ABSTRACT:
A combination umbrella and golf ball retriever which uses the umbrella strut as a socket pipe to accommodate several telescopically nested tubes so as to form an elongated handle for a golf ball retriever. There is an eccentric-grooved stud inserted at one end of the inside tube of each two neighboring tubes. The eccentric-grooved portion of this stud matches with a similar eccentric circular bushing. When the inner tube turns to one direction, the outside part of the circular bushing will press tightly against the inner wall of the outside tube and lock up the two neighboring tubes. An opposite turn at the inner tube will set loose the circular bushing and allow both neighboring tubes to slide in and out freely so as to adjust the length of the handle of the golf ball retriever.
