Claims
- 1. A tool for handling workpieces of generally circular cross-section, comprising a first jaw and a second jaw each having a base provided with workpiece-gripping projections, and operating means including a pair of pivotally interconnected shanks enabling relative swinging of said jaws in a plane transverse to the pivotal axis between a withdrawn position allowing insertion of a workpiece between said jaws and a working position in which the projections of said jaws are mutually interleaved, said jaws being swingably mounted on said shanks with swing axes parallel to said pivotal axis for facilitating the interleaving of their projections upon approaching said working position; said shanks being provided with respective backing surfaces disposed between said swing axes and said jaws for engaging the bases thereof at least in said working position.
- 2. A tool as defined in claim 1 wherein said backing surfaces are curved about said swing axes.
- 3. A tool as defined in claim 1 wherein said backing surfaces are gabled and form sections adjoining one another at an obtuse angle.
