Drill driver

A drill/driver including:

• a motor (6) for rotating a motor output shaft (14);
• a gearbox (16,18,20,22,24) coupled to the motor output shaft (14) and having a gearbox output shaft (26), the gearbox arranged to provide a change in rotational speed as between the motor output shaft (14) and the gearbox output shaft (26) and wherein the gearbox output shaft defines a first central output axis (A-A) of the drill/driver;
• a first offset output gear (30) driven by and coupled to the gearbox output shaft (26), wherein the first offset output gear is radially offset from the first central output axis (A-A) and is freely rotatable thereabout;
• the first offset output gear itself defining a second axis (B-B), which second axis is offset from, parallel to and rotatable about the first central output axis (A-A);
• a second offset output gear (52) driven by and coupled to the first offset gear (30), wherein the second offset output gear is radially offset from the second axis (B-B) defined by the first output gear (30) and wherein the second offset output gear (52) is freely rotatable about the second axis (B-B);
• wherein the first and second offset output gears (30,52) are rotatably adjustable about the first central output axis (A-A) and the second axis respectively, thereby to permit the second offset gear to be selectably co-axial with the first central output axis, or radially offset therefrom, and wherein the second offset output gear drives a final output shaft (50) of the drill/driver.
