[0002] After collecting blood samples in the blood sample tube, the blood sample in the test tube needs to be mixed. The traditional method is to mix it manually by shaking it. This method is inefficient and more importantly, operators are prone to mistakes, which can damage the blood sample. With the development of technology, people have gradually proposed to use electric methods to mix blood samples in test tubes. This electric mixing method can reduce the workload of medical staff and avoid hand muscle strain caused by long-term manual shaking of test tubes.

[0003] At present, when the electric blood sample mixing device used by the hospital laboratory is used, the test tube placed on the test tube rack needs to be transferred to the mixing device, and then the mixed test tube is placed back on the test tube rack after the mixing is completed. This operation method undoubtedly increases the operation steps and workload of medical staff, especially when there are many test tubes, which wastes time and energy and reduces the work efficiency of medical staff. In addition, the existing electric mixing device is very inconvenient to operate when fixing the test tube, especially when fixing multiple test tubes, it is often necessary to fix each test tube one by one, which is time-consuming and laborious.
