The invention relates to a drive system for a hand-held device for locally piercing human or animal skin, having a drive means which is arranged to provide a rotary drive movement； and a conversion mechanism (4b) which couples to the drive means for tapping the rotary drive movement and is arranged to provide a linear forward and backward movement starting from the rotary drive movement, the conversion mechanism (4b) having: a wobble plate arrangement arranged on a bearing means and coupling via a rotary joint to a distal joint component which is accommodated by the bearing means； a wobble plate formed on the wobble plate arrangement which, in operation, performs a wobbling motion due to the rotary driving motion； a tap, which is coupled to the wobble plate and is adjusted to provide the forward and backward linear movement for tapping by cooperation with the wobble plate； and an adjustment component, which is coupled to the wobble plate arrangement and is displaceably arranged such that for adjusting a stroke of the forward and backward linear movement provided at the tap, a tilt of the wobble plate with respect to the longitudinal direction can be changed by displacing the adjustment component. Furthermore, a drive module and a hand-held device are provided.
