As one implementation mode of the invention, the clamping pieces 4 are plate-shaped objects, and the surfaces of the two clamping pieces 4 close to each other are corrugated surfaces, and the peaks and the troughs of the corrugated surfaces on the two clamping pieces 4 are in one-to-one correspondence;
When the reaction bag 2 is clamped by the two clamping pieces 4, the two clamping pieces 4 are close to each other, and the surfaces of the two clamping pieces 4 close to each other are corrugated surfaces, and the wave crest of the corrugated surface on one clamping piece 4 is aligned with the wave crest of the corrugated surface on the other clamping piece 4, so that the clamped part of the reaction bag 2 is in a corrugated clamping state from the side after the reaction bag 2 is clamped by the two clamping pieces 4, and compared with the original straight and flat clamping state, the corrugated clamping state has better isolation effect on the upper cavity and the lower cavity, further, streaming of liquid in the upper cavity and the lower cavity cannot be realized, and meanwhile, the upper liquid cannot flow to the lower liquid through the two clamping pieces 4.
