▎ 摘　　要

NOVELTY - The device has a cooling chamber (1) whose side is fixed with a fixing plate. A top portion of the fixing plate is slidingly provided with a moving plate along width direction of the cooling chamber. The fixed plate is provided with driving components for driving the moving plate to rise and fall. The moving plate is close to a side surface of a cooling chamber. A moving rod is installed in the cooling cavity along the width direction. A top surface of the moving rod is connected with a box edge of a sample box. USE - Device. ADVANTAGE - The device reduces the probability of the working staff of the gas in the cooling chamber with a certain heat, and realizes continuous growth of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the device. Cooling chamber (1)
