The tool looks like it punches a rod or insert out of or into position. The bottom part of the tool slides over a rod or bolt and then the handle is moved to push a short pin ether out of position or into position. My guess is the tool is used to disassemble/assemble some kind of linkage having a rocker cam arm of some sort. This is a scientific wild assed guess (SWAG), of course.
