The invention relates to a bottled and canned drink discharge anti-tilt mechanism for a vending machine. The mechanism comprises a storage drawer which can accommodate commodities, wherein the storage drawer is provided with a front end part and a rear end part; a closed display wall is arranged in front of the storage drawer, so a user can observe the commodities in the storage drawer through the display wall; a space is formed at the front ends of the display wall and the storage drawer, so the commodity selected by the user can fall down from the space; a discharge anti-tilt mechanism is arranged on the front end part of the storage drawer and comprises a stop lever which is arranged on the front end part of the storage drawer; the stop lever stands on the front end part of the storagedrawer; the height of the stop lever is more than that of the center of gravity of the commodities placed on the storage drawer; and the stop lever can prevent the head of the commodity from tilting when the commodity falls down from the front end part of the storage drawer. After the bottled and canned drink discharge anti-tilt mechanism is adopted, a drink bottle falls down in a placement mode during the falling so as to avoid tilting and guarantee normal discharge.
