ABSTRACT:
A tool for releasably gripping a rod comprising: a structure supporting a rod clamping assembly which is movable relative to the structure; a release to cooperate with the clamping assembly to release a said rod gripped by the clamping assembly; and means for producing the relative movement wherein the means for producing the relative movement includes a motion converter to convert rotary motion of a first member into linear motion on a second member and vice versa; a clutch connected to transmit rotary motion to the first member; means for selectively engaging and disengaging the clutch; and a spring connected to bias the second member in opposition to the linear motion produced by the rotary motion; the second member being connected to transmit the linear motion to the clamping assembly when said clutch is engaged; the clutch disengaging means disengaging the clutch when the relative motion has produced a predetermined travel of the clamping assembly and the spring being connected to return the second member and the clamping assembly to its original position upon disengagement of the clutch.
