Abstract
A tilt anvil assembly is disclosed which includes a center rod, a head assembly, and a torsion spring configured to pivot the head assembly relative to the center rod. The head assembly has a locking collar defining a locked position preventing pivotal movement of the head assembly, and an unlocked position allowing pivotal movement of the head assembly. The torsion spring selectively engages the locking collar to maintain the locking collar at either the locked or unlocked position.
