UNIT_INVENTORY_CHANGED, but use arg1 to filter out 'player' so it doesnt update too much.

UNIT_INVENTORY_CHANGED is fired when any piece in the PaperDollFrame is changed. And even more, actually.

You can check if your weapon has changed by setting a variable to the name of the weapon, and compare it. If it not the same then your weapon has changed, obviously:

local lastweapon, compareweapon
function addon:UNIT_INVENTORY_CHANGED(unit)
    if unit ~= 'player' then return end
    compareweapon = GetInventoryItemLink("unit", 16)
    if lastweapon ~= compareweapon then
        //do stuff
    end
    lastweapon = compareweapon
end

This is drycoded however, it has not been tested ingame.

You also want to react to this on a timer - say, after 0.25 seconds. Otherwise, you may react to multiple occurrences of the event as it can happen in rapid succession.

Yes, you need to throttle it down, 0.25 is simply too low, try something along the lines of 1-2 seconds. UNIT_INVENTORY_CHANGED is a horrible event, only seconded to BAG_UPDATE and the event that warns for durability updates (its name escapes me atm). It will fire when something new is added (or destroyed) in any of your bags, either via looting, splitting a stack etc (with the exception of moving items in your bank), in addition to an item being equipped or unequipped. Unfortunately, it is the only event that Blizzard has provided us, in order to reliably check for equipped item changes, in 4 years

well anything like sleep in lua ??

i found nothing using google, curious

thank you again

Unfortunately, no. You will have to use an OnUpdate() - to the effect of:

do
	local last_update = 0
	local updater = CreateFrame("Frame", nil, UIParent)

	updater:Hide()
	updater:SetScript("OnUpdate",
			  function(self, elapsed)
				  last_update = last_update + elapsed
				  if last_update >= 0.25 then
					  DoStuffHere
					  self:Hide()
				  end
			  end)

	function YourAddOn:UNIT_INVENTORY_CHANGED(event, unit)
		if unit ~= "player" then return end
		if not updater:IsVisible() then
			last_update = 0
			updater:Show()
		end
	end
end	-- do

Obviously you'll need to modify it slightly to suit your needs.
