[0033] Specifically, the rotating block 3 drives the baffle 4 to rotate, and the ink inside moves accordingly. When the baffle 4 reaches the limit plate 23, the sealing plate 6 is resisted, and the rotating cover 5 moves with the baffle to discharge the ink into the ink outlet box 8. After exceeding the limit plate 23, the torsion spring 7 resets the sealing plate 6, the hollow plate 9 rotates, and the slider 10 opens the ink outlet box 8 along the slide groove 11 for user operation. The ink cartridge 1 is separated from the ink outlet box 8, and backflow can be prevented without a one-way valve.
[0034] Reference Figure 1 , Figure 2 and Figure 3 The positioning mechanism 2 includes a positioning frame 201, which is fixedly connected to the top right side of the ink cartridge 1. The outer side of the positioning frame 201 is rotatably connected to a rotating plate 202. The front and rear sides of the outer wall of the rotating plate 202 are fixedly connected to a plug-in rod 203. The front and rear sides of the outer wall of the ink cartridge 1 are fixedly connected to a mounting block 204. The inner side of the mounting block 204 is slidably connected to a U-shaped frame 205. The upper and lower sides of the outer wall of the U-shaped frame 205 are provided with reserved holes 206. The outer side of the plug-in rod 203 penetrates the mounting block 204 and engages with the reserved hole 206.
[0035] Specifically, the U-shaped frame 205 is slid up and down along the mounting block 204 to adjust the positions of the multiple reserved holes 206. The positioning frame 201 rotates the rotating plate 202 and the plug-in rod 203. The plug-in rod 203 passes through the mounting block 204 and engages with the reserved hole 206.

[0037] Specifically, the knob 16 can be used to drive the rotating block 3 to rotate, the bracket 21 and the rubber pad 22 can be used to fix the device, and the positioning block 17 and the positioning hole 18 thereon can be used to hang the device for storage.
[0038] Reference Figure 2 , Figure 3 and Figure 4 The left side of the hollow plate 9 is fixedly connected with a handle 19, and the outer side of the handle 19 is fixedly connected with a sheath 20; the left side of the ink cartridge 1 is rotatably connected with a connecting plate 12, and the top of the hollow plate 9 is fixedly connected with a connecting block 13, and the connecting block 13 is engaged with the connecting plate 12; a reserved groove 14 is provided at the bottom of the outer wall of the ink cartridge 1, and an observation window 15 is fixedly connected to the inner side of the reserved groove 14;
[0039] Specifically, the handle 19 can facilitate the carrying and moving of the device, and the sheath 20 thereon can improve the comfort of holding the handle 19. By rotating the connecting plate 12 to engage it with the connecting block 13, the position of the hollow plate 9 can be fixed to prevent it from being accidentally opened. Through the observation window 15 in the reserved groove 14, the ink storage amount in the device can be observed in real time to facilitate timely ink addition.
[0040] Working principle: before using the device, first rotate the rotating block 3 to drive the baffle 4 on it to rotate, so as to drive the ink inside to move. When the baffle 4 moves to the limit plate 23, the sealing plate 6 will be resisted by the limit plate 23, and move along the baffle by rotating the cover 5 to discharge the ink into the ink outlet box 8. When the limit plate 23 is rotated, the elastic potential energy of the torsion spring 7 will reset the sealing plate 6. Then, rotating the hollow plate 9 can drive the slider 10 to slide along the slide groove 11 to open the ink outlet box 8, which is convenient for users to use. By separating the ink box 1 from the ink outlet box 8, the anti-backflow effect can be achieved without using a one-way valve.
[0041] By sliding the U-shaped frame 205 up and down along the mounting block 204, the positions of the plurality of reserved holes 206 can be adjusted, and the rotating plate 202 and the plug-in rod 203 thereon are rotated along the positioning frame 201 so that the plug-in rod 203 passes through the mounting block 204 and engages with the reserved hole 206. The angle of the ink cartridge 1 can be adjusted and controlled to facilitate pouring and discharging of ink.
