Description

Sewing machine capable of lifting needle head assembly Technical Field The utility model relates to the technical field of sewing machines, in particular to a sewing machine capable of lifting a needle head assembly. Background The sewing machine is a machine which uses sewing threads to form stitches on the materials to interweave or stitch one or more layers of the materials, and when the sewing machine is used for sewing, the actions of feeding cloth, cutting threads and lifting presser feet are often needed, and the corresponding sewing machine is provided with a cloth feeding mechanism, a thread cutting mechanism and a presser foot lifting mechanism. In the prior art, because the limitation of the structure and the transmission mode of the sewing machine is that the feed and the lifting teeth are performed back and forth through the tooth frame, the movement of the tooth frame in the two directions of the feed and the lifting teeth is easy to generate a matching error, and different acting forces are needed to control the tooth frame to feed and lift the feed, so that the convenience and the efficiency of sewing are improved, and the design of the sewing machine for lifting the needle head assembly is needed to solve the problems.
