Zusammenfassung:	A handle folding mechanism, a three-fold handle (48) employing the folding mechanism, and a trolley having the same. The folding mechanism includes an intermediate component (1) and a pair of connecting components (2). The intermediate component (1) includes a tubular casing (11), a press block (12), and an unlocking piece (13). A rear part of the press block (12) passes through a front surface of the casing (11) to extend into the casing (11), and is movable back and forth. The connecting component (2) includes a tubular housing (21) and an engaging piece (22). The engaging piece (22) is slidably mounted in the housing (21). In a locked state, a front end of the engaging piece (22) penetrates into the casing (11). The unlocking piece (13) has a fixing part, and the fixing part is disposed with a free end extending between a rear end of the press block (12) and the front end of the engaging piece (22).
