Inside it is provided with the rotatable elements such as photosensitive drums 101, powder feeding roller 102, developer roll 105, puddle support.In 101 one end of photosensitive drums
Driving connector 103 is provided with, driving connector 103 can coordinate with the driving head of image forming apparatus, be driven so as to receive rotation
Power rotates photosensitive drums 101.Due to not having drive connection between the photosensitive drums 101 of the handle box and other rotating elements,
Therefore in another driving connector 104 of the one end of powder feeding roller 102 setting, the driving connector 104 and image forming apparatus
Another driving head matches, and rotates powder feeding roller 102 so as to receive rotary driving force.The end of powder feeding roller 102 is additionally provided with biography
Moving gear forms drive connection by the rotating elements such as transmission gear and puddle support, developer roll, thus by image forming apparatus
Rotary driving force passes to these rotating elements.Since handle box tool is there are two driving connector, double drive when tilting installation
Connector is difficult to be directed at installation with the driving head on image forming apparatus, and inconvenience is brought to user.
Utility model content
The purpose of this utility model is to provide a kind of handle box being easily installed.
To achieve these goals, the utility model takes following technical solution：
A kind of handle box including housing, is provided with photosensitive drums, developer roll in the housing；It is provided in the photosensitive drums
Transmission gear, the transmission gear are meshed with the developing roller gear being set on the developer roll, the tooth of the transmission gear
Number is 56~58.
Further, the gearratio of the transmission gear and the developing roller gear is 1.8~2.
Further, the number of teeth of the transmission gear is 57.
Further, the gearratio of the transmission gear and the developing roller gear is 1.9.
Further, the transmission gear is set to one end that the photosensitive drums are provided with driving connector.
Further, an at least tension spring is provided between the photosensitive drums installing plate of handle box and developer roll installing plate,
The tension spring is located at the side of photosensitive drums, and one end of the tension spring is connected with photosensitive drums installing plate, and the other end is installed with developer roll
Plate is connected.
Further, the driving connector for being set to photosensitive drums end is fixedly connected on the end of the photosensitive drums.
Further, the handle box can be packed into when being installed in image forming apparatus in a manner of first tilting and ajusting afterwards
Image forming apparatus.
By above technical scheme it is found that the utility model is meshed by increasing by one in photosensitive drums with developing roller gear
Transmission gear, send rotary driving force to developing roller gear by transmission gear, and pass through developing roller gear by rotate drive
Power continues to pass to other rotating elements such as powder feeding roller, so as to remove the driving connector being set in powder feeding roller, by two
A driving connector is reduced to a driving connector, and solving handle box, double drive connector is difficult to and driving head when mounted
The problem of alignment installation, while the optimization design number of teeth of transmission gear and the gearratio with developing roller gear, it is ensured that
Print speed and print quality.
