Main shaft connecting rod assembly

Technical Field

The utility model relates to the field of textile technology, especially, relate to a main shaft link assembly.

Background

A sewing machine is a machine that uses one or more sewing threads to form one or more stitches in a material to be sewn, thereby interweaving or stitching one or more layers of material. The sewing machine can sew fabrics such as cotton, hemp, silk, wool, artificial fiber and the like and products such as leather, plastic, paper and the like, and the sewed stitches are neat, beautiful, flat and firm, the sewing speed is high, and the use is simple and convenient. And derives the artistic forms of hand-push embroidery, computer embroidery, etc. The sewing machine is composed of four parts of machine head, machine base, transmission and accessories. The head is an essential part of the sewing machine. The sewing machine consists of four mechanisms of material needling, thread hooking, thread picking and feeding, auxiliary mechanisms of winding, material pressing, tooth falling and the like, and the motion of the mechanisms is reasonably matched and works circularly to sew up sewing materials. The machine base is divided into two forms of a bedplate and a machine box. The table of the table type machine base plays a role of supporting the machine head and is used as a working table during sewing operation. The bedplate has various styles, such as one-bucket or multi-bucket folding type, cabinet type, writing desk type and the like. The machine box of the machine box type machine base plays a role of supporting and storing the machine head, so that the sewing machine is convenient to carry and store.

The transmission part of the sewing machine is composed of a frame, a hand crank or a motor and the like. The frame is the pillar of the machine, supporting the bedplate and the footboard. When the device is used, an operator steps on the pedal plate, the belt pulley is driven to rotate through the crank, and the machine head is driven to rotate through the belt. Most hand-operated devices or motors are directly mounted on the handpiece.

The accessories of the sewing machine comprise a needle, a bobbin, a screwdriver, an oil can and the like.

At present, the existing sewing machine still has the defects in use, the sewing needle of the existing sewing machine is connected with the transmission rod through electric power to move the sewing needle pipe up and down so as to achieve the purpose of sewing cloth, but the traditional transmission rod structure is easy to cause the bending and breaking of the sewing needle due to the structural defect, the sewing effect is poor due to the reduction of the sewing force, the sewing efficiency is reduced, and the using effect of the product is reduced.
