Pilot reported a nose wheel collapse and propeller strike during touch and go operations. The flight crew requested Airport Operations assistance and succeeded in moving the aircraft off of the runway for maintenance action.

Narrative

I was practicing touch and go landings at ZZZ. My first was uneventful and I made closed left traffic to Runway X while talking to the Tower. I was cleared for the option and came in for a normal landing. I did my normal GUMP check on final and all looked good. I touched down smoothly and continued down the runway; as I added throttle and raised the nose while still on the runway the nose wheel collapsed or retracted; the plane pitched forward with the prop striking the ground. It all happened in a nano second and I did not know what happened. My first thought was to close the throttle; pull the mixture off; turn off the master and the magnetos. I unbuckled and exited the airplane. Once outside I surveyed the damage and saw there was no fire or apparent fuel leaks. I reentered the airplane and turned off the gas and grabbed my hand held radio and notified the Tower of my situation. The fire trucks arrived. The firemen had an instrument that checked the heat signature of various parts of the airplane and they deemed it all normal with no fire. The Airport Operations Manager arrived and we discussed how to get the aircraft off the runway. He was able to contact someone at Company and after awhile we went over to their hangar and lead him out to assess the situation and figure out what equipment would be necessary to move the aircraft off the runway and to the hangar area. I don't know why the gear collapsed or retracted but we were able to extend it and safety wire it down so that it could be towed off the runway. My belief is there must have been some sort of mechanical failure.
