摘要： A thread guide holder device comprises a thread guide holder which is mounted on a spool stand base and has thread guides each for guiding a thread therethrough, wherein the thread guide holder is mounted on the spool stand base by way of damping materials. As a result, it is possible to restrain the oscillation of the thread guide holder during sewing operation so as to smoothly draw out the threads through the thread guides of the thread guide holder and consequently prevent irregular stitches and restrain an eye-offensive oscillation of the thread guide holder.

摘要： A stitch balancing thread tension device for a sewing machine, the body of which is inserted into the opening portion of the sewing machine body, wherein the thread tension device body for supporting a stem on which a pair of tension discs are fit, comprises a projecting portion which contacts the outer side surface of the sewing machine body and pawls which are retained at the circumferential edge of the opening portion by the inner side surface of the sewing machine body for clamping the sewing machine body therebetween. The pawls are elastically invaginable into the thread tension device body to release the sewing machine body from clamping. Since the thread tension device can be attached to or detached from the sewing machine body in one-shot operation, the operability is remarkably improved in efficiency.

摘要翻译： 一种用于缝纫机的线圈平衡线张力装置，其主体插入到缝纫机主体的开口部分中，其中用于支撑杆的一个张紧装置本体用于装配一对张紧盘， 与缝纫机主体的外侧面接触的部分，以及通过缝纫机主体的内侧面保持在开口部的周缘的爪部，用于将缝纫机主体夹持在其间。 棘爪弹性地不能进入线张力装置主体以使缝纫机主体不被夹紧。 由于可以在一次性操作中将线张力装置安装到缝纫机主体上或从缝纫机主体拆卸，所以效率显着提高了可操作性。
