Abstract
A pushcart handle height adjusting mechanism comprises an upper rod (13), a right lower rod (15), a left lower rod, locking holes (20, 21, 22), a right locking pin (24), a left locking pin, a right locking spring (28), a left locking pin, a right slide rod (29), a left slide rod, a connecting rod (36), and adjusting springs (42). When the connecting rod (36) is pulled up to upwardly slide the right slide rod (29) and the left slide rod, the right locking pin (24) and the left locking pin are pushed by the right slide rod (29) and the left slide rod and thereby retracted from the inner wall surfaces of the right lower rod (15) and left lower rod. In this state, if the upper rod (13) is operated for upward or downward movement, the right locking pin (24) and the left locking pin are disengaged from the locking holes (22) to move onto the outer wall surfaces of the right lower rod ( 15) and left lower rod.
