摘要： A hand tool system having a longitudinally extendable operating component and a longitudinally extendable support component for reaching a remote and/or confined location. The operating component includes a worm drive having a proximal end for attachment to a rotational drive device such as a drill motor, and a distal end for attachment to a rotational driver having a first end which can accept a connector engagement device such as a screwdriver head or other type bit and a second end from which extends a pivotable arm. The support component has a pivotable distal end with a securement member releasably securable to a structure, a hand engageable proximal end, and an exterior surface slidingly engageable with the pivotal arm extending from the driver. In use, an operator manipulates the support component with one hand while powering the drill motor with the other hand such that the support component engages the pivotable arm of the driver to thereby leverage and stabilize the driver during rotational movement of the screwdriver or other bit head and consequent placement of a screw member.
