9. The successive sample tube supply mechanism according to claim 8, wherein the stop assembly (3) further comprises a stop reset sensor (38), the cover plate (33) extends downward to form a connecting block, the stop reset sensor (38) is detachably connected to the connecting block and located at one end of the first stop plate (31) far away from the chute assembly, a clamping groove (381) is formed in the stop reset sensor (38), and one end of the first stop plate (31) far away from the chute assembly can extend into the clamping groove (381).
10. The method for supplying a sample tube sequential supply mechanism according to any one of claims 1 to 9, comprising the steps of:
s1: in an initial state, the first baffle (31) is retracted, the second baffle (32) is extended, and the chute assembly sequentially conveys a plurality of sample tubes (2);
s2: when the bar code needs to be pasted, the first baffle (31) extends out, the second baffle (32) retracts, and the sample tube (2) slides out of the second baffle (31);
s3: when the sample tube (2) slides out of the second baffle (32), the first baffle (31) is retracted, and the second baffle (32) extends out, so that the sample tube slides in between the first baffle (31) and the second baffle (32) again;
s4: steps S1 to S3 are repeated until all sample tubes (2) are bar-coded.
