Abstract
The improved trigger structure for nailing guns includes a substantially C-shaped pin having a longer arm and a shorter arm; a trigger having two upright side plates each of which has a first lug with a pivot hole at a top end thereof for pivotally connecting the trigger to a gun body and a second lug with a pivot hole at a bottom end thereof for receiving the longer arm of the pin, and a trigger element having an upright plate body with two opposite lugs. Each side plate has a first curved indentation at a suitable position between the first lug and the second lug for mounting the shorter arm of the pin. A second curved indentation is provided at a bottom edge of each of said side plates for receiving and hence positioning the shorter arm of the pin. The shorter arm of the pin may be mounted on the first curved indentation to restrict displacement of the trigger element to put the nailing gun in a single strike mode or it may be mounted on the second curved indentation to allow free displacement of the trigger element to put the nailing gun in a continuous strike mode.
