Powered nail-driving tool with an angle-adjustable nail magazine

A powered nail-driving tool suitable for driving a leading nail from a selected one of two different ranks of juxtaposed nails, the two different ranks being oriented along first and second lines of inclination, respectively, said powered nail-driving tool comprising:

• a body including a barrel and a shell opposite to each other along an impacting line, said barrel defining a nail-discharging passage which extends along the impacting line, and which has feeding and guiding regions proximate to and distal from said shell, respectively, said barrel having an access opening which is communicated with said feeding region in a radial direction relative to the impacting line, and which is adapted to admit entry of the leading nail into said feeding region;
• a striking rod which is disposed in said shell, and which is thrust into said feeding region along the impact line in response to a manual operation to thereby force the leading nail through said guiding region and out of said barrel for nailing;
• a handle which extends radially from said shell, and which includes proximate and distal segments relative to said shell;
• a nail magazine including:
• a leading edge wall which extends in a longitudinal direction, and which has proximate and distal edge ends opposite to each other in the longitudinal direction,
• a nail-feeding channel which is elongated in a transverse direction relative to the longitudinal direction, which has a proximate storing zone adjacent to said leading edge wall and a distal storing zone opposite to said proximate storing zone in the transverse direction, and which is adapted to accommodate the selected one of two different ranks of nails oriented along a corresponding one of the first and second inclination lines in such a manner that a head and a pointed end of the leading nail are respectively adjacent to said proximate and distal edge ends, and
• a torque-adjustable biasing member adapted to urge against a trailing nail of the selected one of the two different ranks of nails oriented along a corresponding one of the first and second inclination lines such that the leading nail of the selected rank is sequentially lifted outwardly of said leading edge wall while being oriented in the corresponding one of the first and second inclination lines;
• a linking arm including a connected end secured to said leading edge wall, and an anchoring end pivotally mounted on said barrel about a pivot axis such that the leading nail of the selected rank is lifted into said feeding region through said access opening, and such that said nail magazine is turnable about the pivot axis between a first angular position, where the first inclination line of the leading nail of the selected rank is aligned with the impacting line, and a second angular position, where the second inclination line of the leading nail of the selected rank is aligned with the impacting line;
• and
• an adjustably retaining member disposed to releasably arrest movement of said nail magazine relative to said distal segment in either one of the first and second angular positions.
