[0022] The sampling tube 4 is driven to rotate on the cylinder 1 by the driving structure 5, and cooperates with the soil-breaking structure 6 to drill into the soil layer smoothly and make the soil soft, so that the detection probe 21 can be smoothly inserted into the soil, and cooperates with the control panel 3 to detect heavy metals in the soil; it is convenient and fast, and effectively reduces the workload of the staff.

[0023] In another embodiment, see Figure 1-3 The driving structure 5 includes a driving motor 51 fixed to the outer wall of the cylinder 1. A gear 52 is provided at the driving end of the driving motor 51 corresponding to the outer wall of the sampling cylinder 4. A gear ring 41 is provided on the outer wall of the sampling cylinder 4 corresponding to the gear 52, and the sampling cylinder 4 is meshed with the gear 52. A convex ring 42 is provided on the outer periphery of the top of the sampling cylinder 4.
