A feed mechanism is provided on the mounting seat, which is connected to a spindle seat, a spindle is rotatably provided on the spindle seat and a rotation driving mechanism for driving the spindle to rotate is installed. A drill bit is connected to the end of the spindle, and the spindle is driven to rotate by the rotation driving mechanism to drive the drill bit to drill the workpiece. The spindle seat is driven by the feed mechanism to move, so that the spindle seat drives the drill bit to move, so that the drill bit feeds and drills deep holes. The relative angle between the drill bit and the workpiece on the vertical plane can be adjusted by adjusting the swing direction of the mounting seat, so that the drill bit can drill the workpiece at different angles on a vertical plane.

[0003] Since the mounting base has a certain volume, it is easy to collide with the foundation when the automatic angle adjustment mechanism drives it to swing. In the related art, the bed is usually raised so that the mounting base is at a certain height to avoid collision with the foundation. However, the bed is usually made of cast iron or steel. Raising the bed will make the overall cost of the device higher. Utility Model Content
