step 302, when the blood sampling test tube descends to be in contact with the mounting cylinder, the blood sampling test tube can be jacked up from the test tube clamping groove along with the continuous descending of the blood sampling test tube;
step 303, after the sealing cover at the top end of the blood sampling test tube is ejected out of the test tube clamping groove, the tube body of the blood sampling test tube in an inclined state can slide out of the test tube chuck along the test tube sliding groove;
and step 304, after the blood sampling test tube slides out of the test tube chuck, the blood sampling test tube in an inclined state can automatically fall into a test tube tray arranged around the outer side of the mounting cylinder.
10. The operating method for automatically shake-boxing blood sampling test tubes according to claim 6, wherein in step 400, the test tube boxing mechanism automatically collects blood sampling test tubes by the following specific steps:
step 401, the PLC starts a motor, the motor drives a gear on the upper surface of a rotating ring to rotate, the gear is meshed with a transmission gear on the upper surface of the rotating ring, and a belt rotates around the outer side of the mounting cylinder;
step 402, in the process of rotating the rotating ring, a push rod on the outer side of the rotating ring continuously sweeps the interior of the test tube tray, and blood sampling test tubes scattered in the test tube tray can be pushed;
step 403, can drop after the blood sampling test tube is pushed to the test tube through hole, and the user places the receiver of collecting the blood sampling test tube under the test tube through hole, is convenient for accomodate the blood sampling test tube automatically.
