The base link also has a distal portion pivotally coupled to a proximal portion of the thumb link. The thumb link has a distal portion pivotally coupled to at least one thumb of a plurality of thumbs. The plurality of thumbs are coupled together and pivotally coupled to the bracket. The bracket includes a first lock hole for locking the assembly in a stored position. At least one of the proximal portion of the thumb link, the distal portion of the base link or one of the thumbs include a second lock hole that is in axial alignment with the first lock hole when the assembly is in the stored position. The assembly also includes a removable pin that is received in the first and second lock holes for locking the assembly in the stored position.
