The other ends of the links are connected with sliding rails. A slider is connected to the sliding rails. A T-shaped bracket is arranged between the two links in the automobile door, and the free ends of a crossbar of the T-shaped bracket are hinged to the corresponding sliding blocks. A longitudinal rod of the T-shaped bracket is a rack which is connected with a first gear. A second gear is arranged on a main shaft of the first gear, and the second gear is connected with a manual gear. The manual gear comprises a connecting plate hingedto the automobile door. One end of the connecting plate is provided with a sector gear in transmission connection with the second gear. The other end of the connecting plate extends out of the innerwall of the automobile door to be connected with a hand shifting part. Since the rack cooperates with the two links, the horizontal movement of the rack controls the two snap blocks to open or close for opening or closing the automobile door respectively.
