Would you happen to know the size of the spline? If it's 11/32", I recommend our 39-205 folding crank handle. This may work for you.
Though I wonder exactly how they're falling off. Tell me, when the handle falls off, does it bring the corkscrew-shaped bore out with it? If so, then the problem is not with the handle, but the operator itself. That bore is not meant to come out and it means your gears are stripped. The only way to fix it is to replace the operator itself. |

I'm referring to the hole in the handle. See the image below of the 39-205 to see its spline.
