The invention relates to a single-firing trigger mechanism for a nailing machine with a receptacle for receiving a swiveling element pivotably on a second positioning shaft. The other end of the swiveling element with a torsion spring is pivotally connected to a contact element on a third positioning shaft and, in addition, the top end of the contact element is disposed at a height to be in contact with a safety lever. The safety lever should be extended into the inside of the trigger and pressed against the contact element so as to be shifted in the direction of the firing pin. Thereafter, the user can press down the trigger again, thereby causing the contact element to be in contact of the firing pin for the next single-firing operation.
