▎ 摘　　要

NOVELTY - The device has a screw rod whose outer surface is provided with a screw thread. An inner surface of a fixing opening is provided with a screw thread and engaged with the screw thread of the screw rod. A rubber sleeve is made of soft natural rubber material. An inner surface diameter of the rubber sleeve is equal to an outer surface diameter of a clamping rod. An upper end surface of a plate portion is connected with a surface of a supporting plate (2). A rotating disc drives the screw rod to rotate. USE - Graphene-based heating device used in house. ADVANTAGE - The roller facilitates the movement of the heating device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the graphene-based heating device. Air outlet (1) Supporting plate (2) Case (3) Bottom plate (4) Splicing frame (5)
