Description

Technical Field

[0001] The utility model relates to the field of sewing machine shell processing, in particular to a sewing machine shell polishing tool. Background Art

[0002] A sewing machine is a mechanical device used to sew, join and mend fabrics. It plays a key role in the textile and tailoring industries and is also one of the common tools in household life. A sewing machine uses one or more needles to form seams by penetrating the fabric and carrying threads. These threads are formed into different seams through different settings, such as overlock, straight line, zigzag, etc. The sewing machine is still a very practical tool in modern life, whether it is for simple repairs at home or large-scale manufacturing of clothing in industrial production.

[0003] A sewing machine shell is provided on the outside of the sewing machine. The shell of the sewing machine is usually made of a strong material to protect the internal mechanical parts and provide a stable working platform. Common materials for sewing machine shells include metal, plastic or a combination thereof. Metal shells are usually stronger and more durable and are suitable for industrial-grade sewing machines, while plastic shells make household sewing machines lighter. During the production of the sewing machine shell, in order to ensure the flatness and smoothness of the shell, the sewing machine shell needs to be polished. The current polishing tool is not convenient for pushing the shell during polishing and needs to be pushed manually. Manual pushing is less safe and can easily cause the grinding wheel to scratch the worker, causing inconvenience in use. Therefore, a technician in this field provides a sewing machine shell polishing tool to solve the problems raised in the above background technology. Utility Model Content
