Pliers for applying ear tabs - has tab upper part piercing animal ear to enter tab lower part with automatic plier disengagement

摘要

The pliers comprise two jaws, spring loaded (14) into the open position. The upper jaw (15), holds a spindle (16), terminating in a spigot (17) locating inside the stem (3) on the tab upper part (2),. The lower jaw has a pivoting anvil (20), holding the lower part (7) of the tab, locating in a recess (9). The jaws are closed manually over the animal's ear and a pointed end (5) on the tab stem pierces the ear, passes through a hole (8) in the lower part and locks. When the pliers are released, an arm (19) between two stops (18) automatically disengages the locating spigot.
