▎ 摘　　要

NOVELTY - Reaction device comprises a device body (1) and a fixing frame (3) that is welded to both sides of the device body, where a reaction plate (2) is fixed at top of a temperature conducting plate. The both sides of the reaction plate are provided with mounting side plate. The mounting side plate is provided with a mounting rod. The mounting rod is mounted on the fixing frame. A mounting groove is arranged in the inner cavity of the mounting rod. A spring is fixedly connected to the bottom of the mounting groove. One end of the mounting rod is connected with a telescopic rod. The telescopic rod is slidably connected with the inner wall of the mounting rod. The mounting rod is provided with a fixing slot. The telescopic rod is mounted with a control handle through a control rod and a fixing slot. A reaction beaker (4) is placed in the placement slot. USE - Reaction device for preparing graphene (claimed). ADVANTAGE - The reaction device facilitates the adjustment of the height of the reaction plate and operation of the user. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the reaction device for preparing graphene.
