Mine has a lock nut on the threaded rod portion, and if I neglect to check it once in awhile, it will loosen up, and the rod will slowly back out of the tube it's threaded in - and stick out the side farther as a result. I keep forgetting to lock-tite the nut. Anyways, if yours has the nut, you can thread the handle back into the tube then lock the nut.
