The trigger lever (2) is tilted about an axis formed by a spindle (3) across the top and is moved backwards against the rod (4) extending rearwards, connected to it by a hinged joint. Between a pressure element (21) parallel to the trigger lever and tilting about a second axis (22) below the first axis, is a leaf spring (26) which is stronger than the first spring. The spindle forming the second axis is close to the first spindle and parallel to it. The pressure element is U-shaped in cross section and its sides (23) enclose the trigger lever. The leaf spring is bent into a V shape, being also retained between the sides of the U section. The bottom of the pressure element terminates in a nose (25) which fits into a recess (24) across the bottom of the trigger lever, the width of the recess determining the amount of movement of the pressure element towards it.
