This practical new technology involves a golf cart, golf carts, particularly related to the height adjustment device, which includes the base, which connects to the main bar of the golf cart, and slide block which connects to the handle of the golf cart. There are two parallel arc oriented plate formed on each side of the base, and sliding block on both sides of the location near the opening matching with the corresponding slide guide plate. Movement of the sliding block along the base of the curved guide plate adjusts the angle and position between the sliding block and base. Furthermore, the movement can adjust the angle and position of the handle and the main bar and the overall height of the structure. The utility model is simple, suitable for different groups of people, according to needs and to adjust handle height at anytime; low cost and long life.

The utility model involves golf cart technology, particularly related to a folding golf cart, which includes a car chassis, the main bar, push handle, folding bar. The main bar, connector, folding bar, and the car chassis together form a four-bar linkage, the connected action of the four-bar linkage moves other components involved in the action accordingly. During usage, press the button and push the push handle backward/downwards, which drives the main bar and the folding bar forward and closed, and makes the golf cart form into a Z shaped of three-panel folding state. This substantially reduces the size, saves space, and is convenient to store and transport. It is also a simple structure, easy to fold or open, and easy to operate.
