having a main body, the main body having a first end portion, a second end portion and a third portion there between, wherein the first end portion and the second end portion extend radially outwards beyond the third portion; and an external sleeve is rotatably supported around the third portion by the first end portion and the second end portion. ## Claims ### Claim 1 A handle for a handheld appliance, the handle comprising: a main body comprising: a first end portion connectable to, or comprising, a power supply; a second end portion; and a third portion therebetween, wherein the first end portion and the second end portion extend radially outwards beyond the third portion; and an external sleeve configured to be gripped by a user to support the handle during use of the appliance, the external sleeve rotatably supported around the third portion by the first end portion and the second end portion. ### Claim 2 (depends on 1) The handle according to claim 1, wherein the sleeve is continuously rotatable with respect to the main body. ### Claim 3 (depends on 1) The handle according to claim 1, further comprising a power cable fixedly connected to the first end portion of the main body. ### Claim 4 (depends on 1) The handle according to claim 1, wherein the sleeve axially extends the length of the third portion of the main body such that a first edge of the sleeve abuts the first end portion of the main body and a second edge of the sleeve abuts the second end portion of the main body. ### Claim 5 (depends on 1) The handle according to claim 1, wherein an outer surface of the sleeve lies flush with at least an adjoining section of an outer surface of the first end portion of the main body. ### Claim 6 (depends on 1) The handle according to claim 1, wherein the third portion of the main body and the sleeve are substantially cylindrical. ### Claim 7 (depends on 1) The handle according to claim 1, wherein the handle is configured to receive a removable attachment. ### Claim 8 (depends on 7) The handle according to claim 7, wherein the sleeve comprises at least part of an attachment mechanism for attaching the removable attachment to the handle. ### Claim 9 (depends on 1) The handle according to claim 1, wherein the main body houses a fan unit and a heater. ### Claim 10 (depends on 9) The handle according to claim 9, wherein the first end portion of the main body further comprises at least one user operated button. ### Claim 11 (depends on 10) The handle according to claim 10, wherein the user operated button controls temperature settings or flow settings of the appliance. ### Claim 12 (depends on 9) The handle according to claim 9, wherein the second end portion of the main body comprises an air outlet of the handle. ### Claim 13 (depends on 1) The handle according to claim 1, further comprising a switch in the form of an at least partially annular collar, the collar surrounding the sleeve. ### Claim 14 (depends on 13) The handle according to claim 13, wherein the collar is configured to rotate with the sleeve around the main body and to slide axially with respect to both the sleeve and the main body. ### Claim 15 (depends on 14) The handle according to claim 14, further comprising at least one collar spacer attached to an inner surface of the collar, wherein the at least one collar spacer extends through a corresponding aperture of the sleeve and is axially retained between support rings, wherein the support rings extend circumferentially around the main body. ### Claim 16 (depends on 15) The handle according to claim 15, wherein the support rings are configured to slide axially with the collar. ### Claim 17 (depends on 16) The handle according to claim 16, wherein the support rings are coupled to an arm of an actuator such that axial movement of the collar actuates the actuator. ### Claim 18 (depends on 17) The handle according to claim 17, wherein the third portion of the main body is configured to inhibit circumferential rotation of one or both of the actuator arm and support rings. ### Claim 19 (depends on 16) The handle according to claim 16, wherein the third portion of the main body comprises a recess shaped to accommodate the actuator arm. ### Claim 20 (depends on 15) The handle according to claim 15, wherein the at least one collar spacer comprises a plurality of collar spacers circumferentially spaced around the inner surface of the collar. ### Claim 21 (depends on 15) The handle according to claim 15, wherein the at least one corresponding aperture in the sleeve is configured to abut sides of the at least one corresponding collar spacer in the circumferential direction and configured to allow axial movement of the at least one collar spacer within the sleeve. ### Claim 22 (depends on 14) The handle according to claim 14, wherein the collar has a plurality of axial positions. ### Claim 23 (depends on 22) The handle according to claim 22, wherein each axial position of the collar corresponds to a different operational state of the appliance. ### Claim 24 (depends on 22) The handle according to claim 22, wherein dimensions of the at least one corresponding aperture in the sleeve are such that the collar is axially moveable between the plurality of axial positions. ### Claim 25 (depends on 22) The handle according to claim 22, wherein the plurality of axial positions comprises three axial positions each corresponding to a respective different operational state, wherein the three different operational states are on with a heater engaged, off, and on with the heater disengaged. ### Claim 26 (depends on 1) The handle according to claim 1, wherein the appliance is a hair care appliance.
