The invention discloses a two-way sliding anti-drawing spherical support which comprises an upper support plate, a spherical crown liner plate, a middle steel liner plate and a lower support plate. Aforward L-shaped cantilever is arranged on the lower surface of the upper support plate in the bridge direction. A reverse L-shaped cantilever is arranged on the upper surface of the lower support plate in the transverse bridge direction. Flanges are arranged at the upper end and the lower end of the middle steel liner plate. The flanges at the two ends are arranged in grooves of the forward L-shaped cantilever and the reverse L-shaped cantilever and are in plane sliding connection with the grooves. An arc-shaped groove is formed in the middle portion of the upper end of the middle steel linerplate. The upper surface of the spherical crown liner plate and the lower surface of the upper support plate are in plane sliding connection. A bottom cambered surface is arranged in the arc-shaped groove of the middle steel
