Soil sampler refers to a tool used to obtain soil samples. In the investigation of environmental geology, it is necessary to sample the soil, and then a soil sampler is needed.

[0003] According to the "A Soil Sampler for Environmental Geological Survey" disclosed in Chinese Patent Publication No. CN214224612U, the device includes a sampling test tube; the inner wall of the top of the sampling test tube is processed with a circular connecting hole; the inner wall of one side of the sampling test tube is processed with a hollow connecting groove; the inner wall of the bottom end of the sampling test tube is processed with a square connecting hole; the inner wall of one side of the sampling test tube is processed with a sliding connecting groove; the sliding connecting groove and the square connecting hole are interconnected; the inner wall of one side of the sampling test tube is fixedly connected with a load-bearing link by screws; the inner wall of one side of the load-bearing link is connected with evenly distributed sliding connecting grooves by hinges; one side of the inner wall is slidably connected with a supporting slider; the outer wall of one side of the supporting slider is rotatably connected with a rotating connecting rod; the outer wall of one side of the rotating connecting rod is rotatably connected to the outer wall of one side of the arc baffle.
