The device has four sets of rotating rods evenly arranged inside the mounting shell, so that when in use, four sets of drill bits can be installed at the same time, thereby improving the drilling efficiency and saving drilling time during drilling. The limiting block set at the output end of the electric cylinder effectively improves the stability of the mounting shell during drilling, thereby improving the accuracy of drilling.
