Continuing to use it may also blow dirt toward the user. The fan needs to be disassembled, cleaned, replaced and repaired. The blades of some fans can be removed separately, but the installation and removal process is troublesome.

[0003] For example, the Chinese patent document with publication number CN107461366A discloses a fan blade for a floor fan, including a front mesh cover, a fixed chassis, a motor, a rear mesh cover, a fan blade, and a fan blade cable nut, counterweights are installed on both sides of the bottom of the fixed chassis, and a base column is vertically installed at the middle position of the top of the fixed chassis, a fastening clamp is installed at the top of the base column, and a telescopic support rod is vertically installed inside the base column through the fastening clamp. By installing a fan blade fixing seat, a fan blade cable nut, a threaded screw, a fixing nut and a second fixing screw hole, the fixing nut is twisted to loosen the threaded screw during use, and the fan blade fixing seat is rotated to adjust the angle and then the fixing nut is tightened, so that the fan blade can adjust the angle at any time, and the device is enhanced in stability by installing a counterweight.

[0004] In the technical solution of the above patent document, the front and rear mesh covers are separated by screwing the nut in the first fixing screw hole on the fixing plate, and then the slider is slid to remove the fan blades for cleaning. However, the blades need to be disassembled one by one, and the positioning block and the blade rope nut need to be disassembled to remove the rear mesh cover. The disassembly takes a long time, which affects the cleaning efficiency. Utility Model Content
