[0017] The utility model will be further described below in combination with the drawings and examples.

[0018] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0019] Figure 1 and Figure 2 The utility model discloses a kind of portable soil sampling device as shown in the figure, including main storage cylinder 1, three split overturn supporting plates 2 are movably assembled in the opening position of the bottom of main storage cylinder 1, internal thread limiting sleeve 3 is screwed on the upper side of split overturn supporting plate 2 assembly end on the outer side of main storage cylinder 1, internal adjusting seat 4 is slidably assembled in the inside of main storage cylinder 1, built-in material taking cylinder 5 is axially inserted in the bottom end of internal adjusting seat 4, lateral adjusting handle 6 for controlling built-in material taking cylinder 5 rotation is movably assembled on the outer side of internal adjusting seat 4.

[0020] Sampling principle: people will three split type flip support plate 2 outwardly flip out, then through the internal thread limiting sleeve 3 angle limiting, vertical on the ground, then extrude lateral adjusting handle 6, drive built-in sampling cylinder 5 insert into the soil, then pull out lateral adjusting handle 6, then rotate lateral adjusting handle 6, thereby control built-in sampling cylinder 5 synchronous rotation, so that manual sampling operation can be carried out;

[0021] When storing, only need to retract built-in sampling cylinder 5, then close three split type flip support plate 2, form a closed shell around built-in sampling cylinder 5, then move internal thread limiting sleeve 3 downward to the outside of three split type flip support plate 2, limit three split type flip support plate 2 from the outside, thereby closed and fixed.

[0022] In order to cooperate with lateral limiting, the two side walls of main storage cylinder 1 are symmetrically provided with strip-shaped guide openings 7 matched with lateral adjusting handle 6.
