BACKGROUND A process cartridge is a cartridge capable of being detachably installed in a host machine of ait imaging device. As a whole unit the cartridge includes an electrophotographic photosensitive component and at least one of the processors such as a charger, a developer, a cleaner and the like. Maintenance of the equipment is facilitated as the process cartridge is detachably installed relative to the host machine of the equipment. An electrophotographic imaging device employing an electrophotographic imaging manner operates in such a manner that the electrophotographic photosensitive component uniformly charged by a charger is selectively exposed by the light passing through the imaging device to form an electrostatic latent image, which, is developed into a toner image through a developer toner, and the formed toner image is transferred onto a record medium by a transfer device so as to form an image on the record medium.
Generally, a power receiving device is arranged on the photosersn've component of the process cartridge, and is engaged with a machine driving device in the imaging device to drive the rotary motion of the photosensitive component and the operation of the whole process cartridge.

When the process cartridge is installed at the machine falling position 103, the jacking block 32 applies the pre-jacking force F to the process cartridge through the first elastic element 31, so that the process cartridge tends to rotate in a clockwise manner, and thus the compression bar 33 forcedly pushes the upper installation rail 1.GL at this moment, the compression bar 33 is in a pressed state all the time and the power recei ving portion 24 is in a retraction state. When the customer closes the door of the imaging device, die door applies an extrusion force FI to the stressed portion 12 of the process cartridge, the process cartridge overcomes the pre-jaeking fores F of the first elastic element 31 to rotate in an anticlockwise manner relative to the jacking block 32, the jacking block 32 rotates to die second stopper portion 11 relative to the process cartridge, so that the compression bar 33 of the process cartridge releases the forced pushing on the upper installation rail 101, and is not subject to the forced pushing of the upper installation rail 101. Under the action of die restoring force F3 oi the second elastic element 22, a power receiving port 24e in die power receiving portion 24 extends axially to be engaged with the machine driving head 100, so as to drive the process cartridge to operate normally.
The process cartridge needs to be detached from the imaging device after its operation is completed, the door of the imaging device is opened to stop applying the extrusion force FI to the stressed portion 12 by the door, at this moment, under the action of die pre-jacklng force F of the first elastic element 31, the process cartridge is jacked by the jacking block 32 to rotate in a clockwise manner to drive the compression bar 33 to press the upper installation rail 101, so that the compression bar 33 rotates in an anticlockwise manner relative to the upper installation rail 101, at this moment, the push forcing slant 33e of the compression bar 33 applies a forced thrust F2 to forcedly push the pushed slant 21a of the dri ving portion 27, the forced thrust F2 overcomes tire restoring force F3 of the second elastic element so that the driving portion 27 drives the power receiving portion 24 to retract inwards along the axial direction Y, at this moment, the power receiving portion 24 is in a retraction, state, the power receiving portion 24e on the power receiving portion 24 Is disengaged from the machine driving head 100, and the process cartridge can be taken ont without Interference,
In the present utility model, since the driving portion 27 and the power receiving portion 24 are separately arranged, when the photosensitive drum driving component 20 and the compression bar 33 carry out forced pushing, the rotation of the power receiving portion 24 will not be influenced by the forced pushing action, thus effectively avoiding integrated arrangement of the driving portion and the power receiving portion. When the power receiving portion 24 rotates, the compression bar and tire driving portion carry ont forced pushing to generate faction with the rotating power receiving portion, which influences power transmission.
According to the process cartridge of the present utility model, the jacking block and the first elastic element cm be arranged to jack up the process cartridge, therefore, when the process cartridge Is not in use, the compression bar is pressed by the upper installation rail all the time and the power receiving portion is in a retraction state, and no interference will occur; when the process cartridge is in use, by virtue of the extension cooperation of the stressed portion on the process cartridge and the door, the extrusion force changes the jacked~up state of the process cartridge, the compression bar releases the pressing of the Installation rail, and the power receiving portion 24 extends to be engaged with the machine driving head. By adopting the technical solution, the extension and retraction of the power receiving portion 24 trigger the extrusion from the door of the imaging device, and the trigger action can be realized by virtue of an essential action that the customer opens/closes the door of a machine when using the process cartridge, without additional operation of the customer, which conforms to the use habit of the customer. Moreover, the control is accurate and foe process cartridge generates no interference in the installation and detachment process.
