The two locking pawl portions are connected to the release lever portion through the connecting arms. The release lever portion has a base and arms. The arms serve as an axis around which the release lever portion can pivot. Each locking pawl portion is mounted on a post on the lower wall of the base adjacent a respective reel, and each locking pawl portion is biased by the connecting arms to engage its respective reel lower flange teeth to lock the reel.
