Abstract
In some embodiments, a crossbow crank comprises a housing and a shaft rotatable with respect to the housing. A one-way mechanism is arranged to prevent rotation of the shaft in a first rotational direction, but allow rotation in a second direction. A release mechanism is arranged to disengage the one-way mechanism from the shaft. The release mechanism has a first position and a second position, wherein the release mechanism moves along a length of the shaft between the first position and the second position.
