Four guide grooves 9 are provided with thread grooves on one side close to the synchronous control thread 19, and the four guide grooves 9 are respectively meshed and connected with the synchronous control thread 19 of the control disk 8 through the thread grooves. An adjusting shaft 12 is provided in the middle of the side of the control disk 8 close to the clamping adjustment seat 3, and an adjusting groove is provided at the center of one side of the clamping adjustment seat 3. One side of the adjusting shaft 12 is inserted into the adjusting groove and sleeved with a driven bevel gear 13.

A conveying shaft of the driving box 5 is provided with a driving bevel gear 14 inserted into the adjusting groove, and one side of the driving bevel gear 14 is meshed and connected with the driven bevel gear 13.

[0027] When the adaptable clamping seat 2 is in a horizontal posture and is in a drilling processing state, when the adaptable clamping seat 2 is provided with a side of the clamping block 10 facing upward, the flange 11 can be intermittently fed by the vertical feeding device, so that the clamping block 10 clamps the flange 11, and when the adaptable clamping seat 2 is provided with a side of the clamping block 10 facing downward, the clamping block 10 can be retracted to allow the flange 11 to fall naturally;
