How do I make it so shearing (custom shear item) a mob changes it's model and provides a custom drop

So basically there are two shear items. The Plucker, and just the regular shear. When the shear is used on the mob, entity changes model, loot table drop. When the plucker is used, entity changes to another model, drops a fruit (custom item, already in game) and remains available to be sheared which will cause it to go to the same model you would have if you normally sheared it.
