While the ink enters the ink cartridge through the ink outlet holes, a reaction force is applied to the hollow stirring rods. The hollow stirring rods apply force to the hollow sliding ring, so that the hollow sliding ring moves along the opening direction of the spiral through groove and moves along the axial direction of the guide rod at the same time, realizing the stirring and mixing of the ink in the ink cartridge. Then, the commutation unit changes the blocking state of the hole blocking unit on the ink outlet holes, and the hollow stirring rods move in the reverse direction, and so on, realizing the reciprocating cycle stirring of the ink in the ink cartridge; the designed ink anti-solidification device in the ink cartridge provides an installation basis for the connecting block and the hollow sliding ring through the guide rod, is convenient for sending ink into the telescopic ink delivery pipe through the ink delivery unit, and then replenishes ink into the ink cartridge.

With the cooperation of a rotating sleeve 71 and a magnetic block 72, ink outlet holes 41 on a plurality of hollow stirring rods 4 that are connected to the ink cartridge face the same rotation direction, such as a counterclockwise direction. While the ink enters the ink cartridge through the ink outlet holes 41, a reaction force is applied to the hollow stirring rod 4. The hollow stirring rod 4 applies a force to the hollow sliding ring 3, so that the hollow sliding ring 3 moves along the opening direction of the spiral through groove 11 and along the guide rod 1. The axial movement is used to stir and mix the ink in the ink cartridge until the hollow stirring rod 4 drives the rotating sleeve 71 to move to the elastic paddle 81 close to one side of the ink cartridge, and the elastic paddle 81 abuts against the force bar 82 on the outer periphery of the rotating sleeve 71, so that the rotating sleeve 71 overcomes the magnetic attraction of the magnetic block 72, and the rotating sleeve 71 and the hollow stirring rod 4 rotate relative to each other, so that the corresponding relationship between the give way groove 711 and the ink outlet hole 41 is swapped. At this time, the direction of the ink outlet hole 41 connected to the ink cartridge is completely opposite to that before, and the hollow stirring rod 4 realizes reverse movement. When it moves to the elastic paddle 81 at the other end of the ink cartridge, the hollow stirring rod 4 moves in the opposite direction again, and so on and so forth, to realize reciprocating circulation stirring of the ink in the ink cartridge.
