The invention discloses a labor-saving inclined lifting mechanism and an inclined lifting projection scene board device. The labor-saving inclined lifting mechanism comprises a guide rail, a rail fixing frame, a traction rope, a first steering wheel, a second steering wheel, a supporting frame and a main lifting frame; the guide rail is fixedly connected with the rail fixing frame; a guide wheel and a traction wheel are fixedly arranged at the front end of the main lifting frame; the supporting frame is provided with rollers; the first steering wheel and the second steering wheel are respectively fixed; the traction rope forms a traction path with a certain lifting stroke. The inclined lifting projection scene board device comprises an image scene board, the labor-saving inclined lifting mechanism and a fixing frame; the image scene board is hinged to the main lifting frame and the fixing frame; and the supporting frame is fixed with the image scene board. The labor-saving inclined lifting mechanism and the inclined lifting projection scene board device have the beneficial effects that energy can be saved, and efficiency can be improved; in addition, in the descending process, buffering force is achieved, the service life of equipment can be prolonged, and the use safety of the equipment is improved.
