After adopting above-mentioned structure, this embodiment beneficial effect does:

1. the first drilling support 12-6 at the front side and the rear side is moved and adjusted by taking the first drilling support 12-6 in the middle as a center, so that the distance between the three drill bits is changed, the drilling requirements under different conditions are met, and the drilling efficiency can be improved;

2. the chips generated after drilling are collected in a centralized manner through the collecting frame 8, so that the chips generated during drilling are prevented from being splashed;

3. the collection frame 8 can be taken out, so that the fragments in the collection frame 8 can be conveniently subjected to post-treatment;

4. the workpiece is clamped through the clamping block 7-5, so that the workpiece is more stable in machining, and chips generated by machining and drilling fall from the adjusting groove 7-1-1.

The second embodiment is as follows:

referring to fig. 5-7, the present embodiment differs from the first embodiment in that: the horizontal drilling mechanism 12 is replaced by a circumferential drilling mechanism 16, and the circumferential drilling mechanism 16 comprises:
