摘要： A shaver head (12) for an electric shaver (10) has at least two hair-cutting units (13), each comprising an external cutting member and an internal cutting member which is rotatable relative to the external cutting member, and each supported by a supporting portion (26). The supporting portion is linearly movable under the bias of a spring member (30) relative to a base portion (20) of the shaver head between a first, retracted, position and a second, extended, position. The shaver head has a locking mechanism (30, 32) for selectively locking the supporting portion in a locked position relative to the base portion. This allows a user to select different shaving modes.
