    摘要： An adjustable length golf club including an engaging mechanism, a rotational shaft, a locking mechanism, and a lower shaft. The rotational shaft is connected with the engaging mechanism and is configured to rotate upon movement by the engaging mechanism. The locking mechanism is connected with the rotational shaft and includes a locking insert and a locking collar located on the locking insert. The locking insert being is configured to retain the locking collar during axial movement. The lower shaft has an inner surface that is in frictional contact with the locking collar. The locking insert is threadingly engaged with the locking collar and a first rotational movement in a first rotational direction by the rotational shaft causes the locking insert to move the locking collar creating a frictional locking engagement between the locking collar and the inner surface of the lower shaft.
