DETAILED DESCRIPTION
Referring to FIG. 2 and FIG. 3, a magazine 5 has a nail gate 4 and a nail groove 50, which cooperate with each other to prevent the different length nails from being erroneously mounted into the nail groove 50. The nail gate 4 can be inserted into the nail groove 50 or be disposed at one end of the nail groove 50. The nail gate 4 has an elastic piece (not labeled), a stopping plate 41 extending from an upper end of the elastic piece, in a direction of perpendicular to the elastic piece, and a tongue 42 perpendicularly extending from an intermediate portion of the elastic piece, parallel to the stopping plate 41. The stopping plate 41 has a stopper 411 in V-shaped groove. The tongue 42 has a tilted cutout 421.
The nail groove 50 has an upper nail head rail 50a, a lower nail head rail 50b and a nail shaft passage 50c, connecting with each other. The upper and lower nail head rails 50a, 50b guide two nail heads 2a, 3a of a longer and a short nails 2, 3, respectively. The nail shaft passage 50c supports the longer and short nails 2, 3 so that two nail shafts 2b, 3b are aligned in a shaft direction.
As shown in FIG. 4, the magazine 5 further has a rear base 6, which has a nail groove 60 similar to and connecting with the nail groove 50. The nail gate 4 can be inserted into the nail groove 60 or be disposed at one end of the nail groove 60. In addition, the nail groove 60 has an entrance 61 at one end connecting with the outside, by which the longer and short nails 2, 3 are entered.
In assembly, the nail gate 4 is disposed on one end of the nail groove 50 (60) by a pivot 44 drilling through an ear hole 42 of the nail gate 4 and one locating hole (not labeled) on the nail groove 50 (60). The pivot 44 fixes the nail gate 4 thereon by cooperating with a fixing ring 45. In addition, the elastic piece of the nail gate 4 is inserted into an embedded groove 55 (65) of the nail groove 50 (60), which the embedded groove 55 (65) is formed at one end of the nail groove 50 (60). Moreover, the stopping plate 41 and the tongue 42 of the nail gate 4 are respectively inserted into the nail shaft passages 50c (60c) of the nail groove 50 (60). In an alternative modification, the stopping plate 41 of the nail gate 4 is inserted into the upper nail head rail 50a (60a) of the nail groove 50 (60), and the tongue 42 of the nail gate 4 is inserted into the nail shaft passage 50c (60c) of the nail groove 50 (60).
In assembly, assuming the nail gate 4 is disposed in the nail groove 60 of the rear base 6, the following specification will describe the different states of assembling two different length nails 2, 3 in different position. Firstly, when an operator assembles longer nails 2 (as shown in FIG. 7) into the nail groove 60 maintaining a tilted angle between the longer nails 2 and the nail groove 60, the beginning longer nail 2 firstly touches and pushes the titled portion 421 of the tongue 42 of the nail gate 4 (as shown in FIG. 8). That is the thrust of beginning longer nail 2 makes the elastic piece of the nail gate 4 to produce an elastic deformation or swing, and be out of the nail groove 60 (as shown in FIG. 9). Thus, the nail groove 60 is opened and allows the nail head 2a and the nail shaft 2b respectively to enter into the upper nail head rail 60a and the nail shaft passage 60c. Secondly, when an operator assembles short nails 3 (as shown in FIG. 10) into the nail groove 60, corresponding to the lower nail head rail 60b, the titled beginning short nail 3 firstly touches and pushes the titled portion 421 of the tongue 42 of the nail gate 4 (as shown in FIG. 11). That is the thrust of beginning short nail 3 makes the elastic piece of the nail gate 4 to produce an elastic deformation or swing, and be out of the nail groove 60 (as shown in FIG. 12). Thus, the nail groove 60 is opened and allows the nail head 3a and the nail shaft 3b respectively to enter into the lower nail head rail 60b and the nail shaft passage 60c. Thirdly, when an operator assembles short nails 3 (as shown in FIG. 13) into the nail groove 60, corresponding to the upper nail head rail 60a, the titled beginning short nail 3 firstly touches and pushes the stopper 411 of the stopping plate 41 of the nail gate 4 (as shown in FIG. 14). The stopper 411 stops the beginning short nail 3 in its V-shaped groove. Thus, the nail gate 4 can not produce an elastic deformation and prevents the nail head 3a and the nail shaft 3b of the short nail 3 into the corresponding upper nail head rail 60a and the nail shaft passage 60c. Therefore, the nail gate 4 avoids the short nail 3 being erroneously mounted into the nail groove 60.
In another alternative modification, the stopping plate 41 of the nail gate 4 is inserted into the upper nail head rail 50a (60a) of the nail groove 50 (60), and the tongue 42 of the nail gate 4 is inserted into the nail shaft passage 50c (60c) of the nail groove 50 (60) (as shown in FIG. 6). The tongue 42 can still open the nail groove 50 (60) by a thrust of the beginning longer or short nail 2, 3 and allows the nails 2, 3 to be assembled into the nail groove 50 (60). The stopping plate 41 still can stop the short nail 3 erroneously mounted into the nail groove 50 (60).
