the first wheel body is driven to rotate so that the test tube clamped in the test tube clamping area rotates on the basis of the axis of the test tube;
the bar code on the test tube is acquired through a bar code scanner before the first wheel body is driven to rotate, or the bar code is acquired through the bar code scanner after the first wheel body is driven to rotate.
