In the pressure foot device 100 of the present embodiment, the base 10 is connected to a drilling actuator, and the pressing block 20 is used for pressing a thin-walled member. When the thin-wall part is pressed, as the first distance is formed between the limiting shaft 22 and the limiting hole 12, the degree of freedom in the radial direction of the drilled hole is formed between the pressing block 20 and the base 10, the pressing block 20 and the base 10 can generate relative displacement in the radial direction of the drilled hole, and the pressing block 20 can slide relative to the base 10 in the radial direction of the drilled hole, so that the thin-wall part can be prevented from being scratched, the postures of the pressure foot device 100 and the drilling actuator can be unchanged, and the drilling precision is improved. The size of the first distance can be set according to actual conditions. As shown in FIG. 2, the first pitch is (D) R -D r )/2。

When the drilling state is released, the elastic ring 30 can restore the pressing block 20 and the base 10 to the original position.
Specifically, the elastic ring 30 is a rubber ring, and it can be understood that the elastic ring 30 may also be an annular ring made of other deformable materials according to actual needs.

The displacement sensor 40 is capable of detecting a displacement on the wedge surface 52 as the compact 20 moves radially relative to the base 10 along the borehole, thereby obtaining a relative displacement between the compact 20 and the base 10. Specifically, the pressing block 20 is provided with the wedge-shaped block 50, the wedge-shaped block 50 and the pressing block 20 are connected through screws, preferably, the number of the wedge-shaped blocks 50 is four, the number of the pressing blocks 20 is two, the number of the first through holes is also four, and the two displacement sensors 40 can be in contact with the wedge-shaped surface 52 of the wedge-shaped block 50 through the two first through holes. The two displacement sensors 40 can respectively detect the relative displacement data between the two groups of pressing blocks 20 relative to the base 10, so that the relative displacement between the pressing blocks 20 relative to the base 10 can be obtained more accurately.
