NOVELTY - The utility model claims a graphene sensor technology field, specifically a flexible graphene sensor, comprising a protective box, a graphene sensor, a screw rod and a limiting device, the protective box is provided with storage cavity, the left upper corner of the protective box is provided with a first screw hole; the graphene sensor storage in the inner cavity of the storage the utility model, when the graphene sensor is not used, the rotating rod drives the screw to rotate so as to drive the strip frame, the graphene sensor and the sealing plate rotate, rotating to the protective box of the storage, through the protection box to protect; the limiting device can further limit the transverse rod, before the transverse rod rotates, pulling the vertical stretching spring through the pull ring, driving the limiting block to move, and then rotating the transverse rod, the transverse rod enters the guide groove, loosening the pull ring, the spring reverse pushing limiting block, one end of the transverse rod is inserted into the limiting groove, under the action of the spring, further limiting the transverse rod.
