[0035] 1. In the present invention, multiple groups of magnetic sampling mechanisms are inserted into multiple card slots of a turntable component, and the negative pressure generated by the electromagnet triggering the magnetic sampling mechanism sucks the sample into the magnetic sampling mechanism. The single-axis driving mechanism drives the electromagnet to slide in the circular hole, so that the magnetic sampling mechanism containing the sample can be sucked out of the card slot and transported to the outside of the main body. The magnetic sampling mechanism is inserted into the sample placement slot for storage, and the rotating motor drives the turntable component to rotate, and a new magnetic sampling mechanism is sent to the circular hole, and a new round of sampling operation can be performed, thereby achieving continuous sampling operations without removing the main body from the sample, so that the sampling device has strong functionality and high sampling efficiency.

[0036] 2. In the present invention, the rotation of the servo motor drives the lead screw to rotate, and due to the screw connection between the lead screw and the slider, the slider is driven to slide along the slide rail, thereby driving the electromagnet to move in the circular hole, so as to drive the magnetic sampling mechanism magnetically adsorbed by the electromagnet to detach from the card slot and enter the circular hole after sampling is completed, thereby completing the sampling and facilitating the transportation of the randomly selected samples.

[0037] 3. In the present invention, the magnetic attraction part is attracted by the electromagnet, and the piston part is driven to slide in the piston groove when the magnetic attraction part approaches the electromagnet, so that the negative pressure generated in the piston groove acts on the liquid inlet and the liquid inlet hole from the flow channel and the annular groove, and the sample enters the annular groove through the liquid inlet hole and the liquid inlet for storage. The structural design is ingenious, which is convenient for sample extraction and also convenient for linkage between the movement of the sample storage block and the electromagnet.
