[0021] Two groups of limit grooves 7 are symmetrically provided on the outer side of the support tube 5. Limit blocks 20 slidably connected to the limit grooves 7 are fixedly connected to both sides of the mounting frame 11. A guide tube 4 connected to the support tube 5 is fixedly connected to the middle part of the lower surface of the base plate 1. The limit grooves 7 improve the stability of the lifting and lowering of the mounting frame 11. At the same time, the guide tube 4 prevents soil splashing during geological exploration, thereby improving the safety of the workers during geological exploration.

[0022] An inspection door 6 is rotatably connected to the outer side of the support tube 5, and a control panel 8 is installed at one end of the upper surface of the support tube 5. The control panel 8 is electrically connected to the cylinder 9 and the motor 12 respectively.

[0023] Two groups of handles 10 are symmetrically fixedly connected to the outer upper end of the support tube 5. The two groups of handles 10 and the two groups of limit grooves 7 are vertically arranged in an offset manner. The handles 10 improve the stability of the sampling device when drilling and sampling.
