Abstract: A pneumatic stapler has a main body internally loaded with straight staple-forming wires and including a staple-driving and a wire-bending control chamber. A staple-driving element carrier is movably mounted in the staple-driving control chamber and divides the latter into a first and a second staple-driving gas flowing space. When the staple-driving element carrier moves in the second staple-driving gas flowing space to push one staple out of the main body into a workpiece, the initially isolated first staple-driving control chamber is now communicable with the wire-bending control chamber, allowing part of the gas supplied to the pneumatic stapler to flow into the wire-bending control chamber and move a wire-bending element mounted therein to bend one staple-forming wire into a staple. Therefore, the pneumatic stapler requires only one pressure source to complete both staple-driving and wire-bending operations and can have more staple-forming wires loaded therein to provide high convenience in use.

Abstract: A roll staple manufacturing process enabling production of a high yield of staples at an effectively reduced manufacturing cost including the steps of providing a wire strip consisting of multiple wires arranged side-by-side; holding the wire strip in place with a holding unit; cutting the wire strip with a staple forming module to provide multiple staple banks; using a push module to push the staple banks from the holding unit to a guide rail set; applying an adhesive element to the staple banks while the same are continuously moved forward by the guide rail set; using a counting element to count the wires of the staple banks passing therethrough, and cutting the staple banks with a cutting element when the number of the wires passed through the counting element reaches a preset value, so as to provide a staple strip; and winding the staple strip on a winding element to form a roll staple.

Abstract: A hand-operated coil stapler includes a main body having a linkage system provided therein; a staple driving mechanism assembled to a front end of the main body and including a complex staple driver; a pusher and magazine assembly connected to a bottom of the main body and including a push rod having a staple-pushing spring fitted therearound; and a coil staple unit formed of bar-shaped staples. When the main body is downward pushed, the linkage system brings the complex staple driver to bend and drive a first staple of the coil staple unit into a workpiece. Meanwhile, the complex staple driver comes into contact with the push rod and forces the latter backward to compress the staple-pushing spring. When the main body is released, the staple-pushing spring elastically moves the push rod forward, bringing a subsequent staple to a position below the complex staple driver for a next stapling operation.
