扁平アーク発生用電極の構造。[Scope of Claim for Utility Model Registration] (1) It is formed by sandwiching the upper thread and lower thread passing parts of a sewing machine, and is covered with a shell made of a high voltage insulating material except for the tip, and the tip is turned into a pointed part. A separate electrode 2 consisting of a pair of structured conductive electrodes and a shell made of a high-voltage insulator cover and sandwich the conductive electrode except for a smooth opposing surface, and the smooth opposing surface is opposed to the tip structure. 1. A spark discharge type thread trimming mechanism for a sewing machine, comprising: an arc discharge section constituted by a common electrode; and a high voltage generator that applies a high voltage current to the arc discharge section. (2) The spark discharge type thread trimming mechanism for a sewing machine according to claim 1, wherein the high voltage generator is a leakage transformer. (3) Separate electrodes consisting of a pair of conductive electrodes covered with a shell made of high voltage insulating material except for the tip, the tip of which has a pointed structure, and a shell made of high voltage insulating material to form a smooth surface. A structure of a flat arc generating electrode comprising a common electrode formed by covering and sandwiching a conductive electrode except for the opposing surface, and the smooth opposing surface facing the tip structure.
