The middle part of the pushing cross rod 5 is provided with a positioning hole 6, so that the manual control rod 3 can penetrate through the positioning hole to perform vertical movement positioning on the manual control rod 3.

The outer diameter of the upper fixed cylinder 2 is smaller than the inner diameter of the adjustable depth sampling cylinder 1.

The upper fixed barrel 2 is arranged above the sampling barrel 1 with adjustable depth in an adjustable height way through a connecting piece. The connecting piece comprises a positioning rod 6 and a reinforcing rod 9. The stiffener 9 is fixed at the up end of the upper portion fixed cylinder 2 in the shape of a scroll, and length is no longer than the outer wall of the upper portion fixed cylinder 2, and the up end at the upper portion fixed cylinder 2 is fixed respectively at the both ends of locating lever 6, and the both ends of locating lever 6 are equipped with sleeve pipe 8 that cup joints on vertical propulsion pole 4 respectively.

The hand control rod 3 penetrates through the positioning hole 6, the upper end of the hand control rod is provided with a handle 11, the lower end of the hand control rod is connected to the center of the positioning rod 6, and the hand control rod 3 can freely move up and down through the positioning hole 6.

As a preferred technical scheme, the lower end of the vertical push rod 4 is fixed on the upper end surface of the adjustable-depth sampling tube 1, so that the vertical push rod 4 can not additionally increase sampling resistance when the adjustable-depth sampling tube 1 is inserted into solid materials.

As another preferred technical scheme, the bottom end face of the adjustable depth sampling tube 1 is provided with a pointed cone 10, so that after the required sampling depth is reached, the adjustable depth sampling tube 1 is rotated, the separation of the adjustable depth sampling tube 1 from the solid material is facilitated, and the adjustable depth sampling tube 1 is taken out of the solid material conveniently.

The use method of the utility model is demonstrated (taking soil sampling as an example for demonstration):

inserting the depth-adjustable sampling cylinder 1 into soil, applying a downward force to the pushing cross rod 5 to gradually insert the depth-adjustable sampling cylinder 1 into the soil, and keeping the depth-adjustable sampling cylinder 1 vertical as much as possible in the insertion process; after the sampling cylinder 1 with the adjustable depth is inserted to the required sampling depth, a downward acting force is applied to the handle 11 until the upper fixing cylinder 2 is inserted into the soil, and the lower end faces of the positioning rod 7 and the reinforcing rod 9 are in contact with the surface layer of the soil; the pushing cross rod 5 is held tightly by two hands, the adjustable depth sampling cylinder 1 is rotated, and under the cutting action of the pointed cone 10, the rotation of the adjustable depth sampling cylinder 1 is combined, so that a fault is formed on the bottom end face of the adjustable depth sampling cylinder 1 by soil; the pushing cross rod 5 is pulled by two hands, the adjustable depth sampling cylinder 1 and the upper fixing cylinder 2 are pulled out from soil, clamping force is formed between the adjustable depth sampling cylinder 1 and the upper fixing cylinder 2 in the pulling-out process, and a complete cylindrical soil layer is taken out.
