[0015] The principle and beneficial effects of this technical solution: (1) The sampling assembly provided in the present invention can be used to obtain tumor cell samples at a specified depth. The lock of the control assembly on the safety assembly is released, and the first sampling needle and the second sampling needle are respectively controlled by the control assembly to pop out in sequence, so that the sample can be taken and stored in the sampling slot opened at the top of the first sampling needle. At this time, the pump connected to the sample collecting tube is started, and the sample in the sampling slot can be sucked from the multiple collecting slots opened at one end of the sample collecting tube through the pump. The sample will enter the sample tube in the rotating drum through the through groove. After completing one suction, the push block is manually pushed back to make the second sampling needle pop out of the handle to complete the second sample cutting. At the same time, during the backward movement of the push block, the sliding button connected to the soft bracket will slide along the straight groove, so that the rotating drum where the inclined groove is located will rotate along the clamping cylinder at the bottom end of the handle. When the rotating drum rotates, the sample tube connected to the bottom end of the sample collecting tube will be switched, so that a new round of samples will be collected by the new sample collecting tube.

[0016] (2) The control assembly provided in the present invention can control the ejection of the first sampling needle and the second sampling needle respectively. When sampling is required, the lock of the control assembly by the safety assembly is first released, and then the two pressure plates are pressed in sequence, and the pressure plate will move down along the groove. At the same time, the pressure plate will drive the sliding plate and the limit hook connected to its bottom end to move down and compress the spring connected to its bottom end. After the limit cylinder connected to the sliding plate moves to align with the notch opened at the bottom end of the side plate, the first sampling needle and the second sampling needle will move forward respectively under the elastic force of the compression spring and the tension spring until one side of the side plate contacts one side of the sliding plate.
[0017] (3) The safety assembly provided in the present invention can lock the position of the pressure plate in the control assembly to prevent the first sampling needle and the second sampling needle from being ejected due to accidental touch. When it is necessary to release the position lock of the pressure plate by the safety assembly, the safety block is slid outward so that the magnetic block connected to the free end of the safety block is attracted to the outer side of the handle. At this time, the limit block connected to the safety block through the connecting frame will move outward synchronously so that the limit block no longer contacts the bottom end of the limit hook. At this time, the pressure plate where the limit hook is located can be moved downward. BRIEF DESCRIPTION OF THE DRAWINGS
