Rotational force driving assembly process cartridge

A process cartridge comprising:

• a cartridge;
• a rotational force driving assembly used for receiving rotational driving force from a rotational force driving head inside an electrophotographic image forming device, said rotational force driving assembly comprising:
• a hub,
• a rotational force receiving component for driving the hub to rotate,
• a plate piece provided at one end of the hub,
• wherein the plate piece enables the rotational force receiving component to move between a first position in which the rotational force receiving component extends out and the axis of the rotational force receiving component is coaxial with the axis of the hub,
• and a second position in which the rotational force receiving component retracts and the axis of said rotational force receiving component is parallel to and offset from the axis of the hub.

A rotational force driving assembly used for receiving rotational driving force from a driving head inside an electrophotographic image forming device, said rotational force driving assembly comprising:

• a transmitting component,
• a coupling component for driving the transmitting component to rotate,
• a pressing component for controlling the coupling component to extend or retract along the axial direction of the transmitting component,
• a plate provided at one end of the transmitting component,
• wherein the pressing component retracts by being pressed and controls the coupling component to retract, the retracting direction of the pressing component and the retracting direction of the coupling component is the same direction and is parallel to each other,
• wherein when the coupling component disengages from the driving head, the plate enables the coupling component to retract along the axial direction of the transmitting component, the axis of the coupling component is not coaxial with the axis of transmitting component or the axis of the coupling component is parallel to and offset from the axis of transmitting component.
