[0025] A lead screw 504 is threadedly connected to the middle of the movable plate 502. One end of the lead screw 504 is rotatably connected to a limit plate 505 via a bearing. Two limit rods 506 are slidably inserted inside the movable plate 502. One end of each limit rod 506 is fixedly connected to the limit plate 505.
