My on and off/ volume button on my ford zx2 radio came off and now the shaft justs goes in when I try to fix it. I was told it can't be fixed and I would have to get a whole new radio. If I can pull it out and fix it somehow let me know.

There is no method of repair for you to fix this easily -- even the dealership doesn't open radios for internal repairs. There are some repair facilities that do - do a web search and you will find some.
Just buy a new Face plate or dash. The whole thing will come off. The faceplate is around 50 buck or less it include a Square radio hole and new knobs for the AC/Heater and Hazard switch. it is new face and the radio is square so you can install aftermarket radio Amazon has it and this web site http://www.crutchfield.com/p_120995720/Ford-Mercury-Factory-Integration-Adapter.html?tp=3486
