A vending machine includes a rotary dispensing mechanism and a rotary arm mechanism. A control circuit inside the vending machine drives a rotary base of the rotary dispensing mechanism by a stepper motor device, so that an accommodating space of the rotary base is rotated to above an outlet of a fixed frame to discharge a vending item. At this point, a stepper motor device of the rotary arm mechanism is actuated by the control circuit inside the vending machine, and drives a rotary arm to hook out and convey the vending item discharged by the rotary dispensing mechanism. Meanwhile, a transition module at one side of the rotary arm mechanism covers a gap between an adjacent mechanism and a drawing plate, so that the item hooked out can be conveyed stably onto the drawing plate.
