Claims

[Claims for Utility Model Registration] An operating shaft 2 having a cam portion at one end and rotatably supported on the machine frame.
, a rotating body 7 that has a cylindrical shaft that loosely fits on the operating shaft and always rotates in conjunction with the drive source, and an interlocking body 11 that has a cylindrical shaft with the same diameter as the cylindrical shaft of the rotating body and is fixed to the operating shaft. , a clutch spring 13 formed in a spiral shape and arranged so that the inner peripheral surface of one end is in frictional engagement with the outer periphery of the cylindrical shaft of the rotating body, and the other end is fixed to the interlocking body; A claw part body 14 has a claw that is loosely fitted so as to cover and protrudes to the outer periphery, and a protrusion that can be engaged with one end of the spring is provided on the inner periphery of the claw part body 14. The locking portions are arranged opposite to each other across the axis of the actuating shaft so that the other enters into the rotation path of the claw and the other exits, and engages the claw of the claw body as it enters and prevents rotation of the claw body. a clutch lever 17 having a clutch lever 17;
In a control device that transmits and cuts off the rotational force of a rotating body to and from an operating shaft in connection with expanding and contracting the inner diameter of a clutch spring through engagement and disengagement with a claw body, the operating shaft or The free end is connected to the operating shaft or the outer periphery of the rotating body so that the rotation of the rotating body that is interlocked with the rotating body is always allowed in the direction in which the rotating body rotates, but is blocked in the opposite direction when the inner diameter of the clutch spring is expanded. A reversal prevention body 29 whose base end is rotatably supported on the machine frame so as to be joined to a surface, and an elastic body 31 that normally applies an acting force to press the reversal prevention body against an operating shaft or a rotating body. Sewing machine control device.
