The control rod 70 has two opposite ends protruding outwardly from the guiding channels 45 of the nail magazine 40. The control rod 70 is detachably locked in the positioning groove 451 of each of the guiding channels 45 of the nail magazine 40 to lock the push member 60 in the receiving space 41 of the nail magazine 40 temporarily. The push member 60 is a substantially rectangular block. The push member 60 is provided with a through hole 61 to allow passage of the control rod 70.

The nails 53 are serially connected with each other by a retaining module 50 which is slidable in the slideway 42 of the nail magazine 40. The retaining module 50 is pushed by the push member 60 to move toward the nail outlet 43 of the nail magazine 40. The retaining module 50 includes a plurality of limit rings 51 each surrounding a respective one of the nails 53 and a plurality of connecting pieces 52 detachably connected between the limit rings 51.

As shown in FIG. 3, the thrusting rod 30 is movable upward to detach from the nail guide slot 22 of the guide tube 20, so that the push member 60 is pushed by the elastic force of the elastic member 47 to push the nails 53 toward the nail outlet 43 of the nail magazine 40 and the nail guide slot 22 of the guide tube 20 so as to introduce the nails 53 through the nail outlet 43 of the nail magazine 40 and the nail guide slot 22 of the guide tube 20 into the bore 21 of the guide tube 20. At this time, only a single one of the nails 53 is allowed to enter the bore 21 of the guide tube 20.

As shown in FIG. 4, when the striking head 31 of the thrusting rod 30 is hit by a hammer, the thrusting rod 30 is movable downward to break and separate the respective limit ring 51 and the respective connecting piece 52 of the retaining module 50 from one of the nails 53 and to move one of the nails 53 downward so that one of the nails 53 is ejected outwardly from the bore 21 of the guide tube 20 and is forced into an object “A”, such as a wooden board.

As shown in FIG. 5, when the striking head 31 of the thrusting rod 30 is hit successively, one of the nails 53 is forced into the object “A” completely, and the respective limit ring 51 and the respective connecting piece 52 of the retaining module 50 are injected outwardly from the openings 15 of the handle 10 and the breaches 25 of the guide tube 20.

In such a manner, the above-mentioned procedures as shown in FIGS. 3-5 are repeated successively. Thus, the push member 60 is pushed by the elastic member 47 to push the nails 53 into the bore 21 of the guide tube 20 successively, and the nails 53 are ejected outwardly from the bore 21 of the guide tube 20 successively, so that the nail pusher can push and eject the nails 53 successively.

As shown in FIG. 6, the striking head 31 of the thrusting rod 30 has a circular shape and is hit by a hammer.

As shown in FIG. 7, the striking head 31a of the thrusting rod 30a has an elongate shape and is hit by the user's palm.

Accordingly, the push member 60 is pushed by the elastic member 47 to introduce each of the nails 53 into the bore 21 of the guide tube 20 successively, and the nails 53 are ejected outwardly from the bore 21 of the guide tube 20 successively, so that the nail pusher can push and eject the nails 53 successively. In addition, the push member 60 is pushed by the elastic member 47 to introduce each of the nails 53 into the bore 21 of the guide tube 20 successively, so that the nails 53 are fed into the bore 21 of the guide tube 20 automatically, thereby facilitating the user feeding the nails 53.
