[0002] In the existing fields of medical testing and biochemical experiments, it is often necessary to perform various operations on tubing (including sampling tubes) that store large quantities of liquid samples, such as opening caps and moving them. In such processes, it is necessary to clamp and fix the tubing.

[0003] Current pipe clamping and fixing devices, such as the pipe clamping device disclosed in CN105014165A and CN103419152A, are all designed for clamping single test tubes or a small number of test tubes and are not suitable for clamping large batches of pipes that are distributed in an array.

[0004] Therefore, existing equipment can perform clamping operations on single tubes or multiple tubes, but it is difficult to achieve synchronous clamping for large batches of arrayed tubes.
