How do I add a cooldown my punching tool?

How would I add a cooldown to one of these scripts? I need it t where the player cannot spam left click and punch. The animations don't finish if they spam it

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local tool = script.Parent
local swingsound = tool:WaitForChild("Swing")
local canattack = tool:WaitForChild("CanAttack")


tool.Activated:connect(function()
	local choose = math.random(1,4)
	canattack.Value = true
	if choose == 1 then
		local swing1animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch1)
		swingsound:Play()
		swing1animation:Play()
	elseif choose == 2 then
		local swing2animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch2)
		swingsound:Play()
		swing2animation:Play()
	elseif choose == 3 then
		local swing3animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch3)
		swingsound:Play()
		swing3animation:Play()
	elseif choose == 4 then
		local swing4animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch4)
		swingsound:Play()
		swing4animation:Play()
	end
end)

tool.Deactivated:connect(function()
	canattack.Value = true
end)

tool.Unequipped:connect(function()
	local hum = char:WaitForChild("Humanoid")
	for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
 		anim:Stop()
	end
end)

local tool = script.Parent
local hitsound = tool:WaitForChild("Hit")
local canattack = tool:WaitForChild("CanAttack")
local plr = tool.Parent.Parent
local char = plr.Character or plr.CharacterAdded:wait()
local larm = char:WaitForChild("Left Arm") -- this can be changed im only using this for the R6 body type
local rarm = char:WaitForChild("Right Arm")
local rleg = char:WaitForChild("Right Leg")
local lleg = char:WaitForChild("Left Leg")
local dmg = 5*10-- this can be changed im only using this for the R6 body type

larm.Touched:connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if canattack.Value == false then
		if hum then
			canattack.Value = true
			hitsound:Play()
			hum:TakeDamage(dmg) -- u can change this value
			wait(1)
			canattack.Value = false
		end
	end
end)

rarm.Touched:connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if canattack.Value == false then
		if hum then
			canattack.Value = true
			hitsound:Play()
			hum:TakeDamage(dmg) -- u can change this value
			wait(1)
			canattack.Value = false
		end
	end
end)

lleg.Touched:connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if canattack.Value == false then
		if hum then
			canattack.Value = true
			hitsound:Play()
			hum:TakeDamage(dmg) -- u can change this value
			wait(1)
			canattack.Value = false
		end
	end
end)

rleg.Touched:connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if canattack.Value == false then
		if hum then
			canattack.Value = true
			hitsound:Play()
			hum:TakeDamage(dmg) -- u can change this value
			wait(1)
			canattack.Value = false
		end
	end
