A first through-hole 11 is provided in the center of the housing 1, and the sliding body 21 is slidably mounted on the first through-hole 11. Multiple connecting plates 22 and first hinge seats 23 are possible. In this embodiment, six connecting plates 22 and six first hinge seats 23 are preferably provided. The six connecting plates 22 are welded to the sliding body 21 and are evenly distributed around the sides of the sliding body 21. The six first hinge seats 23 are fixed to the six connecting plates 22 by bolts.
[0026] There can be multiple bottom expansion mechanisms 3 and connecting rods 4. In this embodiment, there are preferably six bottom expansion mechanisms 3 and connecting rods 4.
[0027] Each of the six bottom-expanding mechanisms 3 comprises an extending arm 31, a plurality of rolling cutter members 32, and a fourth hinge base 33. The rolling cutter members 32 each comprise a rolling cutter and a supporting block, and the rolling cutter is rotatably sleeved on the supporting block and provided with a convex point. The supporting blocks of the rolling cutter members 32 are respectively connected to one side of the extending arm 31 by screws, and the fourth hinge base 33 is fixedly connected to the other side of the extending arm 31 by screws.
[0028] One end of each of the six connecting rods 4 is hingedly connected to one of the six first hinge bases 23 of the sliding mechanism 2 through a pin shaft, and the other end of each of the six connecting rods 4 is hingedly connected to one of the fourth hinge bases 33 of the six bottom-expanding mechanisms 3 through a pin shaft.
[0029] The side of the shell 1 is provided with six fixed shafts, and the top of the extending arm 31 of each of the six bottom-expanding mechanisms 3 is sleeved on one of the six fixed shafts of the shell 1, so that the top of the extending arm 31 of each of the six bottom-expanding mechanisms 3 is hingedly connected to the shell 1. After being arranged, the six bottom-expanding mechanisms 3 are evenly arranged around the side of the shell 1.
[0030] The side of the shell 1 is also provided with six accommodating cavities 12, and the number of the accommodating cavities 12 is equal to the number of the oil cylinders 5. In this embodiment, the number of the accommodating cavities 12 and the number of the oil cylinders 5 are both six, and the six accommodating cavities 12 are evenly arranged on the side of the shell 1. Each of the six accommodating cavities 12 is connected with a third hinge base 13, and each of the six oil cylinders 5 is arranged in one of the six accommodating cavities 12. In each of the six accommodating cavities 12, the bottom of the cylinder body of the oil cylinder 5 is hingedly connected to the third hinge base 13 through a connecting block.
[0031] The sliding mechanism 2 further comprises a sleeve block 24, which is fixedly sleeved on the sliding body 21. The sleeve block 24 is provided with a plurality of second hinge bases 241, and the number of the second hinge bases 241 is equal to the number of the oil cylinders 5. Therefore, the number of the second hinge bases 241 and the number of the oil cylinders 5 are both six. The piston rod of each of the six oil cylinders 5 is hingedly connected to one of the six second hinge bases 241 through a pin shaft, so that all the oil cylinders 5 are connected to the sliding body 21.
[0032] The middle part of the sliding body 21 of the sliding mechanism 2 is provided with a second through hole 211, and the shell 1 is provided with a hole. The waste discharge pipe 6 is clamped on the hole, so that the waste discharge pipe 6 is fixedly connected to the shell 1.

[0036] When drilling a pile hole, the bottom expansion mechanism 3 can remain stationary. At this point, the external power unit can drive the mechanism to rotate, and the external linear motion unit can drive the mechanism forward, thereby jointly performing the pile drilling operation. When bottom expansion is required, the oil cylinder 5 can drive the sliding body 21 to move along the first through-hole 11, thereby causing the first hinges 23 connected to the sliding body 21 via the connecting plate 22 to move accordingly. The movement of the first hinges 23 can drive the bottom expansion mechanism 3 to rotate and extend about a fixed axis on the housing 1 via the connecting rod 4. At this time, the external power unit can still drive the mechanism to rotate, causing the bottom expansion mechanism 3 to rotate accordingly, and the hob 32 can grind the inner wall of the pile hole in contact with it to achieve bottom expansion.
[0037] In addition, waste materials such as sand and gravel generated during the pile hole drilling or bottom expansion process can be removed by external vacuum equipment through the waste discharge pipe 6, thereby preventing the waste materials from hindering the pile hole drilling or bottom expansion process.
[0038] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
