Claim:
A hair clipper having a moving lower blade comprising: an eccentric cam, which is connected to a rotary shaft of a motor installed in a main body and an eccentric shaft formed on the eccentric cam, which is inserted into a fixing groove formed in an upper blade fixing plate, the eccentric cam driving the fixing plate to vibrate horizontally, wherein the lower blade is mounted on a blade support, such that the lower blade can move horizontally, and is connected to one end of a link, the central portion of which is connected to the blade support, and the other end of which is connected to the lower surface of an upper blade fixing plate, an upper blade being fixed to the lower surface of the upper blade fixing plate, and thus, when the upper blade fixing plate vibrates horizontally by the rotation of the motor, the lower blade vibrates on the blade support in the direction opposite to the vibration of the upper blade by way of the link.
