At this time, the staff inserts the sealed sampler into the food to be tested, and then presses one end of the second pressing plate 16 to make the second limiting column 18 slide out from the limiting hole 19 on the opposite side. The second limiting post 18 is inserted into the limiting hole 19 at this time, and the food to be sampled enters the sampling chamber. After the sampling is completed, one end of the second pressing plate 16 is pressed to make the second limiting post 18 slide out from the limiting hole 19.
