[0002] The methylation gene preparation workstation usually refers to the laboratory equipment and operating platform used for DNA methylation analysis in molecular biology research, of which the sample mixing workbench is an important component;

[0003] At present, when preparing samples, the methylation gene preparation workstation needs to be shaken by a stirring workbench. The current shaking method is basically to design an adapter seat at the bottom of the sampling tube, and drive the sampling tube to rotate through a driving mechanism to complete the shaking work. After the sample is shaken, it is necessary to manually discharge the shaken sample. If the discharge operation is not standardized, it is easy to affect the sample quality;

[0004] Therefore, it is necessary to propose a collection tube stirring and piercing workbench to automatically complete the shaking of the sample, pierce the collection tube after shaking, and discharge the sample into a corresponding container to facilitate subsequent work. Summary of the invention

[0143] After the storage vessel 222C is switched, the switching driving member moves to complete the storage vessel 222C to press against the one-way valve 232G and continue to move upward. At this time, the storage vessel 222C presses against the force-bearing part 232G4 to drive the valve body 232G2 to rise, and the discharge port 232G1 contacts the sample stored inside the tube body 232A. The sample is filtered through the filter cartridge 232E, passes through the discharge port 232G1 and the discharge channel 232G3, and is discharged into the storage vessel 222C. When the sample is discharged, the shaking and lifting motor 251 drives the shaking and lifting screw rod 252 to move, and drives the shaking and lifting frame 253 to continue to descend along the shaking slide rail, so that the shaking rod 255C3 drives the piston body 232C to descend in the piston cylinder 232D through the extrusion through hole, thereby accelerating the discharge speed of the sample.
