A wrench includes a driving cartridge having one end rotatably secured to a handle at a shaft and rotatable in a horizontal plane parallel to that of the handle. A pawl is slidably disposed between the driving cartridge and the handle and is selectively coupled to the driving cartridge for allowing the driving cartridge to be adjusted relative to the handle at any selected angular position. A barrel is rotatably disposed between the driving cartridge and the handle for receiving the pawl and coupled to the pawl for moving the pawl toward and away from the cartridge.
