Abstract
A drive assembly is provided. The drive assembly includes a gear housing comprising a support surface for a hand of a user, a gear drive mechanism disposed within the gear housing, and a handle member disposed on the gear housing proximate to the support surface. The gear drive mechanism includes a first drive gear rotatable about a first axis of rotation and engaged to the handle member, a second drive gear rotatable about a second axis of rotation, and a driven member engaged to the implement and driven by the second drive gear about a third axis of rotation that extends through the support surface. The driven member is disposed at least partially outside of the gear housing and is driven only when the handle member is moved from an unfired position to a fired position. The handle member does not cross the third axis of rotation during such movement.
