The invention provides an elevator synchronous door vane device provided with a holding assembly. The elevator synchronous door vane device comprises a door vane bottom plate, a traction device, a four-connecting-rod mechanism and the holding assembly, wherein the four-connecting-rod mechanism consists of a driving swing arm, a driven swing arm, a first door vane and a second door vane; one end of the driving swing arm is a limiting end; the driving swing arm is connected with the door vane bottom plate through a first center shaft; the driven swing arm is connected with the door vane bottom plate through a second center shaft; the holding assembly comprises a first movable rod, a second movable rod, and a connecting shaft for connecting the first movable rod with the second movable rod; the connecting shaft is provided with an overhanging end; a guide device is arranged at the overhanging end; the holding assembly further comprises a guide plate matched with the guide device. According to the elevator synchronous door vane device provided by the invention, an elevator car door and a hall door are opened and closed simultaneously, so that shaking of an elevator door is prevented, and the car door is tightly closed when an elevator is in a non-door area in case of a failure; when the elevator is in a door area, the hall door can be driven to be opened by the car door, so that the door vane device having a function of preventing forced door opening is simplified.
