As shown in fig. 1and 2, the quick release structure provided in this embodiment includes a first member, a second member, and a lock structure. In the present embodiment, a first member is taken as a propeller 1, and a second member is taken as a shield 2. Of course, when the first member and the second member are other members, the quick release structure is also within the scope of the present invention.
The screw propeller 1 is provided with a bump 151, the protecting cover 2 is provided with a slot 231, and the bump 151 is inserted into or separated from the slot 231 along a first direction (L direction shown by an arrow in fig. 2), so that the screw propeller 1 and the protecting cover 2 are installed or detached along the first direction (L direction shown by the arrow in fig. 2). The protrusion 151 is inserted into the slot 231 to limit the relative movement of the propeller 1 and the protective cover 2 in the direction perpendicular to the first direction, that is, the slot 231 and the insert block can limit the relative movement of the propeller 1 and the protective cover 2 in the up-down direction and the front-back direction (the direction perpendicular to the paper surface).
