to claim 1.
