[0002] In the field of mechanical manufacturing and assembly, the pedal arm is a key component in the automobile or other mechanical equipment, and its assembly quality and efficiency directly affect the performance and production cost of the whole machine. In the traditional pedal arm assembly process, the assembly of the main shaft and the snap spring is an important link.
