[0002] Propellers are a crucial component of drones. Similar drones currently on the market require the use of tools like screwdrivers for disassembly and assembly. To facilitate drone portability and prevent damage to the wings, propellers require frequent and timely disassembly and assembly. Furthermore, existing propeller mounts are typically secured to the propeller blades with bolts. During flight, high-speed propeller blades can become detached from the mounts, causing the drone to lose power and fall, potentially causing damage.

[0003] The UAV propeller seat quick-release structure disclosed in Chinese patent CN202220420527.X includes a fixing screw, which is fixedly mounted on the connecting frame along the axial direction of the connecting frame; the UAV propeller seat is provided with a mounting portion for mounting a propeller at one end and a connecting disk at the other end, the connecting disk is provided with an arc-shaped fixing groove, the fixing screw can slide in the fixing groove, the fixing groove includes a clamping portion and a disassembly portion, the size of the disassembly portion is larger than the size of the head of the fixing screw, and is used to allow the fixing screw to pass in or out, the clamping portion is provided with a countersunk hole, when the fixing screw is located in the clamping portion, the head of the fixing screw is limited in the countersunk hole; a spring piece is elastically supported between the connecting frame and the connecting disk, when the fixing screw is located in the clamping portion, the elastic force of the spring piece puts the connecting disk in a tensioned state, and when the fixing screw is located in the disassembly portion, the elastic force of the spring piece is used to keep the connecting disk away from the connecting frame. This utility model can be quickly disassembled and assembled through the cooperation of the fixing screws and the clamping part and the disassembly part in the fixing groove, and can quickly disassemble and assemble the drone propeller seat. However, this utility model cannot provide anti-rotation protection for the drone blades set on its drone propeller seat.
