ABSTRACT:
A screw driver includes a rod slidably and rotatably received in a hand grip and having one end for engaging with a tool bit. A handle has one end pivotally coupled to the rod for allowing the handle to rotate to a position perpendicular to the rod and for allowing the handle to apply a great torque to the rod and for allowing the tool bit and the rod to be easily operated. The handle includes a pole pivotally coupled to the rod and a sleeve engaged on the pole. The sleeve has an annular flange for engaging with an enlarged head of the pole and for limiting a relative movement between the pole and the sleeve.
