Patent ID: 6877937

Claim:
A reversible drill/driver tool for use with a powered drill having a chuck, comprising: an elongated socket including a cylindrical part, and a bifurcated part having two spaced apart mounting plates extending axially from said cylindrical part to define a tool-receiving space between said mounting plates; a drive shank connected securely to said cylindrical part; a reversible two-ended tool assembly including first and second driving bits, and an elongated rod having a first end section detachably connected to said first driving bit, and a second end section opposite to said first end section and detachably connected to said second driving bit, said elongated rod being mounted rotatably on said mounting plates of said bifurcated part of said elongated socket and being rotatable between a first position, where said first end section of said elongated rod and said first driving bit are received and extend axially in said tool-receiving space and where said second end section of said elongated rod and said second driving bit extend axially and outwardly from said tool-receiving space, and a second position, where said second end section of said elongated rod and said second driving bit are received and extend axially in said tool-receiving space and where said first end section of said elongated rod and said first driving bit extend axially and outwardly from said tool-receiving space; a positioning unit including a sleeve mounted slidably on said elongated socket, a first engaging member formed on said sleeve, and a pair of second engaging members formed on and extending respectively and oppositely from said first and second end sections of said elongated rod in an axial direction relative to said cylindrical part, said sleeve being slidable between a locked position, where said first engaging member engages one of said second engaging members which is formed on the respective one of said first and second end sections which is disposed in said tool-receiving space so as to prevent rotation of said elongated rod and so as to dispose said elongated rod at a respective one of said first and second positions, and an unlocked position, where said first engaging member disengages from said one of said second engaging members so as to permit rotation of said elongated rod relative to said elongated socket; and an urging member abutting against said sleeve so as to urge said sleeve to move to said locked position.
