Power tool with illumination device

摘要

A power tool, such as a screwdriver is described, which comprises an illumination device (18) for illuminating a work region. The illumination device is disposed on the front face of the screwdriver's gearbox to achieve this aim. Also provided is an extension piece (22) which is attachable to the front of the screwdriver. A central prop-shaft (24) engages with the spindle (16) when the extension piece is attached to the screwdriver. A waveguide (40) is provided to guide light emitted by the illumination device(s) so as to provide sufficient illumination of a work region when the extension piece is attached to the screwdriver. The light is emitted from the waveguide in a direction which is generally axial to the axis of rotation of the extension's drive output (28). The screwdriver is operable in two modes, with or without the extension and sufficient illumination of a work region is provided in both modes.
