When the screw 902 rotates and drives the threaded sleeve 903 to rotate and move downward, the connecting rod 904 is limited by the slideway 13, and then the threaded sleeve 903 is limited by the connecting rod 904, so that the threaded sleeve 903 can only move vertically up and down, so that the threaded sleeve 903 drives the connecting rod 904 to move up and down, and then the connecting rod 904 drives the drilling motor 10 to move up and down, thereby completing the drilling process of the flange.

[0026] like Figure 1-5As shown, the limiting assembly 4 includes a pillar 401 fixedly connected to the center of the upper end of the turntable 3, the outer wall of the pillar 401 is fixedly connected with three slide cylinders 402, and the three slide cylinders 402 are arranged in a ring on the outer wall of the pillar 401.

[0028] In this embodiment, when in use, the three one-third threaded rings 405 on the outside of the pillar 401 are pressed to make the one-third threaded ring 405 move toward the pillar 401, and then the one-third threaded ring 405 drives the inner part of the sliding cylinder 402 under the sliding rod 403 to slide toward the pillar 401, and at the same time, the spring 404 begins to shrink under the drive of the one-third threaded ring 405. At this time, the threaded ring at the center position of the flange that needs to be drilled is threadedly fixed with the one-third threaded ring 405, so that the three one-third threaded rings 405 and the threaded rings opened at the center of the flange are fixed, and then the electric telescopic rods 502 in the annular array above the turntable 3 are controlled to make the three electric telescopic rods 502 move toward the flange at the center at the same time, and the three electric telescopic rods 502 simultaneously drive the one-third stabilizing ring 503 to move toward the flange at the center, so that the inner walls of the three one-third stabilizing rings 503 are tightly fitted with the outer side of the flange at the same time, thereby fixing the flange.
