Abstract: A toilet cleaner, including a head and a handle for clamping the head. The handle includes a housing, a manipulation component, and a clamping jaw. A clamping end of the housing is provided with a first clamping head and is hinged to a middle portion of the clamping jaw. The manipulation component is fitted in the housing and includes a handling portion at a grip end of the housing. An outer end of the clamping jaw has a second clamping head corresponding to the first clamping head, and the manipulation component is connected to an inner end of the clamping jaw, so that the first clamping head and the second clamping head are matched with each other. The present invention is more firm and reliable with better compatibility, so that the handle can conveniently and reliably clamp the heads in different thicknesses, or of various brands, forms or specifications.
