The invention discloses a propeller quick disassembly and assembly structure and an aircraft provided with the same, and is characterized in that a locking safety device is provided with a first boss, a button is provided with a first groove, and the first boss matches the first groove; an upper inclined face matches the upper matching face of a propeller blade, the upper inclined face can press the upper matching face corresponding to the propeller blade in the blade disassembling and assembling process, a lower inclined face matches the lower matching face of the propeller blade, in the blade assembling and disassembling process, the lower inclined face of the button can carry out linkage according to the lower matching face through vertical movement of the blade, a propeller hub is in a long strip shape, and when the blade is pressed downwards to be attached to the base, the button tightly presses the two ends of the blade and the two ends of the propeller hub through the upper inclined face or the lower inclined face which is correspondingly matched. According to the propeller quick disassembly and assembly structure and the aircraft provided with the same, disassembly and assembly operation is simple, the safety and safety degree is high, abrasion is reduced, cost is saved, and the service life of a product is prolonged.

The invention discloses a high-precision overturning, positioning and side pushing assembly structure. The high-precision overturning, positioning and side pushing assembly structure comprises an overturning mechanism capable of being relatively rotatably mounted on an overturning seat and a side pushing mechanism capable of realizing side pushing, a positioning mechanism for mounting a product is fixedly mounted on one side of an overturning plate of the overturning mechanism, and meanwhile, the side pushing mechanism is relatively slidably mounted on the overturning plate; and after a product is fixedly installed on the overturning plate, the product is overturned to the other side through the overturning mechanism, and then the side pushing mechanism is laterally pushed to be used for being assembled and matched with the product. According to the high-precision overturning, positioning and side pushing assembly structure, one-time high-precision assembling is achieved, the yield and the assembling efficiency are greatly improved, the production cost is remarkably reduced, and the assembly structure is particularly suitable for assembling of intelligent watches.
