Description

Technical Field

[0001] The utility model relates to the technical field of lockstitch sewing machines, in particular to a clothing lockstitch sewing machine with a limiting structure. Background Art

[0002] A flat-bottom sewing machine is a machine that uses a sewing thread to form a seam on the sewing material, so that one or more layers of sewing material are interwoven or sewn together. It is usually divided into two uses: thin materials and thick materials. The flat-bottom sewing machine can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. Thin materials are generally used for knitwear, underwear, shirts, and uniforms, while thick materials are generally used for various sportswear, jeans, fashion, coats, shoes and hats, leather goods, and bags.

[0003] The purpose of using a limit mechanism in a garment sewing machine is to ensure the accuracy and stability of the sewing work. However, the limit mechanisms of existing garment sewing machines have certain design limitations and are usually not easy to adjust, making it difficult for operators to accurately set them according to different sewing requirements during use. This fixed limit design limits the flexibility of the machine and cannot adapt to diverse sewing processes. In addition, the limit mechanism is often cumbersome to install and disassemble, which increases the time cost of maintenance and replacement and affects production efficiency. These problems require operators to spend more time making adjustments when sewing different styles and materials, reducing the practicality and work efficiency of the device. Utility Model Content
