Automatic trigger in the threading, essentially characterized in that when a gear is cut, the threading drive of the machine tools engages a rack, extending on a rod to the outside of the carriage, so that when this control is operated the rack is moved, at the same time that the thread advance begins; to delimit this advance it is provided with an adjustable stop, with which the zipper trips and as a result it makes the screw back to its original position; to accelerate the retraction of said control, they carry, practiced, the rod of the rack and the control shaft, ramp-shaped recesses, through which some pins act through their corresponding springs; the drive shaft has another slot where a ball is housed, to keep it positioned during the operation.
