Anti-pollution batch test tube uncovering structure

The invention discloses an anti-pollution batch test tube cover opening structure which comprises a cover screwing head, a test tube cover lifting mechanism and a cover screwing driving mechanism. The anti-pollution batch test tube cover opening structure is suitable for cover opening operation of batch test tubes, synchronous and same-direction rotation of the multiple cover screwing heads can be achieved through single-time operation of the cover screwing driving mechanism, so that synchronous unscrewing of batch test tube covers is achieved, and the unscrewed test tube covers are lifted through cooperation with the test tube cover lifting mechanism; therefore, synchronous uncovering of the test tubes is realized, and the problems of low working efficiency and easy neglected loading and wrong loading caused by the fact that laboratory detection personnel need to unscrew the covers of the test tubes by one hand for thousands of times every day are solved. Meanwhile, the test tube covers are opened through th
