Provided is a water oil machine of an arc telescopic double-layer mesh screen. The arc telescopic double-layer mesh screen utilizes a slide in a pulley-shaped carrier to be mechanically manipulated by self weight of the mesh screen. When the mesh screen is stretched through the slide, an upper layer mesh screen and a lower layer mesh screen are lifted forwards with a pulley in hole-opening state. When the mesh screen is operated to the position close to an oil layer, the upper mesh screen is pulled by a pull strip to slide one screen hole backwards.
