Rotary hand tool with a crank arm incorporated into its handle

A hand tool comprising:

• a means for rotating a tool shank about its longitudinal axis in a uninterrupted continuous manner, a means for controllably coupling said hand tool to a threaded fastener, whereby said hand tool can be efficiently coupled and rotated to drive a rotary fastener, wherein said coupling means is a force produced by an operator urging a gripable secondary handle with a inner bearing surface coaxial with said axis, an end bearing surface on at least one end, having said handle contained within the tool;
• so that said force is transmitted towards the fastener through the tool shank to the fastener, wherein said rotating means is a pivotably mounted crank arm connected to said shank, producing a torque about the tool axis when rotated by an operator, wherein said handle includes a storage cavity positioned along its longitudinal axis, having adequate dimensions to store a portion of said operating crank, said mounting located so the crank can be rotated from a detented working position to a non-working position within said cavity, preventing any coaxial rotation of handle with respect to the shank, allowing the tool to be operated in either a conventional or continuous fashion when driving a fastener.
