Abstract:
1. A combination tool and tool mounting device for temporarily and removably mounting the tool to a member, the combination comprising: said tool having a tool body having a tool axis and a tool off-set center of gravity off-set from said tool axis; said tool mounting device having a tool fastening element, said tool fastening element configured and arranged to removably secure said tool mounting device to the tool body; said tool mounting device including a member securing element having at least two opposable protrusions extending from said member securing element, said at least two opposable protrusions having opposable gripping surfaces, said opposable gripping surfaces being longitudinally and laterally spaced apart from one another, with a first of said gripping surfaces being displaced laterally on a first side of said tool axis of said tool and a second of said gripping surfaces being displaced laterally on a second side of said tool axis of said tool, and said off-set center-of-gravity of said tool is located on said second side of said axis of said tool; said tool mounting device further mounted on said tool at a location such that the off-set center of gravity of said tool lies outside a space between said opposable gripping surfaces and substantially within a plane of the space containing said opposable gripping surfaces; and said opposable gripping surfaces capable of engaging the member when the member is located between said opposable gripping surfaces and the tool rotates about the tool axis as a result of the off-set center of gravity of the tool, wherein rotation of said tool also rotates the tool mounting device and causes said first gripping surface and said second gripping surface to engage the member thereby temporarily and removably securing the tool to the member.
