A sampling tool for experiments

Abstract

This utility model discloses a sampling tool for experiments, belonging to the field of sampling tools. It includes test tube A, with a retaining ring fixedly connected to its outer surface. Test tube B is fixedly connected inside the retaining ring, and an adjustment mechanism is fixedly connected to the bottom of test tube B. A locking mechanism is fixedly connected to the outer surfaces of test tubes A and B. The adjustment mechanism includes a telescopic tube, with one end of the telescopic tube fixedly connected to the bottom of test tube B. Through the coordinated use of these devices and the adjustment mechanism, samples at different heights and positions can be extracted simultaneously. Sampling at different heights and positions allows for a more comprehensive reflection of the sample's true condition, reduces sampling bias, ensures sample representativeness, and provides richer data for more comprehensive and in-depth analysis, improving the accuracy of sample testing.
