Components of sewing machines

Generally, the sewing machine consists of four parts: the head, the base, the transmission and accessories. 
 The head of the machine is the main part of the sewing machine. It consists of four mechanisms: spining, hook, picking, feeding and auxiliary mechanisms such as winding, pressing and falling teeth. The movement of the institutions is reasonably coordinated, circulating, and sewing the stitching. 
 The machine base is divided into two forms: table plate and chassis. The table plate of the bench base acts as a supporting the head of the machine and is used as a workbench when sewing. There are many types of table panels, including one or more buckets of folding, cabinet type, writing table type, etc. The chassis of the chassis seat plays the role of supporting and storing the head, making the sewing machine easy to carry and keep. 
 The transmission part of the sewing machine consists of parts such as rack, hand shaker or motor. The rack is the pillar of the machine, supporting the table and pedal. When used, the operator tramples on the foot pedal, drives the rotation of the belt pulley through the crank, and then rotates through the belt belt motor head. Most hand shakers or motors are installed directly on the nose. 
 The accessories of the sewing machine include needles, shuttles, knives, oil kettles, etc.
