Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a zigzag sewing machine, in particular to a thread trimmer of the zigzag sewing machine. Background technique [0002] Zigzag sewing machine is a special sewing machine for sewing machines, also known as zigzag sewing machine or herringbone sewing, which is used for zigzag sewing with certain elastic stitches, such as bras and underwear. Commonly used are two-point machine (304 lock stitch) and three-point machine (308 lock stitch). The electronic zigzag sewing machine can set straight line, 2 o'clock, 3 o'clock, 4 o'clock, crescent-shaped, needle-shaped zigzag seams on one sewing machine, which greatly improves the equipment activity rate. [0003] Zigzag sewing machine consists of four parts: head, machine base, transmission and accessories. The machine head is the main part of the zigzag sewing machine. It consists of four mechanisms of barbed material, thread hook,...
