Abstract
An improved golf cart mainly comprises a pair of grips, a grip-supporting-rod, a fixing seat for the grip supporting rod, an upper-fixing-member for a golf bag, a collapsible frame, a pair of wheels and a set of wheel supports. The grip can receive a golf ball and a plurality of golf tees. The upper-fixing-member for holding a golf bag can receive a plurality of golf balls. The inclination of the grip-supporting-rod is adjustable. The central components of the collapsible frame are disposed in a hollow supporting rod both to prevent the user from being hurt and to increase the component's durability. The wheels and its supports are simplified as well for easy operation.
