Instrument / Applicator / Laser Diagram

We think this depicts some from of instrument, applicator or transfer mechanism with an expanding output or projectile some kind. Could this even be a diagram for a laser pistol? Interestingly these 3 dots ascending in size either indicates flow and direction or laser and light as it has appeared in other Agrograms notably the laser light sail diagram. More investigation will be required to define the meaning or purpose behind this most curious Agrogram.
