FIG. 1 is a side view of a nail stapler equipped with a magazine according to the present invention.
Referring to FIGS. 1, a nail stapler 60 is equipped with a magazine according to the preferred embodiment of the present invention.
Referring to FIGS. 2 and 3, the magazine includes a first shell 10, a second shell 20, a plurality of positioning strips 30 and a pusher 40.
The first shell 10 includes a first end 11 and a second end 12. The first shell 10 further includes a first side 101, a second side 102, a lower edge 16 and an upper edge 17 that all extend between the first end 11 and the second end 12. The lower edge 16 is U-shaped when view in an end view. Thus, a groove 15 is defined in the lower edge 16 for receiving nails (not shown) that are generally formed together with one 22 another in a row. Each of the nails includes a head. A plurality of grooves 18 is defined in the first side 101 of the first shell 11. When the nails are received in the magazine, their heads are received in one of the grooves 18. An outlet element 13 is formed at the first end 11 of the first shell 10. The outlet element 13 defines a slot 132 through which the nails can be passed. The slot 132 includes a plurality of enlarged portions corresponding to the grooves 18. The outlet element 13 includes an outlet 131 through which the nails can be ejected so as to nail wood or the like. A connector 14 is secured to the second side 102 of the first shell 11 near the upper edge 17. The connector 14 defines a hole or recess 141. The first shell 11, the outlet element 13 and the connector 14 are conventional and will not be described in detail.
