It should be noted that in some other embodiments of the present invention, the other end of the rotating shaft 31 is supported by the limiting clamping plate 33, so as to prevent the rotating shaft 31 from loosening due to vibration.
Referring to fig. 1 to 3, the first limit teeth 32 are helical gears. The first limit teeth 32 engage with a helical gear on the printer drive mechanism. When the helical gear on the printer driving mechanism drives the first limit tooth 32 to rotate, a force is applied to the first limit tooth 32 to make the developing cartridge housing 10 approach the output mechanism in the printer.
It is worth explaining, in some embodiments of the present invention, a helical gear is provided on the output mechanism of the printer, the first limit tooth 32 provided on the developing cartridge housing 10 through the rotation shaft 31 is engaged with the helical gear on the output mechanism of the printer, the output mechanism through the printer drives the first limit tooth 32 to rotate, when the helical gear is engaged and rotated, the helical gear on the output mechanism of the printer applies an axial force to the first limit tooth 32 to make the developing cartridge housing 10 close to the output mechanism in the printer, and then the developing cartridge is pushed to lean on the printer, so as to prevent the developing cartridge from shaking.
Referring to fig. 4 and 5, the first limit tooth 32 is a spur gear, and a chamfer 321 is provided on a side of the first limit tooth 32 away from and/or near the output mechanism in the printer.

Referring to fig. 6, the first limit tooth 32 is a spur gear, and the axis of the rotating shaft 31 and the axis of the power receiving device 20 form a certain inclination angle.
It is worth to say that in some other embodiments of the present invention, the first limit tooth 32 through the slope is meshed with the straight gear on the output mechanism of the printer, so that the output mechanism of the printer applies an axial force to the first limit tooth 32 to make the developing cartridge housing 10 close to the output mechanism in the printer, and further the developing cartridge is pushed to the printer, and the shaking of the developing cartridge is prevented.
Referring to fig. 7, the side of the first limit tooth 32 remote from and/or adjacent to the output mechanism within the printer is provided with a second chamfer 322.
It is worth mentioning that in some other embodiments of the present invention, the existence of the second chamfer 322 can make the contact between the first limit tooth 32 and the spur gear on the output mechanism of the printer more stable, and avoid the vibration when the edge of the spur gear leads to the transmission.
Referring to fig. 1 to 3, the rotation shaft catching groove 331 is a half groove.
It can be understood that in some embodiments of the present invention, the rotation shaft slot 331 is a half slot, and the open slot of the rotation shaft slot 331 can facilitate the installation of the rotation shaft 31, thereby improving the installation efficiency of the rotation shaft 31 and further improving the production efficiency.
Referring to fig. 8 to 12, the stopper 30 includes: a hanging plate 34 and a second limit tooth 35. The hanging plate 34 is provided on the developing cartridge case 10. The hanging plate 34 is provided with a boss 341. The second stopper tooth 35 is rotatably provided on the boss 341. The second limit teeth 35 are helical gears. The second limit teeth 35 engage with a helical gear on the printer drive mechanism. When the helical gear on the printer driving mechanism drives the second limit tooth 35 to rotate, a force is applied to the second limit tooth 35 to make the developing cartridge housing 10 approach the output mechanism in the printer.
It is to be noted that, in another embodiment of the present invention, the second limit teeth 35 are fixed to the developing cartridge case 10 through the hanging plate 34. The second limit tooth 35 is engaged with a helical gear on an output mechanism of the printer, the output mechanism of the printer drives the second limit tooth 35 to rotate, and when the helical gear is engaged and rotated, the helical gear on the output mechanism of the printer applies an axial force to the second limit tooth 35 to enable the developing cartridge shell 10 to be close to the output mechanism in the printer, so that the developing cartridge is pushed to lean against the printer, and the shaking of the developing cartridge is prevented.
Referring to fig. 8 to 12, a slot 11 is formed in the developing cartridge housing 10, and the hanging plate 34 is inserted into the slot 11.
