AI Technical Summary
Existing shakers may cause the tube stopper to loosen during test tube shaking, resulting in sample spillage, which affects the mixing effect and experimental accuracy.
A medical testing sample oscillation device was designed. Through the cooperation of a pressure plate, a slider, a spring, and a slide, the spring provides a pushing force to maintain stable contact between the tube plug and the test tube. The cooperation of a limiting ring and a pull plate prevents the pressure plate from dislodging from the tube plug. Combined with a power mechanism, the corrugated plate is driven to generate oscillation force, ensuring that the sample in the test tube is uniformly mixed.
This effectively prevents the stopper from detaching from the test tube, improves the stability of the stopper, and ensures the uniformity of sample mixing and the accuracy of the experiment.
