Abstract

An improved driver structure including a driver shell, a tool portion for mounting a tool connecting portion disposed on said driver shell, and a lighting portion with a light source. The tool portion accommodates a swivel shaft therein, the swivel shaft accommodating more than one drive bit. By turning the swivel shaft, the drive bit may be turned to an opening on the tool portion so that the drive bit may be pushed out via the opening and then fitted onto the tool connecting portion. The light source of the lighting portion provides light for working at night.

Claims

1. An improved driver structure, comprising a driver shell comprising a tool portion for mounting a tool connecting portion, and a lighting portion with a light source, wherein

said tool portion accommodates therein an action groove for accommodating a swivel shaft, a shaft post for pivotally connecting said swivel shaft being disposed in said groove, said action groove being inserted through a sleeve of said swivel shaft, said sleeve having thereon a plurality of partition plates which are connected to a base disk below, a drive bit being disposed between two adjacent partition plates, each of said partition plates being provided with a retain strip at either side for securing a drive bit, and one of said partition plates being covered by a cover plate, a swivel plate being disposed below said base disk, said swivel plate having a through hole communicating with said sleeve such that a screw may pass through said through hole to engage with the inner threads of said shaft post to enable said swivel shaft to be pivotally mounted on said shaft post, said through hole being closed by a cap, and said tool portion being provided with an opening with a curved plane extending from a front end therefrom;

and

said lighting portion has a handle portion at a lateral rim thereof, said handle portion being provided a securing sleeve means for pivotally connecting a retainer;

whereby

by means of turning said swivel shaft, the drive bit may be turned to said opening and pushed along said curved plane extending from said front end of said opening; and

said light source of said lighting portion supported on said tool portion provides a lighting function.

2. An improved driver structure as claimed in claim 1, wherein a turning mechanism is disposed below said tool connecting portion, a switch for controlling said turning mechanism being disposed on said turning mechanism, said switch extending through a recessed hole at an upper rim of said tool portion.
