This technology has been implemented in Geneva for decades.

Referring to the first figure, the conventional Geneva wheel mechanism is mainly composed of a combination of a driving wheel set and a passive wheel set. The driving wheel set includes a driving shaft 11, a crankshaft 12 and a sector disk 13; the passive wheel group includes a passive shaft 21, a radiation groove 22, a concave arc 23 and a turntable 24.
