ABSTRACT:
A holding apparatus includes a first clamp and a second clamp. Each clamp having a handle, and a coupler for coupling the handles of the clamps together. The coupler includes a first rod and a second rod, with each rod having a right angled leg, the legs being shorter than the rod, and the ends of each rod being threaded. A coupling engaging the threads on one end of each of the rods to adjustably join the rods together and wing nut engages one thread in interfering engagement. Connecting elements connect the legs to a respective clamp handle. Each connecting element includes a ring rotatably surrounding the second leg and having an integral stem projecting radically from the ring. The stem projects through a clamp handle to permit pivotal movement of the clamp handle around the stem, thereby providing five axes of movement between the two clamps. Each connecting element has a nut threadedly engaging the leg for movement into interfering engagement with the ring to prevent rotational movement around the leg and a nut threadedly engaging the stem for movement into interfering engagement with the clamp handle to prevent movement of the clamp handle about the stem.
