NOVELTY - The utility model claims a graphene heating film welding fixing mechanism, comprising a fixing bracket, an electric control box set on the upper part of the fixing bracket, a hydraulic cylinder electrically connected with the output end of the electric control box, a driving shaft connected with the telescopic rod of the hydraulic cylinder, a pressing block connected with the driving shaft; a supporting seat coaxially set with the pressing block; a mounting frame set on the outer circumference of the supporting seat; a connecting column set between the mounting frame and the supporting seat; a vacuum pump connected with the supporting seat and a vent hole uniformly set on the supporting seat; the utility model claims a graphene heating film welding fixing mechanism electric control box controls the hydraulic cylinder to do telescopic movement, so that the telescopic rod of the hydraulic cylinder drives the driving shaft to perform protection movement; so as to make the pressing block move to the direction relative to the supporting seat; in addition, it is convenient for the air hole on the supporting seat to absorb the graphene heating film due to the action of the vacuum pump.
