Patent ID: 7415768

Claim:
A shear system for an electric hair removing apparatus comprising at least one shearing unit having an outer cutter and an undercutter that are set in relative motion, at least one feeding device arranged to precede the shearing unit, the feeding device being configured to be set in motion relative to the outer cutter and to perform an oscillatory motion; and a drive mechanism configured to drive the relative motion of the outer cutter and the undercutter; wherein the amplitude of the oscillatory motion of the feeding device is smaller than the amplitude of the relative motion between the outer cutter and the undercutter, wherein the drive mechanism comprises a coupling mechanism that includes a driving lever and a transmission lever pivotally coupled to the driving lever, the driving lever being coupled to the undercutter and the transmission lever being suspended on the outer cutter, and wherein the drive mechanism further comprises a drive axle for the feeding device, secured to the transmission lever.
