Description

Technical field: [0001] The invention belongs to the sewing machine technology, in particular, a special clamping device is designed to improve the unattractiveness of the stitches when the computerized lockstitch sewing machine is started. Background technique: [0002] Ordinary computerized lockstitch sewing machine stitches are generally wound into a ball when it is started. When the computerized sewing machine is started, when the needle moves down, it drives the suture to pierce the cloth, and the excessively long thread ends are left under the fabric. Stitches affect the beauty and sewing quality of sewing fabrics. Invention content: [0003] The purpose of the present invention is to design a special thread clamping device, which is a thread clamping device of a computer lockstitch sewing machine that can prevent the formation of bird's nest stitches when the computer lockstitch machine is started. [0004] The present invention is a thread clamping device of a co...
