As a preference, a connecting piece is disposed between the connecting member and one side of the photosensitive drum, and the connecting piece is provided with anti-slip teeth.

As a preferred item, the left and right sides of the powder container housing are provided with a spacer pull ring, wherein the isolation pull ring is provided with an isolating insert for separating the photosensitive drum and the charging roller.

As a preferred item, the connecting piece is provided with a jack, and the connecting piece is provided with a plunger at a position corresponding to the jack.

As a preference, the connecting shaft includes a shaft body and a card joint.

As a preference, the outer edge of the connector is distributed with support ribs.

As a preference, the charging roller is provided with short shaft pins at both ends thereof.

As a preference, the charging roller has a long shaft pin built therein.

As a preference, the charging roller has a long steel shaft built therein.

The utility model has the beneficial effects that the toner cartridge structure is troublesome and wastes materials for the long steel shaft of the original drum core, and replaces the original length by reasonable structural improvement, especially through the design of the short connecting shaft fitting connector. The steel shaft method not only improves the installation efficiency, but also saves material.

In addition, it should be noted that the words "front", "back", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, the words "inside" and " "Outer" refers to the direction toward or away from the geometric center of a particular component, and the skilled artisan is simple in the above-mentioned directions, and does not require creative adjustments, and should not be construed as being outside the scope of protection of the present application. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the scope of the invention. To avoid obscuring the objects of the present invention, well-known methods, procedures, components, and circuits have not been described in detail since they are readily understood. 1 and 2, a cartridge roller shaft mounting structure includes a powder cartridge housing 1 in which a photosensitive drum 2 and a charging roller 3 are built, and one side of the powder cartridge housing 1 is disposed. There is a fixing plate 11 on the other side of which is provided with a detachable detachable plate 4, and the other side of the photosensitive drum 2 is provided with a transmission gear 5, one of the photosensitive drums 2 The connecting shaft 6 and the connecting member 7 are provided on the side, wherein the short shaft replaces the long steel shaft of the past, and the connecting member 7 serves as a connecting member between the photosensitive drum 2 and the connecting shaft 6. At the time of installation, it is only necessary to connect the connecting shaft 6 to the mounting position of the fixing plate 11 of the powder container housing 1, and to mount the connecting shaft 6, the photosensitive drum 2, and then the transmission gear 5 of the photosensitive drum 2 to the disassembling plate 4 After the position, the disassembly plate 4 is attached, thus completing the installation of the photosensitive drum 2. The short ends of the charging roller 3 are provided with short shaft pins 31, and the disassembly and assembly plate 4 can improve the installation efficiency.

In another embodiment, reference is made to a drum roller shaft mounting structure of Figures 1 and 2, wherein the "embodiment" referred to herein refers to a particular feature, structure, or characteristic that can be included in at least one implementation of the present application. The appearances of the embodiments in the various embodiments are not all referring to the same embodiment, and are not a single or alternative embodiment that is mutually exclusive. The embodiment includes a powder cartridge housing 1 having a photosensitive drum 2 and a charging roller 3 built therein, and a left side of the powder container housing 1 is provided with a fixing plate 11 for the powder cartridge housing 1 A removable detachable plate 4 is disposed on the right side, and a transmission gear 5 is disposed on the right side of the photosensitive drum 2, and a connecting shaft 6 and a connecting member 7 are disposed on the left side of the photosensitive drum 2, and the connecting member A connecting piece 8 is disposed between the left side of the photosensitive drum 2, and the connecting piece 8 is provided with anti-slip teeth 81.
