ABSTRACT:
A hand-held staple gun comprises a housing, a driver, a spring means, a handle, and a safe actuation mechanism. The safe actuation mechanism includes a swing means, a link, and an actuation control rod. The swing means is pivotally secured to the housing and the link is pivotally connected with the swing means. When the staple gun is not in use, the link cannot engage the driver even if the handle is pressed down, and when the staple gun is in use, the actuation control rod is pressed upward into the housing, so that the actuation control rod pushes the swing means, making the link engage the driver and therefore possible to drive staples out of the staple gun when pressing down of the handle.
