Mounting plates 102 are fixedly provided on both sides of the fixed plate 101. Rollers 106 are rotatably arranged at the upper end positions of the inner walls on both sides of the fixed plate 101;

[0025] Specifically, the lifting mechanism 1 is conducive to driving the middle passenger ladder 201 to move up and down. The fixed plate 101 is conducive to the installation of the wire reel 104. The wire reel 104 is conducive to driving the winding and unwinding of the steel wire rope 105 after rotation. The steel wire rope 105 is conducive to being used in cooperation with the mounting buckle 107 and is conducive to connecting and installing with the passenger ladder 201. The sliding groove 103 is conducive to the up and down sliding of the passenger ladder 201 in the middle. The first servo motor 110 is conducive to driving the threaded rod 111 to rotate. The threaded rod 111 is conducive to driving the threaded box 112 on its outer surface to move up and down. The middle parts of the two threaded boxes 112 are fixedly installed with the passenger ladder 201, which is conducive to driving the passenger ladder 201 to lift. The installation groove 108 is conducive to the fixed installation of the telescopic rod 109.
