Abstract:
1. A wrenching tool extension for attaching to a wrenching handle, said wrenching tool extension comprising: a shaft having a drive end adapted for attachment to a wrenching handle and a head receiving end defining an axial bore and further adapted to receive interchangeable socket heads; a magnetic arm including a rod and a magnet affixed to one end of said rod, said magnetic arm axially received in said axial bore and oriented such that said magnet is positioned at said head receiving end of said shaft, said magnetic arm being axially translatable in said bore, said magnet being axially translatable relative to said shaft between a retracted position in which said magnet bears against said shaft head receiving end, and extended positions in which the magnet is adjustably extended away from said shaft head receiving end; a side adjustment feature positioned on an external intermediate surface of said shaft and mechanically interfaced with said magnetic arm to axially translate said magnetic arm with respect to said shaft; wherein said head receiving end comprises a retention ball extending radially from a surface of said head receiving end, and said rod defines a notch therein, said notch selectively positionable to be in registration with said retention ball; wherein said notch in registration with said retention ball provides a socket releasing configuration, and further wherein said notch in other than registration with said retention ball provides a socket locking configuration; and wherein said notch is in registration with said retention ball when said magnet is arranged in said retracted position relative to said shaft, and said notch is in other than registration with said retention ball when said magnet is arranged in any of said extended positions in which the magnet is adjustably extended away from said shaft head receiving end.
