EXTENSION DEVICE FOR POWER SCREWDRIVER

摘要

A device is provided for increasing the distance between the power head and bit of a power screwdriver, particularly one intended for driving drywall screws. The device includes a polygonal drive rod which replaces the original drive rod in the tool's clutch mechanism, a cylindrical sleeve which is press fit over the new drive rod and receives the original drive rod at the other end thereof, and a cylindrical adaptor which receives the sleeve internally and connects the clutch mechanism to the depth gauge of the tool, the bit still projecting from the depth gauge. Any number of the extension sets can be interconnected together to increase the extension length as desired. With the extension in use drywall screws can be driven in areas previously not accessible due to interference with the power head, and the operator can drive screws in ceilings while standing on the floor rather than on scaffolding.
