Fuser driving device for image forming device

A fuser driving device, comprising:

• a front frame and a rear frame, wherein the front frame and the rear frame are fixedly connected to each other;
• a gear, wherein two ends of the gear are respectively mounted to the front frame and the rear frame through a bearing;
• a driving arm mounted in the gear, wherein the driving arm is movable axially along the gear to enter into or withdraw from a fuser, and when the driving arm enters into the fuser, the driving arm is driven to rotate through the gear, to drive a fusing roller of the fuser to rotate;
• and
• a withdrawing device comprising a pulling member and an operating member, wherein one end of the pulling member is connected to the driving arm and the other end of the pulling member is connected to the operating member, and the pulling member is moved by operating the operating member, to pull the driving arm to withdraw from the fuser into the gear;
• wherein a spring is arranged between the driving arm and the gear, and the spring is compressed when the pulling member pulls the driving arm to withdraw into the gear;
• wherein the pulling member comprises a first spherical component, a second spherical component and a flexible connector, and wherein the first spherical component is connected to the driving arm and the second spherical component is connected to the operating member, and the flexible connector passes through the spring and connects the first spherical component and the second spherical component;
• wherein the operating member comprises a connecting part and a handle part, one end of the connecting part is connected to the pulling member, and the other end of the connecting part is connected to the handle part;
• and
• wherein the operating member is connected to the rear frame through a sliding shaft, and the connecting part is driven to move the pulling member by moving the handle part along the sliding shaft, to pull the driving arm to withdraw into the gear.
