[0043] The utility model has the advantages of slowly driving the piston 307 to move in the sampling barrel 301 when the screw is screwed, and slowly extracting or pushing out the sample liquid of the cosmetics in a controllable amount, by arranging the sampling barrel 301, the sampling head 302, the sealing block 303, the threaded rod 304, the rotating handle 305, the connecting block 306 and the piston 307, thereby solving the problem that the pushing force is difficult to control when injecting the sample, resulting in the difficult control of the amount of medicine injected into the detector.

[0044] Specifically, a transparent acrylic plate is embedded in the opening of the outer wall of the sampling tube 301, and a scale is engraved on the acrylic plate, through which the amount of the sample liquid can be observed.

[0045] Furthermore, two positioning blocks 308 are symmetrically fixed on the outer wall of the sealing block 303 , and the positioning blocks 308 are fixedly connected to the outer wall of the outer end of the sampling tube 301 through screws 309 , and the screws 309 pass through the holes on the positioning blocks 308 and are screwed into the screw holes on the outer wall of the outer end of the sampling tube 301 .

[0047] Furthermore, the positioning block 308 is configured to be arc-shaped, and the inner side of the positioning block 308 contacts and cooperates with the outer wall of the outer end of the sampling tube 301. The positioning block 308 fits the outer wall of the outer end of the sampling tube 301, and is more stable after installation and positioning.

[0048] It is worth noting that a support structure 2 is arranged on one side of the shell of the heavy metal detector body 1;
