The invention discloses a rotary display screen convenient to dismount. The display screen comprises a bottom box, a connecting opening is formed in the upper side of the bottom box, and a supportingrod which is in sliding connection with the connecting opening is inserted into the connecting opening; a sleeve which is in sliding connection with the supporting rod sleeves the upper end of the supporting rod; the end, away from the supporting rod, of the sleeve is provided with a display screen body fixedly connected with the sleeve; telescopic devices fixedly connected with the bottom box aresymmetrically arranged on the inner side wall of the lower end of the bottom box, and a pressing plate which is fixedly connected with the telescopic devices are arranged at the upper ends of the telescopic devices; a connecting plate which is fixedly connected with the supporting rod is arranged at the lower end of the supporting rod, and the connecting plate is in sliding connection with the connecting opening; limiting blocks which are fixedly connected with the connecting plate are symmetrically arranged at the two ends of the connecting plate. The display screen has the advantages that the supporting rod on the display screen is connected with the bottom box through a clamping connection device, and a limiting rod on a rotating box body is clamped with a limiting block on the supporting rod, so that the display screen is connected with the bottom box, and the display screen can be disassembled conveniently.
