A high-speed gunpowder actuated nail with a toothed tube includes: a nail member including an outer threaded portion; a tubular member including an inner threaded portion screwed to the outer threaded portion; an actuating portion mounted to the tubular member; and a percussion cap mounted to an end of the tubular member remote from the nail member. As such, it can be applied for effective screw connection of a threaded rod of small size, and the threaded rod and the nail member are arranged to be perpendicular to each other so that it has high structural strength, which improves the assembly strength to solve the difficulty and high cost of processing the inner thread of the tubular portion of the conventional one-piece high-speed nail, and solve the problem of insufficient screw connection strength due to the insufficient teeth of the conventional hanger.

A high-speed nail combined with an inner-toothed tube having an expandable padding includes: a main body including a tubular member and an expandable flange, the tubular member including a first space and a threaded portion, the expandable flange integrally projecting form the tubular member and expending in a nailing direction to define a second space, the second space being in communication with the first space; a drive pin connected to the tubular member by insertion in the nailing direction, including a nail head and a nail body connected to each other, the nail head being located in the first space, the nail body extending from the first space to the second space; and a gunpowder actuating unit received in the first space.
