Abstract
A power tool for tensioning hose clamps of the type wherein one end portion of a strap overlies the other end portion and has a laterally extending tip which can break away or bend in response to the application of a pull sufficient to effect satisfactory tensioning of the looped central portion of the strap around a hose or the like. The tool has a barrel with an inlet receiving the one end portion so that the tip can be engaged by the shoulder of an entraining element mounted at the front end of a retractible piston rod. The tensioning element is reciprocable in and relative to a bearing which is reciprocable in the barrel by interposition of friction reducing rolling elements. When the piston rod is retracted, the shoulder of the tensioning element moves against the tip of the one end portion of the strap and exerts a pull upon the tip while moving with the bearing so that the force which is needed to bend or break the tip at least approximates the maximum force that is necessary to retract the piston rod. Upon flexing or breakage of the tip, the bearing and the tensioning element reassume predetermined starting positions in which they are ready for the next tensioning operation.
