NOVELTY - The utility model claims a fixing device for sticking graphene paper film on back of floor, comprising a bottom frame, an adjusting frame, a first air pressure rod, a rotating rod, a connecting arm, a clamping seat, a limiting plate and a rotating seat; the top part of the bottom frame is provided with an adjusting frame; two ends of the top part of the adjusting frame are slidingly provided with a clamping seat; the centre of the top part of the adjusting frame is rotatably mounted with the centre of the rotating rod; The utility model drives one end holder to slide through the first air pressure rod expansion end the bottom frame; at this time, the connecting arm on one end holder drives the rotating rod to rotate, so as to drive the other end holder to slide through the other connecting arm; adjusting the distance between the two clamping seats; it is convenient for fixing the floor with different sizes, and the two clamping seats move inwards or outwards synchronously; it is convenient to limit the fixed floor position; it is convenient for reducing the loss of the graphene paper film when the subsequent film.
