This utility model relates to the technical field of biscuit processing equipment, specifically a hard-limit positioning pin mechanism. It includes a frame, a drive shaft located at the center of the top surface of the frame, a turntable mounted on the top of the drive shaft, and positioning components mounted on the outer circumference of the drive shaft. Multiple positioning seats are mounted on the top surface of the frame, circumferentially along the drive shaft. Rotation of the drive shaft causes the positioning components to engage with positioning seats at different positions.
