Hand tool for plugging conduit

摘要: A conduit-plugging hand tool comprises a conduit-insertable shaft assembly and toggle-lockable pincer assembly. The coaxial inner outer shafts, bulb member. member is spatially situated intermediate the distal ends of shafts such that when are coaxially displaced relative to one another, may be axially compressed radially expanded for selectively blocking conduit. first second jaws, toggle-locking mechanism. jaw coupled proximal end, end. toggle-mechanism operates displace along axis jaw. members thereby displaceable another longitudinally compressing effecting radial expansion.
