<p>The arrangement has a blind track (22) whose one edge is attached to a shaft. A holder has a slot with a closed end and an open end, where slot width matches with the thickness of a pivot. The holder sets up a stopper for the pivot/pin, when the blind track is removed against the effect of a clockwork motor, such that the pivot is held abutting against the stoppers through the bias of the motor in the slot.</p> |
