The mounting cylinder 12 is fitted onto the sleeve 1 and threadedly fixed to the sleeve 1. Then, the fixing nails 14 are inserted into the soil to sample the soil.

[0028] Working principle: In use, first, the mounting sleeve 12 is fitted onto the sleeve 1 and threadedly fixed to the sleeve 1, abutting against the limiting ring 11. Then, the slider 15 is fitted onto the first connecting rod 2. Next, the threaded rod 19 is rotated into another through groove 18. Then, the butterfly collar 20 is rotated so that one end abuts against one of the fixing blocks 17, thereby installing the slider 15 onto the first connecting rod 2. Then, the bottom groove 7 of the connecting block 6 is aligned with the cross block 5 and connected, so that the collar 8 is fitted onto the second connecting rod 3. Finally, the handrail 10 is installed onto the second connecting rod 3 using bolts 9. After completing the installation of the device, insert the fixing nail 14 into the soil, hold the handle 10 and step on the foot pedal 16 to make the first connecting rod 2 slide into the inside of the sleeve 1, and then drive the sampling cylinder 4 to extend from the bottom of the sleeve 1 into the soil to carry out sampling.
