[0020] (3) Through the technical solution of the utility model, the material of the flexible layer (including flexible layer 1 and flexible layer 2) is selected from elastic materials such as silicone, rubber and latex, which can adapt to the large pressure of the cover plate or the bottom plate, and can also adapt to the deformation of the shape of the mouth of the reaction bottle, thereby achieving good sealing while avoiding crushing the reaction bottle; on this basis, chemical corrosion-resistant materials such as fluororubber can be further used.
