The drive mechanism may include a gear, an eccentric element coupled to the gear and a motor mechanism configured to drive the gear. The drive mechanism may also include a substantially elongated drive link having a proximal end and a distal end, the proximal end coupled to the gear via the eccentric element, and a spring coupled to, and configured to being driven by, the distal end of the drive link. The spring being configured to directly drive the pivot shaft in a reciprocal fashion. A swing drive assembly including a blade and pivot shaft is also described.
