[0014] Further, the fixed frame and the rubber ring sleeve are designed as arc surfaces on the side facing the powder adding sleeve powder inlet.

[0015] The technical scheme is achieved by reducing the blocking effect of the fixed frame and the rubber ring sleeve on the ink powder.

[0016] Further, the powder passing rod on both sides of the rubber ring sleeve is connected by a blocking piece, and the outer diameter of the blocking piece is larger than the hole diameter of the center hole of the rubber ring sleeve, which is used for hiding and completely extending the powder passing rod.

[0017] The technical scheme is achieved by determining the completely extended position and the completely hidden position of the powder passing rod.

[0018] Further, the powder passing rod is connected by an extension rod on the side of the powder passing rod, and the extension rod is distributed along the surface of the powder passing rod in a staggered manner.

[0019] The technical scheme is achieved by improving the dredging effect of the ink powder.

[0020] The technical effects and advantages of the utility model are as follows:

[0021] The utility model adopts the small-aperture deformable rubber ring sleeve and the large-aperture powder passing rod to limit the extrusion and friction, so that the length of the powder passing rod in the powder adding sleeve can be adjusted, and the extended powder passing rod is used to pass the ink powder at the bottle neck.

[0022] Compared with the prior art, the powder passing rod does not continuously extrude the sealing plug in the non-use state of the device, so that the sealing plug is less likely to be damaged and accidentally fall off from the powder adding sleeve, and powder leakage is prevented.
