There is provided a spacing assembly (200) comprising a support body (210) and a moveable body (212) received in a guide track of the support body (210). The first guide track allows movement of the moveable body (212) in a spacing direction (203) but restricts the moveable body (212) in a lateral direction (205) perpendicular to the spacing direction (203). An adjuster (222) comprises first and second spiral channels (702, 704), which are arranged about a common point (706) on a surface of the adjuster (222) and engage a first lug (440) of the support body (210) and a second lug (442) of the moveable body (212), respectively, such that the adjuster (222) is rotatable about the common point (706). Rotation of the adjuster (222) drives the moveable body (212), under the lateral restriction of the first guide track (202), to move relative to the support body (210) in the spacing direction (203).

The present disclosure relates to an adjustment drive (50) for an adjustable spacing comb (26) for a hair cutting appliance (10) and to a hair cutting appliance (10) that is fitted with an adjustable spacing comb (26). The present disclosure further relates to a method for operating an adjustable spacing comb (26) for a hair cutting appliance (10). The adjustment drive (50) comprises an actuator (52) for actuating a movable comb portion (40) of the adjustable spacing comb (26) with respect to a blade set (16) of the hair cutting appliance (10), a manually operable rotation element (64), particularly a manually rotatable rotation element (64) and an encoder (70) particularly a rotary encoder (70), that is configured to detect rotary movement of the rotation element (64) and to output a respective user input signal, wherein the actuator (52) is operated on the basis of the user input signal.

The present disclosure relates to an adjustment drive (58) for an adjustable spacing comb (26) for a hair cutting appliance (10) and to a hair cutting appliance (10) that is fitted with an adjustable spacing comb (26). The adjustment drive (58) comprises an actuator (60) that is configured for actuating a movable comb portion (40) of the adjustable spacing comb (26) with respect to a blade set (16) of the hair cutting appliance (10), a drivetrain (62) for coupling the actuator (60) and the movable comb portion (40), wherein the drivetrain (62) comprises a reduction gear unit (66), and a location detection unit (80) comprising a rotary encoder (84), wherein the rotary encoder (84) is coupled to an output shaft (68) of the reduction gear unit (66).

A method for assembling a hair cutting appliance is presented. A body is provided with a power switch connected to a power source. A drive system within the body is in selective electrical communication with the power source. A cutting unit is electrically connected to the drive system. An optical sensor is mounted to the body to sense a pre-defined skin-hair edge. A control circuit within the body is electrically connected to the optical sensor. A switching element is electrically connected with the control unit. The switching element is switchable by the control circuit between a conducting state and a non-conducting state. The switching element is switched to the non-conducting state when a sensed condition of the optical sensor exceeds a first pre-programed threshold. The first pre-programmed threshold is stored in the control circuit. A method is provided for assembling a power transform module used with a hair cutting appliance.
