摘要： A driving clutch device for a sewing machine includes a drive shaft, a passive member, a clutch seat, an actuating seat, a power unit, and a clutch member. Through fixing the passive member and the clutch seat onto the drive shaft, rotatably disposing the actuating seat, the drive shaft, and returnably disposing the clutch member to the clutch seat, the clutch seat and the actuating seat are able to move synchronously when the clutch member is in the engaged position, but not to move synchronously when the clutch member in the disengaged position, thereby achieving the driving and clutch controls only by the clutch member, the passive member, the clutch seat and the actuating seat. Therefore, the driving clutch device is simpler and the driving is more direct and instant, thereby reducing assembly costs and the error of action coordination.

摘要： A thread take-up lever for a sewing machine is mounted on the sewing machine and can prevent a thread from disengaging from a thread-receiving portion. The thread take-up lever is disposed with a C-shaped thread-receiving portion having an open recess. Adjacent to the open recess is provided at least one positioning portion for fixing a thread-stopping member. One end of the thread-stopping member is fixed to the positioning portion, and an elastic stopping portion extends from the other end of the thread-stopping member. The stopping portion is formed with a free end abutted against an inner periphery of the open recess. The free end can be pushed away by the thread, and then the free end will automatically return to its original position immediately to abut against the open recess again, thus forming a structure to prevent the thread from disengaging from the thread-receiving portion.
