Abstract: The present disclosure discloses a crank quick-connection structure. The crank quick-connection structure is used for connecting a crank with a main shaft, and includes an adapter and a connecting assembly. The adapter is connected to the main shaft, one end of the crank is provided with a cooperating cavity extending in a thickness direction thereof, and the adapter penetrates the cooperating cavity from one end of the cooperating cavity. The connecting assembly is connected to the adapter, and the connecting assembly has a locking position and a releasing position. In the locking position, the crank cooperates with the connecting assembly so that the cooperating cavity and the adapter are locked and connected; and in the releasing position, the crank is disengaged from the connecting assembly so that the crank can be disengaged from the adapter in an axial direction of the adapter.
