The invention discloses a multifunctional type projector structure. The structure comprises an engine base. A first rotation groove whose opening faces towards the right is fixedly arranged in the engine base. A first loading chamber is connected and arranged into the right end wall of the first rotation groove. Several groups of first chutes whose openings face downwardly are connected and arranged into the upper end wall of the first loading chamber. A second rotation groove whose opening faces upwardly is connected and arranged into the lower end wall of the first loading chamber. The rightside of the second rotation groove is provided with an empty groove located in the engine base. A first rotation column is rotatably arranged between the upper and lower end walls of the first rotation groove. The external surface of the first rotation column is fixedly provided with a door body. The door body is inserted into the first loading chamber. Several groups of third rotation grooves whose openings face upwardly are fixedly arranged in the door body. The equipment structure is simple, usage is convenient, equipment adopts a double-locking mode, a high-efficiency storage management function during a usage process is realized, and the reliability of a projector is effectively increased.
