ABSTRACT:
A safety trigger mechanism for a stapler includes a trigger member for pivotally coupling to the stapler at a pivot shaft and having an opening. A frame has a middle portion pivotally coupled to the trigger member at a pivot axle and having one end aligned with the opening of the trigger member for allowing the frame to be actuated by a slide of the stapler. A block is secured on the frame and has a recess for receiving a switch button of the stapler and for preventing the switch button from being actuated by the frame when the frame is not actuated, such that the staples may be prevented from being shot inadvertently.
