The inner wall of the cavity 61 is rotatably connected to the gear 2 64, the gear 2 64 is meshed with the gear 1 62, and the gear 2 64 is meshed with the rack 63. The surface of the fixed ring 60 is fixed with a bottom plate 602, and the surface of the bottom plate 602 is fixed with a motor 65. There are four groups of racks 63, and the four groups of racks 63 are all arranged in a circular array with the center of the fixed ring 60 as the axis. The surface of one of the four groups of racks 63 is fixed with a fixed plate 66. The outer surface of the motor 65 is rotatably connected to a threaded rod 67, and the threaded rod 67 is away from the motor. One end of the motor 65 passes through the fixed plate 66, and the threaded rod 67 is threadedly connected to the fixed plate 66. A groove 68 is provided on the surface of the threaded rod 67, and a stabilizing plate 69 is fixed to the inner wall of the groove 68. The output shaft of the motor 65 extends into the groove 68. The output shaft surface of the motor 65 is hinged with a movable plate 600. The surface of the movable plate 600 is fixed with a torsion spring 601. One end of the torsion spring 601 is fixed to the output shaft surface of the motor 65. There are four groups of gears 2 64, and the four groups of gears 2 64 are all arranged in a circular array with the center of the fixed ring 60 as the axis center. The end of the rack 63 close to the jack 4 is set to an arc shape. Wheel 1 62 is set below the rack 63. When the motor 65 is turned on and rotated forward, the movable plate 600 rotates. When the surface of the movable plate 600 conflicts with the surface of the stabilizing plate 69, the threaded rod 67 rotates forward, and the fixed plate 66 drives the rack 63 to move closer to the jack 4.
