The present invention has the following effects: by rotating the rotating wheel clockwise, the horizontal axis can be driven to rotate synchronously, and the left rod clamping frame and the right rod clamping frame can be driven to move toward the center position of the drilling platform at the same time. Under the synchronous thrust of the left rod clamping frame and the right rod clamping frame, the fixed rod is always located at the center position of the drilling platform. Because the structure of the rod limit seat is rotatable, the fixing mode of the rod can be changed by rotating the rod limit seat, so that the rod can be stably positioned when drilling the axial center or the side center, and the axial center or the side center of the fixed rod can be aligned with the drill bit above, so as to quickly drill the axial center and the side center of the small diameter rod in a timely and efficient manner;
