▎ 摘　　要

NOVELTY - A stable graphene heating film comprises film body, where the top of the film body is fixedly connected with a heating sheet, and one side of the heating sheet is provided with a bump that is fixed and connected with film body. The top of bump is lapped with a power supply connecting wire (4). One side of bump far away from heating sheet is provided with the mounting seat clamps film body. The bottom of mounting seat is provided a pressing block. The side of film body on one side is provided an adjusting groove (16), the inner width of adjusting groove gradually decreases from left to right. The inner wall of adjusting groove is connected with symmetrically distributed connecting block, between two sets of connecting blocks (19) fixedly connecting with telescopic rod (17). An upper part of movable block (30) is fixedly connected with rod, and limiting groove (41) connected with straight slot, where limiting groove and straight slot are matched with inserting rod (28). USE - Stable graphene heating film. Uses include but are not limited to material learning, micro-nano processing, energy, biomedicine and drug delivery. ADVANTAGE - The guide rod is located in the U-shaped limiting frame, namely fixing the whole, convenient for adjusting the exposed length of the power supply line, avoiding the multiple pulling caused by the power line and the heating sheet of the contact, and avoiding the danger. The power supply connecting line enters the adjusting groove part is hung on the two groups of hook, at this time, the sliding sleeve can be through the vertical rod, the fixing block moves the movable block, so that the distance between the two group of hooks is adjusted, so as to adjust the part of the connecting wire extending out of the heating sheets, reducing the part length of heating film exposed outside the power lines when using, avoiding power line exposed outside of power supply lines is pulled off caused by tension. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing an enlarged structure of a stable graphene heating film.
