     Preferably, as shown in  FIG. 1  to  FIG. 11 , the rotating structure  220  includes a rotating bracket  221  and the rotating bracket  221  is provided with a third rotating motor  222 , wherein an output end of the third rotating motor  222  is connected with a primary rotating shaft  223  and two auxiliary rotating shafts  224  fitting the primary rotating shaft  223  and being connected to the rotating bracket  221 , and a “tripod”-shaped structure is formed between the primary rotating shaft  223  and the two auxiliary rotating shafts  224 , and wherein the two auxiliary rotating shafts  224  are driven to rotate as the primary rotating shaft  223  rotates, so that the sample container located between the two auxiliary rotating shafts  224  rotates, and therefore, the blank region on the sample container is fully in the exposed state, and it is convenient to print patient information in the blank region by the printing mechanism  300 . 
     Further preferably, the primary rotating shaft  223  is embedded with an annular magnetic ring  225 , or the auxiliary rotating shafts  224  are embedded with annular magnetic rings  225 , or both the primary rotating shaft  223  and the auxiliary rotating shafts  224  are embedded with annular magnetic rings  225 . 
     In the embodiment, as the primary rotating shaft  223  or the auxiliary rotating shafts  224  are embedded with the annular magnetic rings  225 , an idle stroke is avoided when the primary rotating shaft  223  drives the auxiliary rotating shafts  224  to rotate, so that the rotating reliability of the sample containers is improved. 
     As shown in  FIG. 1  to  FIG. 11 , the receiving rack  210  is connected with a pushing structure  260  and the pushing structure  260  is located between the receiving trough and the stopping arm  250 , wherein two auxiliary rotating shafts  224  are separated at a relative distance via the pushing structure  260 , thereby, the printed sample containers are discharged automatically. 
     In the embodiment, by means of the pushing structure  260 , the printed sample containers located on the rotating structure  220  are discharged, and the unprinted sample containers on the receiving trough fall onto the rotating structure  220  by leaning the receiving trough against the stopping arm  250  to fit so as to form a continuous action, so that the printing working efficiency of the sample containers is improved. 
     Further preferably, the pushing structure  260  includes a U-shaped pushing bracket  261 , and two sides of the opened end of the U-shaped pushing bracket  261  are each connected with an ejector block  262 , an extension rod  2241  is respectively provided on two ends of one of the auxiliary rotating shaft  224 , and two extension rod  2241  respectively form abutting fit with the ejector block  262  on the corresponding side. 
     Further preferably, each of two sides of the rotating bracket  221  is provided with a first guide slot  2211 , and two extension rod  2241  are respectively clamped into the corresponding first guide slots  2211 . 
     In the embodiment, the rotating bracket  221  is provided with the first guide slot  2211 , so that when the ejector block  262  pushes the extension rod  2241  of auxiliary rotating shaft  224 , two ends of the auxiliary rotating shaft  224  to move along the first guide slot  2211 . The moving linearity of the auxiliary rotating shaft  224  is guaranteed, so that the printed sample containers are discharged smoothly. 
     Preferably, as shown in  FIG. 1  to  FIG. 11 , two ends of the ejector block  262  are connected to the U-shaped pushing support  261  via corresponding rotating rods  263 , the rotating rod  263  on the U-shaped pushing support  261  away from the side of the receiving trough is in clamping connection with the second guide slot  2611  in the U-shaped pushing support  261 , the rotating rod on the U-shaped pushing support  261  close to the side of the receiving trough as a fulcrum when the ejector block  262  rotates, wherein the end of the rotating rod  263  in clamping connection with the second guide slot  2611  is connected with the fixed bar  265  on the U-shaped pushing bracket  261  via the elastic piece  264 , the ejector block  262  is provided with the first working inclined plane  2621  and the second working inclined plane  2622 , a slope gradient of the first working inclined plane  2621  extends obliquely upwards from the end away from the receiving trough to the end of the receiving trough, the slope gradient of the second working inclined plane  2622  extends obliquely upwards from the end close to the receiving trough to the end of the receiving trough, and the slope gradient of the first working inclined plane  2621  is smaller than that of the second working inclined plane  2622 . 
     In the embodiment, when the pushing structure  260  is close to the rotating structure  220 , the first working inclined plane  2621  is in rolling fit with the end portion of the auxiliary rotating shaft  224 . Along with progressive increase of the slope gradient on the first working inclined plane  2621 , the auxiliary rotating shaft  224  is pushed to move along the first guide slot  2211 , and the auxiliary rotating shaft  224  generates a downward pressure to the ejector block  262  to drive the rotating rod  263  in clamping connection to the second guide slot  2611  to move along the second guide slot  2611 , since the rotating rod close to the side of the receiving trough is fixed, the rotating rod  263  away from the side of the receiving trough moves along the second guide slot  2611 , so that the ejector block  262  deflects. When the auxiliary rotating shaft  224  bestrides the second working inclined plane  2622  from the first working inclined plane  2621 , as the slope gradient of the second working inclined plane  2622  is greater than that of the first working inclined plane  2621 , rolling connection between the auxiliary rotating shaft  224  and the first working inclined plane  2621  is relieved, the auxiliary rotating shaft  224  falls back, and at the time, the completed sample containers are discharged. 
     A working principle of the multi-sample container disposal module provided by the invention is as follows: in an initial state, the unprinted sample container is mounted in the storage cavity, when a user inputs patient information such as a medical insurance card or a patient ID card, the falling wheel  170  rotates under the action of the rotating motor to fall the unprinted sample containers corresponding to the storage cavities in the falling trough  171  of the falling wheel  170 . Along with rotation of the falling wheel  170 , the unprinted sample containers fall from the falling trough  171  and enter the receiving trough below, and then the transmission motor  241  drives the lead screw  242  to rotate, so that the receiving rack  210  moves towards the discharging end till the stopping arm  250  is in contact with the ejector rod  214 ; along with continuous movement of the receiving rack  210 , the relative distance between the movable receiving plate  212  and the fixed receiving plate  211  is increased, and when the distance between the movable receiving plate  212  and the fixed receiving plate  211  is larger than the size of the unprinted sample container, the unprinted sample containers fall between the two auxiliary rotating shafts  224 , then the receiving rack  210  returns to the receiving end, and then the third rotating motor  222  drives the primary rotating shaft  223  to rotate, so that the two auxiliary rotating shafts  224  rotate, and therefore, the unprinted sample containers rotate, thereby, the blank region on the unprinted sample containers is in a fully exposed state. Finally, the patient information is printed to the blank region by the printing mechanism  300 , and then it moves towards the discharging end via the receiving rack  210 . When the ejector block  262  leans against the auxiliary rotating shaft  224 , the auxiliary rotating shaft  224  is pushed to move along the first guide slot  2211  to pull open the relative distance between the two auxiliary rotating shafts  224  so as to output the printed sample containers from the discharging plate  230 .
