Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1Geotechnical engineering investigation is a necessary procedure for construction projects. It is to find out the engineering geological conditions and hydrogeological conditions such as the site and foundation, and provide a geological basis for the design of engineering construction. In the process of geotechnical engineering investigation, a sampling mechanism is usually required to sample and study the soil at the construction site. The utility model provides a technical solution: a portable sampling mechanism for geotechnical engineering investigation, including a base 1, two rollers 9 are symmetrically arranged on the right side of the base 1, a handle 10 is arranged on the right side of the top of the base 1, and an anti-slip pad is arranged on the surface of the handle 10. By tilting the base 1, the roller 9 is made to abut against the ground, and the mechanism can be pushed to move with the cooperation of the handle 10, thereby improving the portability.

[0019] In this embodiment, please refer to Figure 1 and Figure 2 The top of the base 1 is provided with sliding rods 2 on both sides, and a fixed seat 3 is jointly provided on the top of the two sliding rods 2. The outer walls of the two sliding rods 2 are jointly sleeved with a movable seat 4. The sliding rod 2 is slidably connected with the movable seat 4. A screw rod 5 is provided at the bottom of the fixed seat 3. The bottom of the screw rod 5 passes through the movable seat 4, and the screw rod 5 is threadedly connected with the movable seat 4.
