I tried to get that shot for you with the tool removed but the door shut too fast me to time a shot. I will try again the next time I have the mill operating.

In the meantime.......
You can see the beginning of a cross bar behind the tooling which the two tensioned fingers pivot on. This cross bar has a protruding tab that mates up to the tooling slots when locked in place.

The two fingers appear straight but are inside circular at the back.
