The ring block 11 has a rotating groove that fits the swivel 18.

[0026] In this embodiment, by providing an oblique groove 108, and the top depth of the oblique groove 108 is greater than the bottom depth, the bevel block 15 can gradually flip the conical block 16 when it slides in the oblique groove 108, and the conical block 16 will rotate within a certain range around the rotating shaft 101 under the action of the connecting block 19 until the conical block 16 is in a vertical state, thereby continuing to squeeze the soil at the top of the borehole, which not only expands the diameter of the top of the borehole, but also makes the soil at the edge of the borehole tighter, and a threaded rod 12 and a limiting rod 13 are provided, and the threaded rod 12 can threadably drive the threaded sleeve 14, and under the restriction of the limiting rod 13, the threaded sleeve 14 can slide on the threaded rod 12, thereby adjusting the conical block 16 through the bevel block 15 and the oblique groove 108.

[0027] Example 2

[0028] like Figure 1-Figure 3 As shown, the top of the conical block 16 is fixedly connected to a connecting block 19, and a rotating shaft 101 passes through the interior of the connecting block 19, and the rotating shaft 101 is rotatably connected to the connecting block 19.

At this time, the turntable 107 is rotated. Driven by the turntable 107, the threaded rod 12 will rotate. At this time, the threaded rod 12 will threadably drive the threaded sleeve 14. Since the threaded sleeve 14 will be restricted by the limit rod 13, the threaded sleeve 14 will drive the four bevel blocks 15 to be inserted into the oblique grooves 108 opened inside the four conical blocks 16. Sliding. Due to the special shape of the oblique groove 108, when the bevel block 15 gradually slides from the top of the oblique groove 108 to the bottom, it will drive the conical block 16 to rotate. At this time, the conical block 16 will drive the connecting block 19 to rotate around the rotating shaft 101 until the conical block 16 fits into the borehole wall and gradually compresses the borehole wall and the soil at the edge, so that the diameter of the top of the borehole is slightly larger than its diameter after it goes deeper. While the threaded rod 12 rotates, the threaded rod 12 will drive the inner diameter ring of the bearing 17 to rotate, and will drive the swivel 18 to rotate in the rotating groove starting from the inside of the ring block 11, so as to ensure the stable rotation of the threaded rod 12.
