[0004] In the description of Chinese utility model patent application publication CN208311080U, a detachable fan base is disclosed, which includes a support base. The top of the support base is movably connected with a support arm. The top of the support arm is fixedly connected with a fan holder. The inner cavity of the fan holder is provided with fan blades. The inner cavity of the fan blades is provided with protection rods. The number of protection rods is not less than ten. The front surface of the fan holder is provided with a protective plate. The bottom of the support arm is fixedly connected with an insertion block. The bottom of the insertion block penetrates into the bottom of the inner cavity of the support base. The utility model can conveniently detach the base and the fan body by the cooperation of the insertion block, reinforcing plate, first movable plate, second movable plate, horizontal plate, through hole, clamping block, clamping groove, spring and extrusion rod. It is simple to operate and convenient to use, so it is convenient to carry and transport the fan. Moreover, the connection between the base and the fan body will not be broken during carrying, ensuring the normal use of the fan.
