发明名称 Portable golf hole cutting device
摘要 A golf hole cutting device includes an impact portion and a cutting portion. The impact portion preferably takes the form of a portable impact hammer, while the cutting portion includes a cutting head and a shaft having a terminal portion that connects with the portable impact portion. The cutting head includes a cylindrical, hollow main body portion having a first end portion which is adapted to penetrate soil and leads to a second end portion. With this construction, the impact portion is employed to deliver a series of rapid linear impacts to the terminal portion of the shaft to drive the cutting head down into soil of a putting green to form a golf hole.
