Background
In the prior art, the transmission mechanism comprises an input gear, an output gear and a transmission mechanism arranged between the input gear and the output gear, and the transmission mechanism is formed by connecting a plurality of transmission gears in a transmission way. In the power transmission stage, power is input from an input gear and is transmitted to an output gear through a transmission gear, and the output gear outputs power. Wherein, a gear stage is formed between any adjacent gears, and the more the number of gears is arranged, the more the gear stage is formed.

In a specific operation process, the external power source drives the input gear 120 to rotate in a forward and reverse direction, and the two first gear assemblies 140 are in transmission connection with the input gear 120, so that the input gear 120 drives the two independent first gear assemblies 140 to rotate simultaneously. And, each of the first gear assemblies 140 is connected to the output gear 130, so that the two first gear assemblies 140 simultaneously drive the output gear 130 to rotate, and the output gear 130 outputs power when rotating.
Compared with the prior art that one path of first gear assembly 140 is adopted to complete power transmission, the power transmission from the input gear 120 to the output gear 130 is completed by adopting two paths or more paths of first gear assemblies 140, gears at the initial positions of the first gear assemblies 140 are tightly attached to the input gear 120, gears at the tail end positions of the first gear assemblies 140 are tightly attached to the output gear 130, and therefore, the power input by the input gear 120 is transmitted to the output gear 130 step by the first gear assemblies 140 in a coordinated manner.
