The first motor 11 drives the main platform 30 to reciprocate linearly on the base 20 through a belt transmission mechanism, and the linear reciprocating direction of the main platform 30 is perpendicular to the arrangement direction (X-Y direction) of the test tubes 90 in the test tube row. The base 20 is provided with a slide bar 21, the main platform 30 is provided with a slide block 34, the slide bar 21 penetrates through the slide block 34, and when the main platform 30 moves linearly, the slide block 34 slides on the slide bar 21. In addition, a vertical plate 22 is arranged below the base 20, and a corresponding lower slider (not shown) is arranged on the main platform 30 and is connected with the vertical plate 22 in a sliding manner.

In addition, a plurality of position sensors 23 are disposed on the base 20 and aligned in a same horizontal plane, and a sensing board (not shown) is correspondingly disposed on the main platform 30, and the position sensors 23 are used for detecting the sensing board to find out the position of the main platform 30 on the base 20.

When the sampling needle 40 is driven to move up and down, the swab 33 does not follow the movement of the sampling needle 40, i.e., the sampling needle 40 moves up and down relative to the swab 33. The auxiliary platform 50 is fixedly connected with a nut 32 of the screw rod mechanism, a vertical sliding rail 31 is arranged on the main platform 30, and the auxiliary platform 50 is connected with the sliding rail 31 in a sliding mode. Therefore, when the second motor 12 rotates, the nut 32 of the screw mechanism moves up and down synchronously with the band sub platform 50 and the sampling needle 40.

sensors

52 and 53 disposed up and down, and the

sensors

52 and 53 are used for detecting the sensing plate 55 to determine the rotation position of the swing arm 51.
