发明名称 Turf repair apparatus
摘要 An apparatus for removing ball marks from golf course surfaces includes an elongated handle having at one end thereof a tongue having prongs to be inserted into the turf, adjacent and beneath the ball mark. A tension spring attaches the tongue to the handle, and a compression spring spaces the tongue from the handle against the action of the tension spring. The tension spring attachment permits the tongue to pivot relative to the long axis of the handle, and the compression spring acts to return the tongue to alignment with the long axis of the handle after each use.
