1. A flex head tool comprising:
a first body and a second body pivotally coupled to the first body, wherein the first body defines a first orifice and a second orifice cooperatively receiving a retaining device which is adapted to position the first body with respect to the second body at various angular positions, wherein the retaining device includes a retainer movably disposed in the first orifice and an actuator movably disposed in the second orifice, wherein the second body has a first engaging structure and the retainer has a second engaging structure selectively engaging with different sections of the first engaging structure such that the first body is fixed with respect to the second body at different angular positions, wherein the actuator abuts the retainer and is movable between a first position in which the first and the second engaging structure are engaged with each other and a second position in which the first and the second engaging structures are disengaged from each other thereby allowing the first and the second bodies move relative to each other, wherein the retainer and the actuator respectively have a first interacting structure and a second interacting structure abutting each other, wherein the second interacting structure is at an end of the actuator and has a first and a second position at which the first interacting structure respectively abuts when the actuator is at the first position and the second position, and wherein the first and the second positions of the second interacting structure are at different distances from an end of the actuator;
wherein one of the first and the second interacting structures includes a rib protruding therefrom and the other of the first and the second interacting structures forms at least one projection respectively, and wherein the rib protrudes from a surface of one of the first and the second interacting structures on which the at least one projection of the other of the first and the second interacting structures abuts; and
wherein the at least one projection of the other of the first and the second interacting structures includes two projections disposed in a spaced relationship, wherein the two projections delimit a cavity therebetween, and wherein the two projections of the other of the first and the second interacting structures abut the surface of one of the first and the second interacting structures, and wherein when the actuator is in the first position, the rib is in the cavity and held between opposite sides of the two projections, and wherein when the actuator is in the second position, the rib is in the cavity and held between opposite sides of the two projections.
