These are the external components of a spinning fishing reel.

• The reel handle is moved in a rotating movement by a person's hand
• The bail and line roller rotate about the the line spool and prevent the line from coming off of the line spool
• The bail can be flipped open which allows the line to come off of the line spool
• The line spool moves up and down while the bail and line roller rotate about it

Here's a video of a demonstration of the fishing reel I took apart prior to destruction:
