Abstract: A fastener device includes a fastener member having a planar element and having a cutting member for engaging into a board, and one or more teeth formed on the planar element, one or more reinforcing ribs extended from the planar element for reinforcing the planar element, and a head formed on top of the planar element for being engaged with driving tools and for limiting the engagement of the fastener member into the board. The planar element may include two panels foldable relative to an intermediate board for forming the head and for forming a two-layer structure for the head, and may include one or two longitudinal members extended from the panels.

Abstract: A nail manufacturing machine includes two cutting tools movable to cut a wire into a nail blank, a sorting member having a channel for receiving the nail blank, an indexing wheel disposed below the sorting member and having a number of nail blank holding grooves formed in the outer peripheral portion for stably and horizontally supporting the nail blank without complicated nail blank holders and retaining members and for allowing the nail blank to be effectively hammered or machined by a nail machining tool, and a driving device includes a spindle for moving the tool member to machine the nail blank, and for moving the cutting tools to cut the wire into the nail blank.

Abstract: A fastener device includes a fastener member having a planar element and having a cutting member for engaging into a plasterboard, and one or more teeth formed on the planar element, one or more reinforcing ribs extended from the planar element for reinforcing the planar element, and a head formed on top of the planar element for being engaged with driving tools and for limiting the engagement of the fastener member into the plasterboard. The planar element may include two longitudinal members secured together and having an identical shape. The head may include a board and two panels secured to the board for forming a two-layer structure.

Abstract: A fastener device includes a fastener member having a planar element and having a tip for engaging into a plasterboard, and one or more teeth formed on the planar element for engaging with the plasterboard, a cutting member disposed between the planar element and the tip, one or more reinforcing ribs extended from the planar element for reinforcing the planar element, and a head secured on top of the planar element for being engaged with driving tools and for limiting the engagement of the fastener member into the plasterboard. The fastener member may include one or more ratchet projections extended from the planar element.

Abstract: A fastener device includes a fastener member having a planar element and having a tip for engaging into a plasterboard, and an anchoring device having one or more teeth formed on the planar element for engaging with the plasterboard and for preventing the fastener member from being disengaged from the plasterboard. A cutting member is disposed between the planar element and the tip for facilitating an engagement of the fastener member into the plasterboard. The planar element may include one or more reinforcing ribs for reinforcing the fastener member, and an enlarged head for limiting an engagement of the fastener member into the plasterboard.

Abstract: A mechanism for binding nails includes a cutter for cutting a rubber tube into rubber bands. A sleeve has a number of blades coupled to one end. A hook is disposed below the cutter for hooking the rubber band and for moving the rubber band to the blades. A rod is slidably engaged in the sleeve for expanding the blades and the rubber band. The rod includes a magnetic device for attracting nails. A ring is disposed beside the blades and moved relative to the blades for moving the rubber band away from the blades so as to bind the nails automatically.
