ABSTRACT:
A precision screwdriver includes a hollow grip and a bottom cap screwed with a bottom end of the grip. An end face of the bottom cap is disposed with a central switch and a conducting member. A rotary cover is rotatably disposed at the end face of the bottom cap. A cell is received in the grip. A light shade is installed in a non-circular socket of front end of the grip. A bulb is disposed in the light shade. An engaging seat of a transparent sleeve is engaged in the non-circular socket. The front end of the sleeve is formed with a tool connecting section for engaging with a screwdriver head. The switch is received in the rotary cover, so that a user can push the end face of the rotary cover at the end of the grip with fingers or palm so as to rotate the precision screwdriver. Via the switch, the user is able to control the on/off of the bulb in the grip so as to provide an illumination for the work.
