NOVELTY - The utility model claims a graphene preparation reaction box body, comprising a reaction box device and a hanging mechanism; two sides of the upper end of the reaction box device is provided with a hanging mechanism; the graphene growth substrate is placed on the upper end of the supporting plate; the fixing mechanism installed on the side surface of the limiting strip is inserted into the inner cavity of the mounting groove; the inner cavity side wall of the limiting rod is provided with a ball; the ball and the arc slide rail are in rolling connection, so that the limiting rod contacts the inclined limiting block; the limiting rod is retracted to push the movable block to move; the limiting rod passes through the limiting block, the limiting rod and the movable block are pushed to rebound, so as to form a self-locking; convenient and fast to limit the limiting strip to the supporting plate; when the supporting plate is pushed into the inner cavity of the supporting groove, the two ends of the supporting plate are provided with arc groove; the groove is clamped with the arc convex block; the supporting plate can be fixed and clamped after pushing into the cavity of the supporting groove; The invention effectively prevents the loss caused by the sliding and falling of the supporting plate.
