How to stop tool animation when tool is unequipped?

I inserted local script in the tool and now it plays animation when I press "R", but it still plays animation after tool is unequipped, how to fix that? my current script:

local Player = game.Players.LocalPlayer
local Character = Player.Character or script.Parent
local Humanoid = Character.Humanoid
local UserInputService = game:GetService("UserInputService")

local AnimationID = 'rbxassetid://4868889544'

local key = 'R'
local debounce = true

UserInputService.InputBegan:Connect(function(Input, IsTyping)
    if  IsTyping then return end
    if Input.KeyCode == Enum.KeyCode[key] and debounce == true then
        debounce = false
        local Animation = Instance.new("Animation")
        Animation.AnimationId = AnimationID
        local LoadAnimation = Humanoid:LoadAnimation(Animation)
        LoadAnimation:play()
        wait(5)
        debounce = true

        end
    end)
