[0046] Embodiment 2:

[0047] As attached Figure 2 To Attachment Figure 6 As shown:

[0048] On the basis of Example 1, the left side of the mounting ring 5 is slidably connected to the upper and lower sides with a guide slide bar 501, which is elastically connected to the mounting ring 5 through a first elastic member 502, and a positioning hook 503 is fixedly connected to the lower end face of the guide slide bar 501; the lower part of the first sampling piece 6 is slidably connected to the guide slider 601, which is elastically connected to the first sampling piece 6 through a second elastic member 603, a semi-conical sealing sheet 602 is fixedly connected to the lower part of the guide slider 601, and a traction rope 604 is fixedly connected to the outer side of the guide slider 601.

[0049] The specific usage and function of this embodiment are as follows: when sampling, the electric telescopic rod 4 is started, so that the piston rod of the electric telescopic rod 4 pushes the first sampling piece 6 and the second sampling piece 7 to move downward, and the pH value, moisture, temperature, etc. of the soil are detected by the sensor sensing points on the first sampling piece 6 and the second sampling piece 7.

At this time, the second elastic piece 603 can push the guide slider 601 to reset, and the first elastic piece 502 drives the guide slide bar 501 to reset and retract into the mounting ring 5. When the guide slider 601 is reset, it drives the sealing sheet 602 to reset and block the lower part of the second sampling piece 7 to put the soil in a closed environment. When the sample needs to be taken out, the first sampling piece 6 and the second sampling piece 7 are rotated to separate the first sampling piece 6 and the second sampling piece 7 from the electric telescopic rod 4. At this time, the second sampling piece 7 can be pulled apart by force to separate the first sampling piece 6 and the second sampling piece 7, so as to facilitate the removal of the soil sample.
