When the head needs to be removed, the moving bar is pulled upward, thereby driving the connecting bar to move upward, thereby driving the latch upward. Since the third moving groove is an oblique groove, the limit block will move toward a position close to the spring, thereby causing the limit block to disengage from the limit groove. At this time, the head can be removed. When the head needs to be installed, the limit block is aligned with the first mounting groove, and the connecting piece is pressed downward, thereby squeezing the inclined surface of the limit block against the edge of the first mounting groove, thereby causing the head to be installed. The limit block moves toward the position close to the spring, the spring contracts, and the connecting piece extends into the first installation groove, and then the spring rebounds, and the limit block enters the limit groove. At this time, the machine head is installed. Compared with the existing machine head structure, the connection between the machine head and the bridge is usually connected by bolts. When the machine head fails to work for a long time and needs maintenance, the staff needs to waste a lot of time on removing the bolts, which is obviously not conducive to the maintenance work and wastes the staff's time. The machine head structure of the knitting machine can make the disassembly and assembly between the machine head and the bridge faster, saving the staff's time and facilitating the maintenance work.
