The present invention provides an improved club of the type that includes a main rod 1, an auxiliary rod 2, and an extension rod 3. The engagement between the main rod 1 and the auxiliary rod 2 is facilitated by the threaded collar 11 of the main rod 1 and the threaded sleeve 25 of the auxiliary rod 2. One end of the auxiliary rod 2 is provided with a fastening collar 24 and an expanding socket 21. By the axial movement of the threaded sleeve 25 and the auxiliary rod 2, the length of the auxiliary rod 2 can be adjusted. On the other hand, the junction between the auxiliary rod 2 and the extension rod 3 is provided with zigzag or taper or polygonal shape end with which the extension rod 3 can be fixedly adjusted respect to the auxiliary rod 2. By this arrangement, the overall length of the club can be readily and conveniently adjusted according to the height of the user. On the other hand, when the club is not in use, the main rod 1, auxiliary rod 2, and the extension rod 3 can be readily retracted to each other to reduce the overall length when not in use.
