Please refer to Figure 1 , Figure 2 , Figure 3, including a pile shoe body 1, a fixed column 2 is fixedly installed at the central position of the top end of the pile shoe body 1, a connector 4 is fixedly installed at the top end of the fixed column 2, and it is connected to a drilling platform through the connector 4. A fixed ring 5 is fixedly sleeved on the outer wall of the fixed column 2. Hydraulic cylinders 6 are arranged on both the left and right sides of the fixed column 2, and the top ends of the two hydraulic cylinders 6 are fixedly connected to the fixed ring 5. The bottom ends of the two hydraulic cylinders 6 are jointly connected to a connecting ring 9, and the connecting ring 9 is movably sleeved on the outer wall of the fixed column 2. A plurality of U-shaped blocks 10 are fixedly installed on the outer wall of the connecting ring 9. Rotating shafts 11 are arranged in the U-shaped grooves of the U-shaped blocks 10. Connecting rods 12 are fixedly connected to the outer walls of the rotating shafts 11. The sides of the connecting rods 12 that are not connected to the rotating shafts 11 are all connected to second rotating shafts 13. Second U-shaped blocks 14 are connected to the outer walls of the second rotating shafts 13, and a movable fin 3 is fixedly connected to the outer wall of each of the plurality of second U-shaped blocks 14. By controlling the movement of the hydraulic cylinders 6, the connecting ring 9 can be driven to move up and down on the outer wall of the fixed column 2. At this time, the movable fin 3 can be synchronously driven to move through the connecting rod 12, and the position and angle of the movable fin 3 can be adjusted for use.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , universal swivel joints are installed at the bottom ends of the movable fins 3, and the sides of the universal swivel joints that are not connected to the movable fins 3 are all connected to the pile shoe body 1, so as to prevent the movable fins 3 from being unable to adjust their positions at the top end of the pile shoe body 1 for use.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , vertical rods 7 are arranged on both the front and back sides of the fixed column 2. Threaded limit rods 8 are arranged at the bottom ends of the vertical rods 7. Threaded grooves are arranged at the bottom ends of the vertical rods 7, and the diameter sizes of the threaded grooves are the same as the diameter sizes of the threaded limit rods 8. By previously controlling the threaded limit rods 8 to rotate downward to adjust the distance between their bottom ends and the top end of the connecting ring 9, it can be prevented that when the hydraulic cylinders 6 fail, the movable fins 3 directly rotate, resulting in too large a change in the load that the pile shoe body 1 can bear.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , a protective cover is arranged at the bottom end of the connector 4, and the protective cover is located around the connector 4, which is convenient for simply protecting the hydraulic cylinders 6.

Moreover, the connection mode between the second rotating shaft 13 and the second U-shaped block 14 is the same as the connection mode between the rotating shaft 11 and the U-shaped block 10, ensuring that the rotating shaft 11 and the second rotating shaft 13 can rotate normally.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , two plug-in grooves are provided at the bottom end of the fixed ring 5, and the diameter size of the plug-in grooves is the same as the diameter size of the vertical rod 7, which is convenient for fixing the position of the vertical rod 7 during use.

[0036] The implementation principle of this embodiment is as follows: during use, the hydraulic cylinder 6 is started by an external power source, and the hydraulic cylinder 6 drives the connection ring 9 to move up and down on the outer wall of the fixed column 2. At this time, the connection ring 9 can drive the connecting rod 12 and the movable fin 3 to move, adjust the position of the movable fin 3, and after completing the adjustment of the position of the movable fin 3, the threaded limit rod 8 can be controlled to rotate downward to fit the connection ring 9 to achieve a safety protection effect.

[0037] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
