[0002] The technical field of screening sampling devices refers to the field of using various technical means to monitor, sample, analyze and evaluate pollutants, harmful gases, water quality, soil and other factors in the environment, so as to help us understand the pollution situation in the environment. Soil heavy metal screening sampling devices are often used in the technical field of screening sampling devices to collect soil samples and ensure that the sample collection process is not affected by external pollution. During the collection process, ensure that appropriate sampling points and depths are selected to representatively reflect the distribution of heavy metals in the soil. This is very important for screening sampling devices and soil pollution assessment.

[0003] At present, when the existing screening sampling device is in use, the soil in some areas may be relatively loose during sampling. When the staff is working, it may be necessary to fix the equipment by manual pressing. When the staff presses at an inappropriate angle or method, it may cause the equipment to move or shake, which to a certain extent reduces the stability and work efficiency of the equipment; when the existing screening sampling device is in use, when sampling soil at different depths, it may be necessary to perform manual shoveling or prepare sampling drills of different sizes. The above operations are relatively cumbersome, which to a certain extent reduces the applicability and convenience of the equipment. Therefore, there is an urgent need for a soil heavy metal screening sampling device to solve the above problems. Utility Model Content

[0029] Example 2

[0030] like Figure 5 As shown, based on the same concept as the above embodiment, this embodiment further proposes that: the outer surface of the upper end of the support frame 1 is fixedly connected to a rotating structure 6, and the bottom end portion of the outer surface of the upper end of the support frame 1 is fixedly connected to a telescopic structure 7, and the position of the rotating structure 6 corresponds to the position of the telescopic structure 7.
