What are the components of a sewing machine?

The general sewing machine is composed of four parts: head, seat, transmission and accessories.

　The nose is the main part of the sewing machine. It consists of four mechanisms: thorn material, hook wire, pick wire, and feed material, and auxiliary mechanisms such as winding, pressing material, and falling teeth. The movement of each institution is reasonably coordinated, circulating, and stitching the suture.

The chassis is divided into two forms: platform and chassis. The tabletop of the tabletop seat acts as a support head and is used as a workbench when sewing. The table has a variety of styles, including a bucket or multiple folds, cabinets, and writing desktops. The chassis of the chassis acts as a support and storage head, making the sewing machine easy to carry and keep.

The transmission part of a sewing machine consists of a frame, a hand shaker or an electric motor. The frame is the backbone of the machine and supports the platform and pedal. When used, the operator steps on the pedal, drives the pulley through the crank, and drives the head to rotate through the belt. Most hand shakers or motors are directly mounted on the nose.

The accessories of the sewing machine include needles, shuttle cores, screwdrivers, oil pots, etc..
