Abstract: A ratchet driving mechanism includes a gear rotatably engaged in a housing. A pair of pawls are disposed in the opening and biased to engage with the gear by a U-shaped spring member. A pair of partitions are engaged with the gear and the spring member and the pawls for retaining the elements in place. A control ferrule is rotatably secured to the housing and includes a plate having an actuator extended between the pawls for acting on the pawls and for controlling the driving directions of the gear. The U-shaped spring member may be easily engaged into the housing.
