The first elastic member is a first compression spring 33, which is sleeved on the column 1, and the two ends of the first compression spring 33 are respectively tightly arranged on the limiting member and the sliding sleeve 31. A support tube 311 and a telescopic rod 312 are arranged on the sliding sleeve 31, the axis of the support tube 311 is perpendicular to the axis of the sliding sleeve 31, one end of the support tube 311 is fixed to the sliding sleeve 31, and the other end of the support tube 311 extends toward the end away from the sliding sleeve 31, and one side of the telescopic rod 312 coaxially extends into the support tube 311. The hinge rod 34 is located at the lower side of the sliding sleeve 31, one end of the hinge rod 34 is hinged to the column 1, and the other end of the hinge rod 34 is hinged to the end of the telescopic rod 312 away from the column 1. In addition, at least three support tubes 311 are evenly spaced around the axis of the sliding sleeve 31, and both the telescopic rod 312 and the hinge rod 34 correspond to the support tubes 311 one by one.

[0039] In order to reduce the situation where the ends of the telescopic rod 312 or the hinged rod 34 abut against the side wall of the pile hole and wear, a ball 313 is embedded in the end of the telescopic rod 312 away from the column 1, and the side of the ball 313 away from the telescopic rod 312 is located on the outside of the hinged rod 34 and is used to abut against the side wall of the pile hole.

[0040] Next, referring to the figure, the detection component 4 includes a fixed cylinder 41, a detection rod 42 and a second elastic member. The axis of the fixed cylinder 41 is perpendicular to the axis of the column 1, one end of the fixed cylinder 41 is fixed on the column 1, and the other end of the fixed cylinder 41 extends toward the side away from the fixed cylinder 41.
