Safety trigger for nailer

Abstract

The present invention relates to a safety trigger for a nailer, which is used to eject nails into a work object through a muzzle, with a gliding bar being pushed upward, when the muzzle is set on the work object, allowing an ejection switch to be operated, the safety trigger comprising: a trigger body, hingedly mounted on the nailer and operating the ejection switch when pulled up; a blocking part, rotatably mounted on a transverse shaft through the trigger body, either pointing towards a peripheral surface around the ejection switch or pointing aside, thus blocking or allowing the operation of the ejection switch by the trigger body; and a spring around the shaft, leaning against the gliding bar and against the blocking part; wherein, when the muzzle of the nailer is set on the work object and the gliding bar is consequently pushed upwards, the blocking part is turned aside, allowing the trigger body to be pulled upwards and operate the ejection switch, and when the muzzle is taken away from the work object, the trigger body and the blocking part return to an original position, with the blocking plates preventing the trigger body from touching the ejection switch.
