The pushing piece 32 comprises a rack 321, a gear 322, a pushing rod 323 and a coil spring 324, wherein the length of the rack 321 is larger than the height of the accommodating cavity 24, the rack 321 is slidably connected in the yielding cavity 25, the gear 322 and the coil spring 324 are arranged in the accommodating cavity 24, the gear 322 is rotationally connected in the accommodating cavity 24, one end of the coil spring 324 is fixedly connected with the gear 322, the other end is fixedly connected with the side wall of the accommodating cavity 24, which is close to the sampling cavity 21, the pushing rod 323 is a threaded rod, one end of the pushing rod 323 is in threaded connection with the gear 322, and the other end of the pushing rod 323 is connected with the baffle 211.
