<p>A thee-sectional golf cart structure includes a stretchable hand pull-bar (1), two struts (2) for wheels (21), a "U" shaped lower stand (3) and two links (4). The hand pull-bar (1) includes an inner tube (12) and an external sleeve (13). Each of the two struts (2) is provided at one end thereof with a wheel (21) and the two links (4) have their ends connected to the struts (2) and the external sleeve (13) respectively. Thereby, when the hand pull-bar (1) is pulled up, it moves therewith the two links (4) to stretch out the two struts (2) and the wheels (21), while down pressing of the hand pull-bar (1) will collapse the two struts (2) and the wheels (21) to be received in the two lateral sides of the "U" shaped lower stand (3) and, by stretching and retracting of the three members including the inner tube (12), the external sleeve (13) and the "U" shaped lower stand (3), the thee-sectional golf cart structure is formed.</p> |
