How to make tool appear in different part of an animation?

I made an animation of equip, shoot, and unequip for a game, this is the script:

local tool = script.Parent
local handle = tool.Handle
local player = game.Players.LocalPlayer
local char = player.Character

script.Parent.Equipped:connect(function(eventMouse)
    eventMouse.Icon = "http://www.roblox.com/asset/?id=316279304"
    local animation = game.Players.LocalPlayer.Character.Humanoid:LoadAnimation(script.Parent.Equip)
    animation:Play()
end)

script.Parent.Activated:connect(function()
    local animation2 = player.Character.Humanoid:LoadAnimation(script.Parent.Start)
    animation2:Play()
    local mouse = player:GetMouse()
    local bulletClone = game.ReplicatedStorage.Bullet:Clone()
    bulletClone.Parent = game.Workspace
    bulletClone.Position = Vector3.new(mouse.Hit.Position)
end)

tool.Unequipped:connect(function()
    local anim = player.Character.Humanoid:LoadAnimation(script.Parent.Unequip)
    anim:Play()
end)

but the tool doesnt appear at the time of that animation, this is problem https://gyazo.com/d7eabff9d44357b5b42a25fbc7babe97 i want it to appear when u taken it out, same for unequip, tool disappears quickly than animation
