ABSTRACT:
A tool for positioning a pair of objects with respect to each other is realized that comprises a toggle assembly attached to one end of a threaded shaft. The toggle assembly includes a pair of arm members pivotally attached about the shaft which are normally held in an open position wherein the arm members are jointed together end to end. A collapsing assembly is provided that is connected with the toggle assembly and disposed about the threaded shaft for causing the arm members to be collapsed about the threaded shaft, into a closed position. In this manner, the tool can be either inserted or removed from a hollow cylindrical object when the tool is closed into another hollow object. After insertion the first object is held securely to the second by allowing the toggle assembly to open prevention removal of the tool. Thereafter, the tool can be removed from both objects by collapsing the toggle assembly.
