The utility model relates to the technical field of electric fans, and discloses an electric fan with a protection frame assembled and disassembled without tools, which comprises a base, connecting plates are fixedly connected to the left end and the right end of the top side of the base, turntables are rotatably connected to the close sides of the connecting plates at the two ends, and mounting plates are fixedly connected to the close sides of the turntables at the two ends. An electric fan body is mounted on the front side of the mounting plate, a mounting ring is fixedly connected to the rear end of the outer wall of the electric fan body, and the mounting ring is connected with a protection frame through a plurality of mounting assemblies. According to the utility model, when the protection frame needs to be disassembled, the buckles are opened to release the limiting of the upper and lower fixing rings, and then the rotating shaft is rotated to separate the upper and lower fixing rings and disassemble the upper and lower fixing rings, so that the limiting of the mounting rod is released. And then the other rotating shaft is rotated to drive the mounting rod to rotate, so that the fixing block is separated from the fixing groove, and the protection frame can be disassembled. The whole process does not need tools, time is saved, and the maintenance difficulty is lowered.
