O Utility Model Registration Claims A crank 3 fixed to the drive shaft 2 and a linking rod 6 pivoted to the movable shaft 5 are rotatably connected by a rod 1, and the shaft of the linking rod 6 with the rod 1 is rotatably connected. The fulcrum is further rotatably connected to the other end of a connecting rod 8 having the same diameter as the connecting rod 6, which has one end pivoted to an arm 10 fixed to the female shaft 9, and is linked to the operation of the other operating member. A link mechanism for swinging the movable shaft about a fixed axis is separately provided, and when the operating member is operated and the movable shaft is rotated via the link mechanism, the female shaft 9
When the vertical stroke of the upper knife 13 fixed to the upper knife 13 changes and the movable axis coincides with the fulcrum of the connecting rod 8 and the arm 10, the movable knife 13 attached to the knife axis moves to the bottom dead center where it does not interfere with sewing work. A sewing machine knife mechanism that is designed to stop in an inoperative position.
