A lancet-release mechanism is adapted to be incorporated into a lancing device. The lancing device is adapted to receive a lancet assembly therein. The lancing device is adapted to move the lancet assembly between a resting position, a cocking position, and a puncture position. The lancet-release mechanism comprises a lancet holder and a cantilever beam. The lancet holder forms a central aperture. The central aperture is adapted to receive the lancet assembly therein. The lancet holder further forms a plurality of protuberances thereon. The cantilever beam has a projection extending therefrom. The projection is adapted to engage the plurality of protuberances located on the lancet holder. The projection is adapted to separate the plurality of protuberances from each other so as to enlarge the central aperture.
