<p>An improved trigger mechanism particularly useful with a rotating frame animal trap, the present trigger mechanism comprises a rotary universal joint which allows angular displacement of the trigger mechanism about a frame of the trap on which said trigger mechanism is pivotally carried. Free ends of spaced prongs extending from the trigger mechanism toward the interior of the trap contact an animal entering the trap from any direction, sufficient force caused by such contact angularly displacing the trigger mechanism to spring the trap.</p> |
