[0039] Further, the first side roller 3 comprises a plurality of first side rollers 3 arranged on the first clamping arm 1, the plurality of first side rollers 3 are arranged side by side along the extension direction of the first clamping arm 1, and the rotating shafts of the plurality of first side rollers 3 are arranged in parallel with each other.

[0040] Further, one first side roller 3 is arranged at a position protruding from the end surface of the first clamping arm 1.

[0041] Further, the second side roller 4 is provided on the second clamping arm 2, a plurality of the second side roller 4 is arranged side by side along the extension direction of the second clamping arm 2, and the rotation axes of the plurality of the second side roller 4 are arranged parallel to each other, and the plurality of the first side roller 3 and the plurality of the second side roller 4 are arranged one by one.

[0042] Further, one of the second side roller 4 close to the end surface of the second clamping arm 2 is arranged protruding from the position of the end surface of the second clamping arm 2.

[0043] Specifically, the first side roller 3 and the second side roller 4 are arranged as a plurality of side by side, which can increase the extrusion effect on the sponge, and the effect of extracting the sponge adsorbed liquid in the test tube is better and the efficiency is higher, and the positions of the first side roller 3 and the second side roller 4 relative to the first clamping arm 1 and the second clamping arm 2 are located at the most front end of the position of clamping the sponge, which can directly clamp the sponge through the first side roller 3 and the second side roller 4, so as to more conveniently clamp the sponge and directly implement the subsequent liquid extrusion operation on the sponge, so that the device is more convenient to use.

[0044] Further, the driving mechanism comprises a guide pipe 5, a driving rod 6, a driving gear 7 and a driving rack 8;
