Screwdriver with an indicator bulb

The indicator bulb screwdriver consists of a screwdriver, an indicator bulb base, a LED bulb and a battery,

• A screwdriver, with the interior part of its handle holds a fixation base. In the bottom of the fixation base is a semi-circular ring;
• An indicator bulb base, which matches the fixation base, is made from plastic. In front and below the bulb base is a longitudinal slot. The bottom of the longitudinal slot is connected to a semi-circular hole. Inside the slot and the hole is a slightly bigger rectangular slot cut through by the longitudinal slot in a transverse way. In the middle of the rectangular slot is an embedded slot that is connected to an arc-shaped battery container behind. Right above the battery container is an arc-shaped press button found on a prominence of the surface of the bulb base;
• A LED bulb, of which a diode cable passes through an embedded slot and be connected to the positive and negative electrodes of the battery in the battery container, is inserted into the semi-circular hole by passing through the longitudinal slot;
• A battery;
• The LED diode cable is pressed by pressing the arc-shaped press button, so that power is supplied by the battery, and thus the area in front of the screwdriver is illuminated by a parallel light ray and working with poorly illuminated screw holes can be efficient.
