[0016] The present invention has the following beneficial effects:

[0017] 1. When the present invention is used, the staff puts the drill bit into the already drilled traction hole. When the drill bit reaches the bottom, the drill bit will push the disc to move upward. When the disc moves upward, it will push the push rod. When the push rod is pushed by the disc, it will push the slider. When the slider is pushed by the push rod, it will push the insertion rod to rotate, so that the insertion rod is inserted into the soil, so that the device can be inserted into the deep soil. At the same time, when the disc is pushed by the drill bit, it will push the hollow disc to move upward. When the hollow disc is pushed by the disc, it will push the push rod to move upward. When the push rod moves upward, it will push the Z-shaped rod to rotate. When the Z-shaped rod rotates, it will drive the two-way The connecting ear approaches the soil, and when the two-way connecting ear approaches the soil, it pushes push rod two, and when push rod two is pushed by the two-way connecting ear, it moves along the C-shaped block, and when push rod two slides along the C-shaped block, it pushes push rod three to approach the soil, and when push rod three is pushed by push rod two, it pushes the arc plate to move, and when the arc plate is pushed by push rod two, it pushes the curved plate to move toward the soil, thereby increasing the contact area between the device and the surface of the traction hole, which can enhance the stability of the device and prevent the drill bit from deviating when the device touches the rock during drilling, thereby affecting the sampling process of the device and causing errors in the survey data.

[0018] 2. In the present invention, when the curved plate is pushed outward by the push rod 2, the curved blocks at the top and bottom and the curved block 2 will be driven to move outward. When the curved block is pushed outward by the curved plate, the semicircular plate will be driven to move. When the curved block is pushed, the connecting rod will be driven to push to both sides. At the same time, the semicircular plate will slide along the curved groove. When multiple semicircular plates move at the same time, they will close to each other to block the muddy water flowing into the device. At the same time, the curved block 2 at the bottom will be pushed like the curved block to block the muddy water at the bottom. The first curved block and the second curved block will separate from each other when they are pushed. When the second curved block is separated from each other, the curved plate will be straightened. When the curved plate is straightened, the blocking plate will be pushed to block the gap between the first curved block and the second curved block pushed by the curved plate, thereby preventing muddy water from entering the device through the gap when spraying water on the working drill bit, causing particles in the mud to block components inside the equipment, resulting in equipment performance degradation or even failure, thereby affecting the sampling process of the device, and causing errors in the survey data.

[0019] 3. In the present invention, when the hollow disc is pushed by the disc, the support column will be pushed upward, and when the support column is pushed upward by the hollow disc, the push rod 4 will be pushed to rotate, and when the push rod 4 is pushed by the support column to rotate, the rack will be driven to slide, and when the push rod 4 pushes the rack to slide, the gear ring will be driven to rotate, and when the gear ring is driven by the rack to rotate, the rotating disc will be driven to rotate, and when the rack is driven by the gear ring to rotate, the connecting rod 2 will be driven to push the direction of the insertion rod 1, so that the insertion rod 1 is inserted into the inner wall of the traction hole, thereby enhancing the stability of the device. As soon as the long rod is inserted into the soil, the spring block will be squeezed by the soil and move backward. When the spring block moves backward, it will push the gas in the square groove into the gas groove. When the gas enters the gas groove, it will push the slider forward. When the slider is pushed by the gas, it will push the support rod to spread to both sides and insert into the soil, thereby increasing the contact area between the device and the soil, making the device more stable in the traction hole, thereby reducing the deviation or distortion of the device during the drilling process, further ensuring the accuracy and precision of the drilling, and making the survey data more accurate.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
