Abstract
A single-and-continual shot changeover device for a nailing gun includes a trigger shaft positioned in an interior of a trigger body, a trigger inner member pivotally connected with an intermediate fitting stage of the trigger shaft, which also has two slide shaft stages at two sides of the fitting stage for two springs and two press buttons to fitting around respectively. The two press buttons are elastically pushed to shift outward to engage one of two—an upper and a lower—grooves of the two sidewalls of the trigger body. When the two press buttons are pressed inward, the trigger inner member can be shifted up and down to let the press buttons secured at either of the two limit grooves by means of the trigger shaft. Then the trigger inner member is controlled to separate or not from the safety connect rod for changing firing a single shot or continual shot.
