发明名称 Golf putting practice device
摘要 A putting practice device preferably includes a body and an extension. The body preferably has a concave surface for receiving a forearm or wrist. The extension can be coplanar with the body and extends away from the body. At least one receiving hole is defined by the body or extension. A golf tee partially passes through the receiving hole and is partially inserted into a top end of a putter. The device optionally includes a flange surrounding the periphery of the body and extension and a center section surrounding the receiving holes. The flange and center section can have a thickness greater than the thickness of the body and extension.
