Either of two quick fixes will solve that problem.
Remove the screw and gently pinch one thread with a pair of diagonal cutters, to distort the thread slightly. This will make it somewhat self locking when it's re threaded. If you've never done this before do only a little bit, and test until you find the amount that gives you a bit of resistance.
The other - safer - way is to remove the screw and paint it with rubber cement and let it dry. That'll give you a workable anti-vibration thread which you can adjust yet should stay put.
Either way, ad a stainless steel washer between the wingnut and outer cover. The cover works back and forth with lever movement, and a washer will reduce torque transfer to the wingnut.
