How to have scripts only run in a specific model?

If i use this script it works fine for 1 "tree" but if i want to copy and paste the tree multiple times on the map it does not work anymore. The script is placed inside the tree, how do i get it so the script only works within that model?

local click = script.Parent:WaitForChild("ClickDetector")

click.MouseClick:Connect (function(player)
    for _,v in pairs (game.Workspace.SmallTree1.Leaves:GetChildren()) do
    if v:IsA("Part") then--Checks if the Child that is inside the Model is ClassName Part.
    v.Anchored = false
    end
end
    for _,v in pairs (game.Workspace.SmallTree1.Logs:GetChildren()) do
    if v:IsA("Part") then--Checks if the Child that is inside the Model is ClassName Part.
    v.Anchored = false
    end
end
end)
