ABSTRACT:
A ratchet screwdriver with illumination function, including a hollow main body in which an illumination device is disposed. A front end of the main body is fixedly connected with a transparent housing in which a ratchet sleeve is installed. By using a non-circular hole which has a shape for complementarily engaging with a ratchet seat, the ratchet seat is closer to the illumination device. Accordingly, when the light projected from the illumination device is focused at the front end of the sleeve, the base seat will not block the light and in use of the ratchet screwdriver, an illumination function can be achieved.
