151


is slidable within the slide rail


132


. The revolving cylinder


14


is connected with the nail-pushing plate


15


by a flexible steel cord


16


. A conduit


17


is disposed between the revolving cylinder


14


and the frame body


13


for the steel cord


16


to pass therethrough. Via the steel cord


16


, the revolving cylinder


14


can drive the nail-pushing plate


15


to reciprocally move along the slide slot


131


of the frame body


13


. The head section


12


has a bottom face


121


formed with an inlet


122


.




The nail magazine


2


is formed with multiple longitudinally extending nail channels


21


which are parallel to each other and have different patterns. One end of each nail channel


21


extends out of the nail magazine


2


to form an opening


211


. Through the opening


211


, different types and lengths of rows of nails


3


can be loaded into the nail channels


21


. One side of the nail magazine


2


near the frame body


13


is provided with two dovetail tenons


22


. The frame body


13


is formed with two transversely extending dovetail mortises


133


corresponding to the dovetail tenons


22


. By means of transversely inserting the dovetail tenons


22


into the dovetail mortises


133


, the nail magazine


2


can be connected with the frame body


13


and transversely moved within the dovetail mortises


133


. The end of each nail channel


21


opposite to the opening


211


is formed with a passage


212


through which the nail-pushing plate


15


can be upward pushed into the nail channel


21


for pushing the row of nails


3


. The nail-pushing plate


15


can respectively push the rows of nails


3


in the nail channels


21


into the head section


12


of the gun body


1


. The cross-section of the passage


212


is smaller than that of the nail channel


21


, so that the rows of nails


3


are received in the nail channels


21


without dropping out from the passage


212


.




Two sides of the inlet


122


of the head section


12


are respectively formed with two holes


123


. A locating steel ball


124


and a spring


125


are embedded in each hole


123


. The spring


125


serves to push the steel ball


124


to protrude from the bottom face


121


of the head section


12


. The distance between the inlet


122


and the two locating steel balls


124


is equal to the distance between two adjacent nail channels


21


. Accordingly, when any of the nail channels


21


is aimed at the inlet


122


of the head section


12


, at least one of the two locating steel balls


124


is inlaid and retained in the nail channel


21


adjacent to the nail channel


21


aimed at the inlet


122


so as to locate the nail magazine


2


.




The nail-pushing plate


15


is driven by the revolving cylinder


14


via the steel cord


16


to move on the frame body


13


. Prior to installation of the nail magazine


2


, the revolving cylinder


14


is switched to drive the nail-pushing plate


15


to a lowest position of the slide slot


131


. At this time, the nail magazine


2


can be loaded into the frame body


13


from one side thereof. The dovetail tenons


22


of the nail magazine


2


are inserted into the dovetail mortises


133


, whereby the nail magazine


2


can be transversely moved within the dovetail mortises


133


. The nail magazine


2


has multiple nail channels


21


in which multiple rows of different nails


3


are loaded. Accordingly, as necessary, a user can transversely move the nail magazine


2


to aim the nail channel


21


in which the nails


3


are loaded at the inlet


122


of the head section


12


. At this time, the locating steel ball


124


of the head section


12


is retained in the opening


211


of the adjacent nail channel


21


to locate the nail magazine


2


. Then, the user can switch the revolving cylinder


14


to drive the nail-pushing plate


15


to move upward along the slide slot


131


. At this time, the nail-pushing plate


15


can move from the passage


212


into the nail channel


21


to push the nails


3


from the inlet


122


into the head section


12


for nailing operation. When using different nails


3


, the user can first switch the revolving cylinder


14


to drive the nail-pushing plate


15


to move to the lowest position of the slide slot


131


. At this time, the nail magazine


2


can be transversely moved to select the necessary nails


3


. Thereafter, the revolving cylinder


14


is switched to drive the nail-pushing plate


15


to push the nails


3


into the head section


12


for nailing operation. Accordingly, it is unnecessary to detach the nail magazine and take out the row of nails for replacement.




In conclusion, the nail magazine


2


of the present invention has multiple parallel nail channels


21


in which multiple rows of different nails


3


are received. The dovetail tenons


22


of the nail magazine


2


can be transversely moved within the dovetail mortises


133


of the frame body


13


, whereby any of the nail channels


21


can be aimed at the inlet


122


of drive head section


12


of the gun body


1


. The revolving cylinder


14


can drive the nail-pushing plate


15


to reciprocally move along the slide slot


131


of the frame body


13


. Each nail channel


21


is formed with a passage
