ABSTRACT:
A screw driver includes a handle body, a shank and a light transmittable tubular member. The handle body has a front end portion with an end surface, and an illuminating unit mounted on the front end portion at the end surface. The handle body confines a compartment for receiving a cell unit therein. The handle body is provided with a switch unit that is adapted to connect electrically the cell unit to the illuminating unit. The shank is mounted on the handle body and extends from the end surface of the front end portion of the handle body. The tubular member has a rear end mounted detachably on the front end portion of the handle body around the end surface of the front end portion. The tubular member is capable of transmitting light generated from the illuminating unit to an exterior of the tubular member so as to achieve a signaling effect.
