4. The sample tube clamping device of claim 2, wherein said first clamping portion is rotatably coupled to said first holder and said second clamping portion is rotatably coupled to said second holder; at least one of the first and second clamping portions is a wheel-like structure.
5. The sample tube gripping device of claim 4, further comprising:
the second driving piece is arranged on the first bracket, connected with the first clamping part and used for driving the first clamping part to rotate so as to enable the sample tube abutted between the first clamping part and the second clamping part to rotate; or the second driving piece is mounted on the second support and connected with the second clamping portion, and is used for driving the second clamping portion to rotate so as to enable the sample tube abutted between the first clamping portion and the second clamping portion to rotate.
6. The sample tube clamping device according to claim 2, wherein the transmission assembly further comprises a transmission gear, the first transmission member and the second transmission member are in a rack structure engaged with the transmission gear, the first transmission member and the second transmission member are arranged in parallel, the transmission gear is located between the first transmission member and the second transmission member, and the first driving member is connected with the transmission gear to drive the transmission gear to rotate, so as to drive the first transmission member and the second transmission member to move relatively.
7. The sample tube clamping device of claim 2, wherein the clamping mechanism further comprises a buffer mounted to the second support and coupled to the second clamping portion, the buffer configured to be squeezed to elastically contract in a direction away from the first clamping portion when the first driving member drives the first clamping portion and the second clamping portion relatively closer to clamp the sample tube.
8. The sample tube holding device according to claim 2, further comprising a base, wherein a slide rail is mounted on the base, a first slide block is mounted on the first bracket or the first transmission member, a second slide block is mounted on the second bracket or the second transmission member, and the first slide block and the second slide block are slidably connected to the slide rail and are spaced apart from each other along an extending direction of the slide rail.
9. A scanning apparatus comprising a sample tube holding device according to any one of claims 1 to 8 and a scanning device mounted on a side of the sample tube holding device, the scanning device being configured to scan a sample tube held by the sample tube holding device to read information.
10. A liquid-based sheet producing apparatus comprising the scanning device according to claim 9.
