ABSTRACT:
A foldable supporting stand with stoppers in two directions includes a base, a support, a sliding body, a positioning means, a first swinging piece and a second swinging piece. The support is rotatably connected to the base. The sliding body is slidably provided on the support and is further connected to a screen. The first swinging piece and the second swinging piece are swingably connected to the positioning means. The positioning means is connected on the support. When the support is folded on the base, the first swinging piece and the second swinging piece are subjected to their gravitational forces to swing toward the sliding body and thus lock the sliding body. The locked sliding body is restricted from sliding on the support in two directions.
