摘要： A hair cutting appliance comprises an external cutting member and an internal cutting member arranged rotatable to the external cutting member for cutting hair. The internal cutting member is driven via a first coupling element by a drive spindle (24) rotatable about an axis of rotation (35) and having a first spindle part (26) arranged to be driven by a drive, and a second spindle part (30) arranged to be coupled to the internal cutting member, the first and second spindle parts (26, 30) being displaceable relative to each other in an axial direction parallel to the axis of rotation (35); wherein the second spindle part (30) comprises a second coupling element (34) which is coupled to the first coupling element for transmitting, during operation, a driving torque about the axis of rotation (35) from the drive spindle (24, 24a) to the internal cutting member; wherein one of the first and second spindle parts (26, 30) comprises an abutment element (36) and the other of the first and second spindle parts (26, 30) comprises an abutment surface (38) arranged to cooperate with the abutment element (36) for transmitting, during operation, the driving torque from the first spindle part (26) to the second spindle part (30); wherein the abutment surface (38) is arranged at an angle α relative to a tangential direction relative to the axis of rotation (35), wherein 0˚

摘要： The invention relates to a hair-cutting unit for a shaving device. The hair- cutting unit comprises a hair-cutting element and a telescopic drive-shaft mechanism (3). The drive-shaft mechanism comprises a first shaft-segment (21), which is in telescopic engagement with a co-rotating second shaft-segment (22), which is in telescopic engagement with a co-rotating third shaft-segment (23). A spring mechanism (5) presses the first 5 telescopic shaft-segment and the third telescopic shaft-segment away from one another. In an embodiment, the first and second telescopic shaft-segments (21, 22) are in mutual tiltable engagement and/or the second and third telescopic shaft-segments (22, 23) are in mutual tiltable engagement. The invention provides improved skin-contour-following capacity of a shaving device, while at the same time the required installation space for the drive-shaft 10 mechanism remains restricted.
