Okay, I'll try to understand your question and I am showing a couple of images to try to explain my answer. The "firing pin" is held back by a part called the extractor/sear. When you pull back the cocking piece the extractor/sear moves up into a mating recess at the bottom of the bolt and holds the "firing pin" back until released by pulling the trigger. The model 67 does not cock on opening or closing the bolt, it has to be done by pulling the cocking piece back. The silver wing in front of the cocking piece is the saftey, it is engaged by moving to a vertical position and disengaged by moving it right to a horizontal position.
I hope this is what you are looking for.
