Tool's parts are not staying with the handle?

script:

game.Players.PlayerAdded:Connect(function(plr)
    if plr:IsInGroup(2818059) then
        wait(0.5)
        local clone = game.ServerStorage["Separatist ID"]:Clone()
        clone.Parent = plr.Backpack
    end
end)

the tool goes to my backpack, but when I equip it only the handle appears in my hand, the tool parts (which are children to the Handle) appear where I edited them in workspace
