FIELD: electronic devices. ^ SUBSTANCE: one of shaft extensions has flange mounting on its end at least two stops for axial displacement which are sequentially engageable with spring-loaded axially movable pusher mounted within case, its central conical part being engageable with rod; locking mechanism is installed on one of case butt-ends. In addition, locking mechanism can be made in the form of flexible rod for engaging at least two slots on side surface of flange. Pusher geometry axis can be tilted through angle affording perpendicular position of tilted pusher surface relative to axis of engageable rod; butt-end on stops or on pusher is flat and perpendicular to input shaft axis. ^ EFFECT: simplified design, enhanced reproducibility of frequency fixation. ^ 3 cl, 3 dwg |
