Since opposite threads are provided at both ends of the first lead screw 15, and the first lead screw 15 and the sliding seat 16 are movably connected by threads, the sliding seats 16 on both sides will move inward synchronously. When the position of the sliding seat 16 corresponds to the width direction of the medical door, turn off the first motor 18, and then turn on the second motor 27. The second motor 27 drives the transmission belt 29 to move through the transmission wheel 28 connected to the output end, and then drives another transmission wheel 28 to rotate, and then the transmission wheel 28 here drives the gear 26 set on one side to rotate, and then the gear 26 here drives the other gear 26 meshing with it to rotate, and then Another gear 26 will drive the second lead screw 22 connected thereto to rotate. Since the second lead screw 22 and the guide rod 20 are movably connected by threads, the guide rod 20 will slide along the second lead screw 22, and at the same time, the guide rod 20 will slide in the guide groove 21. Due to the special structural design of the guide groove 21 and the movable frame 23, when the guide rod 20 slides in the guide groove 21, the movable frame 23 will slowly rise, and then the side wall of the movable frame 23 will clamp the medical door in the width direction of the medical door, and then the second motor 27 will be turned off, and then the bolt 24 will be rotated. Since the bolt 24 and the pressure plate 19 are movably connected by threads, and the limit plate 25 limits the pressure plate 19, the pressure plate 19 will descend along the bolt 24. When the pressure plate 19 presses the medical door in the thickness direction and positions it, the bolt 24 can be stopped.
