ABSTRACT:
A rachet-type hand tool having a sleeve-like guide freewheelingly mounted about a main body portion of the tool. A main shaft is rotatably mounted within the interior of the main body. An upper end of the shaft is secured to a three-way rachet mechanism. An operating rod/socket coupler releasably couples tool implements such as screwdriver heads, hex heads and the like to the operating rod. A torque extension handle is releasably mounted to the upper end of the main body and is provided with short and long lever arms selectable for gripping by the user to obtain the desired torque. Finger holes are provided in the torque extension handle for rapid rotation of the tool for insertion or removal of a screw, bolt or the like when only very light friction is encountered. An opposite arm of the torque extension handle is easily removed and can be replaced by another torque extension arm. The freely rotatable guide sleeve facilitates positioning, holding and guiding of the tool while either low speed or high speed torque is applied.
