[0012] Further, the support ring is horizontally provided with a level on each of two mutually perpendicular sides.

[0013] Further, the outer wall of the outer inserting rod is provided with a plurality of convex rings to increase the friction between the outer inserting rod and the soil and further increase the resistance of the upward movement of the outer inserting rod.

[0014] Further, the upper end face of the inner rod is provided with a slot for facilitating the rotation of the inner rod by using a screwdriver.

[0015] In the utility model, after the sampling position is determined, the outer inserting rods are driven into the soil, the support ring is adjusted to be in a horizontal state through the levels on two sides, then the inner rod is rotated by using a tool, the inner rod moves downward under the thread transmission of the outer thread section and the inner thread section, the inner rod moves downward to extrude the inner wall of the through slot section to force the outer inserting rod to expand and extrude the soil in the radial direction to increase the friction between the outer wall of the outer inserting rod and the soil to prevent the upward movement of the outer inserting rod, the drill rod and the drill bit are rotated by the motor, the threaded rod is rotated by manually rotating the hand wheel to force the sliding plate to slide downward along the stand to make the drill rod and the drill bit drill downward to a certain depth to drill the rock sample at the target depth, the support ring and the stand cannot move upward because the support rod cannot move upward, therefore the reaction force of the rock cannot make the support ring and the stand move upward when the rock sample is drilled. After the sampling is completed, the inner rod is rotated in the reverse direction to make the inner rod move upward to make the outer inserting rod shrink to reduce the friction with the extruded soil, so that the outer inserting rod can be conveniently pulled out upward.

[0016] Compared with the prior art, the utility model can realize the feeding of the drill bit by only rotating the hand wheel, the body weight does not need to be pressed to keep the feeding of the drill bit during the drilling process, and the labor intensity of the staff is greatly reduced.
