Powered fastener driver

A powered fastener driver includes a magazine containing fasteners therein, a drive blade movable in a reciprocating manner to discharge a fastener from the magazine for each drive cycle of the driveblade, a first trigger operable to initiate a drive cycle of the drive blade, and a second trigger movable between a first position, in which the first trigger is inhibited from moving to initiate thedrive cycle, and a second position, in which the first trigger is movable to initiate the drive cycle. 本发明提供了种动力紧固件驱动器，包括：弹匣，该弹匣中容纳有紧固件；驱动叶片，该驱动叶片能够以往复的方式移动，以在所述驱动叶片的每个驱动循环中从所述弹匣中释放紧固件；第触发器，该第触发器能够操作为启动所述驱动叶片的驱动循环；以及第二触发器，该第二触发器能够在第位置和第二位置之间移动，在所述第位置所述第触发器被阻止移动启动所述驱动循环，在所述第二位置所述第触发器能够移动启动所述驱动循环。
