The connecting shaft 602 rotates through the first ball 603 and the limiting straight groove 604 to drive the embedded rod 402 to rotate. The embedded tube 402 rotates through the limiting bar 403 to drive the hollow connecting rod 401 to rotate. The hollow connecting rod 401 drives the stirring rod 406 to rotate inside the ink cartridge body 1 to mix the ink evenly, thereby preventing the ink stored in the ink cartridge body 1 from being in a stratified state when the printing press is running, thereby preventing the printed product from being dirty or ink running.
