Claims

[Claims for Utility Model Registration] The device is movably supported between the throat plate and the thread ring catcher, catches the thread when the thread is cut, and cuts the thread with a fixed knife fixed at a proper position on the sewing machine. In a thread cutting device for a sewing machine equipped with a movable knife, a fixed knife adjusting body 5 is attached to a base 1, and a fixed knife receiving member 6 to which a fixed knife 2 is fixed is supported from the axial direction of a support hole 5c of the fixed knife adjusting body 5. It is rotatably inserted into the hole 5c, and the fixed knife receiving member 6 rotates under the sliding action of the surface of the blade portion 2a of the fixed knife 2 and the movable surface 4b of the movable knife 4, and the blade of the fixed knife 2 is rotated. Part 2a
A thread trimming knife adjustment mechanism for a thread trimming device of a sewing machine, characterized in that the parallelism between the surface of the movable knife 4 and the movable surface 4b of the movable knife 4 can be automatically adjusted to be appropriate.
