Quick-release mechanism for fan, fixing assembly for fan, and fan assembly

A quick-release mechanism for fan, adapted to be mounted on a fan, wherein the fan has two lateral surfaces, a top surface connected to the two lateral surfaces, and two end surfaces connected to the two lateral surfaces, wherein the quick-release mechanism for fan comprises:

• a first lateral cover and a second lateral cover adapted to be mounted on the two lateral surfaces, respectively, wherein the first lateral cover has a slot hole in communication with an outer surface and an inner surface of the first lateral cover, and the inner surface faces the corresponding lateral surface;
• a latch member extending from an edge of the slot hole, wherein the latch member has an engaging block and an actuation portion;
• the engaging block normally protrudes from the outer surface, the actuation portion is connected to the engaging block, and an actuation gap is between the actuation portion and the inner surface of the first lateral cover;
• a handle having a first pivot end and a second pivot end, wherein the first pivot end and the second pivot end are pivotally connected to the first lateral cover and the second lateral cover, respectively, so that the handle is rotatable with respect to the first lateral cover and the second lateral cover and is movable between a first position and a second position;
• at the first position, the handle is side-by-side arranged with the top surface;
• at the second position, an angle is between the handle and the top surface;
• and
• a pushing member disposed at the first pivot end and corresponding to the actuation portion of the latch member, wherein when the handle is at the first position, the actuation portion moves toward the first lateral cover;
• when the handle is at the second position, the pushing member pushes the actuation portion to move toward a direction away from the inner surface.
