Background In the prior art, a small motor is widely used in various electric devices, and a transmission structure for transmitting rotation power generated by a rotor to an output shaft is generally arranged in the small motor. The transmission structure generally includes one or more transmission gears for effecting speed and torque conversion and transmission. In order to reduce noise generated in the running process and reduce the overall weight, the existing transmission gears are mostly made of plastic materials. However, since the small motor itself is compact in structure, the volume of the transmission gear is small, and although the plastic gear has good vibration and noise reduction performance, the strength is relatively low, and deformation and even fracture are easy to occur when bearing large torque.
