ABSTRACT:
A golf trolley includes a stationary tube and a push tube which has one end connected pivotally to the stationary tube. A locking device includes an engaging bolt provided on the stationary tube and a lock casing which is provided on the push tube and which has a blind bore to receive the engaging bolt therein. A press member extends through the lock casing. When the push tube is pivoted relative to the stationary tube so as to place the push tube in a substantially parallel position with respect to the stationary tube, the engaging bolt extends into the blind bore of the lock casing, and the press member locks the engaging bolt in the blind bore of the lock casing.
