Although the existing technical problems have been solved, the following problems still exist:

[0004] In this technical solution, after drilling a hole, it is necessary to loosen the fixation on the shaft disc, and then adjust the shaft disc to the second hole position facing the drill bit and then fix the shaft disc again. And so on. The more holes there are, the more adjustments are required. This is not only troublesome to operate, but also easily causes the hole position to be inaccurate. Therefore, improvements are made to address this problem. Utility Model Content
