How would stop this tool from working after I unequip it?

This tool launches a fire ball from your hand. Mr problem is that it keeps working even after I unequip it. How do I fix it?

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local Debounce = true
local UIS = game:GetService("UserInputService")


script.Parent.Equipped:Connect(function()
	
UIS.InputBegan:connect(function(Key, GPE)
	if Key.KeyCode == Enum.KeyCode.Q and not GPE then
		if Debounce == true then
			Debounce = false
			local Animation = Player.Character.Humanoid:LoadAnimation(script.Animation)
		Animation:Play()
		local Part = Instance.new("Part", game.Workspace)
		Part.CFrame = Player.Character["Right Arm"].CFrame * CFrame.new(0, 0, -2) 
		Part.Anchored = true
		Part.Transparency = 1
		Part.CanCollide = false
		Part.Size = Vector3.new(0.8, 0.8, 0.2)
		
		Player.Character.Humanoid.WalkSpeed = 0
		
		local Decal = Instance.new("Decal", Part)
		Decal.Texture = "rbxassetid://301362847"
		local Decal2 = Instance.new("Decal", Part)
		Decal2.Texture = "rbxassetid://301362847"
		Decal2.Face = "Back"
		
		
		
		for i = 1, 11 do
			Part.Size = Part.Size + Vector3.new(0.5,0.5,0)
			wait()
		end
		
		local FireBall = Instance.new("Part", game.Workspace)
		FireBall.CFrame = Part.CFrame * CFrame.new(0,0,-3)
		FireBall.Transparency = 1
		FireBall.Size = Vector3.new(1.2, 2.4, 0.8)
		
		local Sound = Instance.new("Sound", FireBall)
		Sound.SoundId = "rbxassetid://182382770"
		Sound:Play()
		
		local Fire = script.ParticleEmitter:Clone()
		Fire.Parent = FireBall
		
		local BodyVelocity = Instance.new("BodyVelocity")
		BodyVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
		BodyVelocity.Velocity = Mouse.Hit.lookVector * 80
		BodyVelocity.Parent = FireBall
		
		FireBall.Touched:Connect(function(hit)
			local Humanoid = hit.Parent:FindFirstChild("Humanoid")
			if Humanoid then
				Humanoid:TakeDamage(40)
				FireBall:Destroy()
			elseif
				hit.CanCollide == true then
				local Explosion = Instance.new("Explosion", game.Workspace)
				Explosion.Position = hit.Position
				
				
				
				
				local Sound3 = Instance.new("Sound", hit)
				Sound3.SoundId = "rbxassetid://304529688"
				Sound3:Play()
				
				for i, v in pairs(hit.Parent:GetChildren()) do
					print(v)
					local FindFire = v:FindFirstChild("Fire")
					if not FindFire then
						local GiveFire = Instance.new("Fire", v)
						GiveFire.Name = "GiveFire"
					end
				end
				
				
				FireBall:Destroy()
				
				
				
				
				wait(2)
				for x, y in pairs(hit.Parent:GetChildren()) do
					local DeleteFire = y:FindFirstChild("GiveFire")
					if DeleteFire then
						DeleteFire:Destroy()
					end
				end
				
				
			end
			
		end)
		
		
		wait(0.70)
		
		for x = 1, 15 do
			Part.Size = Part.Size - Vector3.new(0.5,0.5,0.5)
			wait()
			
		end
		Part:Destroy()
		Player.Character.Humanoid.WalkSpeed = 16


		wait(3)
		Debounce = true
		end
		
	end
	
	


	
end)
end)



--??
	script.Parent.Unequipped:Connect(function()
	UIS.InputBegan:connect(function(Key, GPE)
		if Key.KeyCode == Enum.KeyCode.Q and not GPE then
			Debounce = false
		end
	end)
end)

So try adding a variable called anything

local Equiped = false

and when you equip the tool just set it to True, and then do a if statement to check if its Equipped

script.Parent.Equipped:Connect(function()
Equiped = true
UIS.InputBegan:connect(function(Key, GPE)
if Equiped == true then
--code here

and then when the player unequips it just make Equiped equal false

script.Parent.Unequipped:Connect(function()
Equiped = false
    UIS.InputBegan:connect(function(Key, GPE)
        if Key.KeyCode == Enum.KeyCode.Q and not GPE then
            Debounce = false
        end
    end)
end)
