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 nailing unit includes a nail box, a nail magazine, a nail pushing block, a tail buckle switch, a nail limiting block fit together with a nail guiding plate through slits is provided. The nail magazine includes a heat-treated guide rail assembly mounted with a nail splitting plate at the end near the nail guiding plate. The nail pushing block connected to a spring is formed with three nail pushing feet adapted to a first, second, and third gaps. The nail guiding plate includes two connecting wings and forms a low-lying guide plate therebetween. Each angle between the guide plate and each connecting wing is respectively fixedly provided with a positioning step along the longitudinal direction.

In one aspect, a conveyor belt fastener is provided having a rigid body made from a strip of cold-rolled or cold-drawn material such as steel. The body has an upper plate portion, a lower plate portion, and loop portions connecting the upper and lower plate portions. The upper and lower plate portions each have a variable cross-sectional thickness laterally thereacross including raised walls projecting outwardly and ribs projecting inwardly. The fastener has at least one attachment member, such as a staple, for connecting the plate portions to a conveyor belt end and the raised walls protect the staple once driven into the conveyor belt end.

The hammer tacker includes a shell, a handle, and a striking mechanism. The shell is made of a mixture of fiberglass and nylon by injection molding. The shell encloses a receiving room and has a bottom opening extending along the longitudinal direction of the shell and communicating with the receiving room. The handle is disposed on the rear end of the shell. The striking mechanism is made of metal and includes a magazine and a striker. The magazine is received in the receiving room. An end of the magazine is pivotally connected to the rear end of the shell, and the other end tends to move outward due to an elastic element. At end of the striker is disposed on the inner wall of the shell. When the magazine is hit upward, the striker strikes the nails out.

A handle lock for a handle-operated tool, wherein the handle lock includes a stowed position and a deployed position. When biased into the stowed position, the handle lock is integrated and blended to a body of the tool. The deployed handle lock is stable upon forcible motion of the closed handle, the lock preferably requiring a secondary action to release the handle and stow the lock. Optionally, the handle lock can be stowed by forcibly pressing the handle toward the open or closed position. A spring bias holds the lock in the stowed position.

A track release system for a fastening tool such as a staple gun that may be exposed and operated substantially from under the tool. A track pull and selectively linked operative features are preferably fitted near a rear of a track. A user normally turns the tool upside down to access the track pull features for reloading fasteners. The track pull and associated elements are not exposed on a side of the tool body but rather on the rear and bottom. While the track release structure is below the track, the enabling structure remains vertically compact whereby the size of the tool need not be extended downward to accommodate the operative elements.
