1. A nail-driving gun trigger assembly comprising:
a gun housing including a hand-grip that defines an inner space and a window opening which is in spatial communication with said inner space; a trigger mechanism including a trigger piece, a safety latch, and a release button, said trigger piece extending through said window opening into said inner space and being movable relative to said hand-grip between a non-actuating position and an actuating position, said safety latch being mounted movably on said trigger piece and being movable relative to said trigger piece between locked and unlocked positions, said release button being mounted movably on said trigger piece and being movable relative to said trigger piece between first and second positions, said release button and said safety latch being co-movable with said trigger piece relative to said hand-grip when said trigger piece is moved between said non-actuating and actuating positions; and an urging unit for restoring said trigger piece to said non-actuating position, said safety latch to said locked position, and said release button to said first position; wherein said trigger piece is stopped from moving from said non-actuating position to said actuating position by engagement between said safety latch and said hand-grip when said safety latch is disposed at said locked position; and wherein said release button is in sliding contact with said safety latch so as to push said safety latch to move from said locked position to said unlocked position when said release button is pushed to move from said first position to said second position, thereby disengaging said safety latch from said hand-grip and permitting movement of said trigger piece together with said safety latch and said release button from said non-actuating position to said actuating position. |
