Claim 5:
6. A clinch block configured to be disposed on a distal end of a clinch arm, the clinch arm is pivotally connected at a proximal end to a pneumatic stapling tool, wherein a forward direction is defined extending away from the proximal end and towards the distal end, and wherein a rearward direction is defined extending away from the distal end and towards the proximal end, wherein the pneumatic stapling tool is configured to dispense staples each staple comprising a crown and a pair of staple legs, wherein the crown is disposed in a crown direction, wherein the clinch block comprises:
a U-shaped curved profile configured to bend the staple legs in a direction perpendicular to the crown direction, wherein the direction perpendicular to the crown is one of the forward direction and the rearward direction;
wherein the clinch block comprises a bottom portion, a forward curved portion and a rearward curved portion of the U-shaped curved profile, wherein the forward curved portion extends in the forward direction away from the bottom portion, and wherein the rearward curved portion extends in the rearward direction away from the bottom portion; and
wherein the U-shaped curved profile is configured to bend each pair of staple legs following one of the forward curved portion in the forward direction and the rearward curved portion in the rearward direction;
wherein an entire width, in a width direction perpendicular to the forward direction or the rearward direction, of the clinch block comprises a U-shaped cross section, and the U-shaped curved profile comprises a pair of parallel staple leg tracks,
wherein a thickness of the clinch block, in a thickness direction, increases from the bottom portion to the forward curved portion along the forward direction and increases from the bottom portion to the rearward curved portion along the rearward direction, wherein the thickness direction is perpendicular to the width direction and the forward direction or the rearward direction;
wherein the pair of staple leg tracks comprise a pair of parallel grooves formed in a surface of the U-shaped curved profile.
