Reassembled Clutch, retaining washer, and flexor head piece

Here I have removed all necessary parts from the cavity and reassembled them as they should be to show their relationships to each other. The clutch is inside the white donut piece on the right, and prevents the legs from rotating freely forward and backwards. This is attached to the flexor or head piece on the left, which gets attached to the leg "bones". This allows the legs to be spread apart wider or narrower.
