The invention deals with the field of screwing heads for small trigger-type pumps or triggers and namely for applying, on vessels, triggers equipped with a threaded securing ring nut (). This screwing head () is rotated around a vertical axis through a permanent magnet-type clutch and comprises four rollers () which tighten the toothed ring nut () when screwing it; said rollers () are supported by vertical arms () whose axes are arranged at 90° one from the other on a circumference with its center on the rotation axis of the screwing head. The vertical arms () and the four rollers () are simultaneously carried along a radial direction towards said ring nut through an oscillating movement.
