Abstract
The power tool comprises a slit wrench having a pair of semi-cylindrical segments boltable to each other and defining a socket. At least one wrench segment has a laterally and outwardly-extending head defining a plurality of notches having ridges which are rounded and inclined to allow the application of a force thereto as by the rod of a hydraulic cylinder. A reaction-and-support structure serves as a mounting platform for the hydraulic cylinder. This structure also generates the required reaction forces. The rod of the hydraulic cylinder carries a drive pin which applies, during each power stroke of the cylinder, a drive force against consecutive notches, thereby rotating the threaded connector through a small angle during each power stroke of the cylinder.
