Abstract
An extension bar with built-in light to be used in conjunction with a portable driving tool which has a coupling member. The extension bar comprises an elongated body having a socket for accommodating and receiving the coupling member of the driving tool at one end, and a coupling member at an opposite end. The socket is connected to an internal chamber of the elongated body, and the coupling member has a through bore which is also connected to the internal chamber. A built-in light assembly is installed inside the internal chamber of the elongated body and including a light bulb and a battery, the light bulb located adjacent to the through bore. The built-in light assembly has an electrical conducting and switching mechanism for establishing electrical connection between the battery and the light bulb and automatically switching on the light bulb when the extension bar is attached to the driving tool, and switching off the light bulb when the extension bar is detached from the driving tool. Therefore, when the extension bar is attached to the driving tool, it serves not only as an extension of the driving tool but also as a flashlight to illuminate the working area.
