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()

            wait(1)
            canattack.Value = false
        end
    end
end)
