The elevator door comprises a door frame, a door leaf arranged on the door frame in a rotatable opening and closing mode and a power device used for driving the door leaf to rotate, and the power device comprises a driver, a transmission mechanism connected with the driver, an executing mechanism connected with the door leaf and a clutch piece connecting the transmission mechanism and the executing mechanism. The door is characterized in that a rotatable handle is arranged on the inner side of the door frame, the handle is connected with the clutch piece through a linkage structure, and when the handle rotates, the linkage structure drives the clutch piece to move so that the transmission mechanism can be separated from the executing mechanism. When a user is trapped in the elevator car due to power failure, the user can unlock the executing mechanism by pulling the handle, a special key does not need to be carried, and safety and reliability are achieved.
