[0002] An EP tube is a small centrifuge tube that can be used with a microcentrifuge for the separation of micro-reagents, freeze-drying or sample storage. It is commonly used in biochemical, medical detection and other experiments. At present, EP tubes are widely used in many laboratory experiments. However, the following problems are encountered during the use of EP tubes: 1. Frequent opening of the cover with fingers can cause hand pain or injury, and can also cause the reagent to spill out during the opening process due to excessive force; 2. Using fingers can only open one EP tube cover at a time, which is inefficient.

[0003] To solve the above problems, the patent application with the application number CN202120004296.X discloses an EP tube auxiliary cover opening device. The device can complete the opening of a row of EP tube covers in one operation. The large gear and small gear can make the opening process more labor-saving and avoid the reagent splashing phenomenon caused by opening the cover too hard.
