Claim:
A spring actuated stapling device, comprising: a body; a track along a bottom of the body to guide staples toward a front of the stapling device; a handle pivotably attached to the body wherein the handle includes an initial rest position where the handle is pivoted to a farthest position away from the body, and a pre-release position where the handle is pivoted toward the body; a striker movable vertically within the body between an initial rest position above the track and a lower-most position in front of the track; a power spring disposed within the body linked to the striker, wherein the power spring includes a relaxed free state, a pre-stressed rest state, and an energized deflected state, the power spring being deflected and energized as the handle moves from the farthest position to the pre-release position; a cage at least partially confining the power spring to normally retain the power spring in the pre-stressed state, wherein at least the power spring and cage form a spring/cage subassembly, the spring/cage subassembly being separately movable from the body and from the handle; and the spring/cage subassembly having an upper position wherein the power spring is in the pre-stressed rest state, and a lower position wherein the power spring is in the pre-stressed rest state.
