A magazine assembly and a stapler including the same are provided. The magazine assembly includes a base and a rail assembly. The base has a first end portion and a second end portion. A direction from the second end portion toward the first end portion is defined as a first direction. The rail assembly is disposed on the base and adapted for a staple unit to movably abut thereagainst along the first direction. The rail assembly includes a first rail and a second rail which are separate. A first side wall of the first rail has at least one guiding portion extending in the first direction. Each guiding portion is adapted for a head of a T-shaped staple to slidably engage therewith along the first direction. The second rail is adapted for a U-shaped staple to abut thereagainst.

The present invention provides an irrigation staple insertion device and method for setting staples to secure flexible tubing to the ground. The device offers significant advancements toward the prevention of deformation of the tubing from driving the staples too far into the ground, and alleviates the need for an installer to bend down to install each staple. The staple insertion device may include a piston nested within an outer chamber, where the outer chamber includes a slot for holding an irrigation staple to be inserted into the ground over an irrigation tube. The piston may be structured and nested in the outer chamber such that it can only travel a pre-determined distance through the chamber that is equal to the length of the staple less the thickness of the irrigation tube.

A stapler for a fence post incorporates a tubular sleeve configured to hold a single staple, in a first sleeve end and a bolt configured to be inserted into a second sleeve end and to moveably rest within the interior space of the sleeve. When inserted into the sleeve, a first end of the bolt is in contact with the staple head positioned within the first sleeve end. An impact surface is secured to a second bolt end and remains outside of the sleeve. A wingnut is secured through an aperture within the sleeve adjacent the second sleeve end. The distal end of the wingnut selectively engages a notch cut into the surface of the bolt adjacent the impact surface and having a length which generally corresponds to that of a staple. The device is configured to transfer a force from the impact surface to the staple head thereby driving the staple into a surface such as that of a fence post.

A spring energized fastening tool with compact, rigid, low friction working elements is disclosed. A torsion power spring includes forward extending arms with the arms pressing each other proximate a front distal end of the spring. A cantilevered lever links to a handle and engages the spring adjacent to the striker. A bottom loading staple track unlatches and opens through a simple pulling-out action. Structures are provided to enable fitment with a formed sheet metal handle and housing. The fastening tool is particularly simple to assemble, powerful, and of low operating effort.
