Patent attributes
A multiple flex-shaft adapter coupled to an electric drill has a housing assembly attaching to the drill at one end and to a plurality of flex-shafts at an opposite end. The flex-shafts have specialized drill bits attached thereto for performing different nail operations. A gear assembly is located in the housing assembly for transferring power from the drill to the plurality of flex-shafts. Preferably, an operator selects a switching member corresponding to a desired one of the plurality of flex-shafts and pushes the member horizontally into the housing. After entering the housing assembly, the switching member rises up towards the gear assembly. Subsequently, the operator inserts the desired one of the plurality of flex-shafts into the housing assembly through a receiver to engage the gear assembly. In turn, power is transferred from the drill through the gear assembly to the desired one.
