Abstract

The ratchet mechanism has a ratchet cam (18) attached to the push-button slider (12) cooperating with the bent guidance end of a wire hoop (24), which is moved along the cam surface upon operation of the push-button slider, for sidewards and subsequent location in a ratchet notch for holding the push-button slider in a defined position. The push-button slider has a shaped spring element for biasing the wire hoop on a direction transverse to the push-button axis.
