A first threaded rod 7 is rotatably connected in the first groove 111. One end is rotatably connected to the first slide groove 111 via a bearing seat (not shown in the figure), and the other end passes through and is rotatably connected (via the bearing seat) to the first crossbeam 11 and is fixedly connected to the output end of the first servo motor 8 mounted on the first crossbeam 11.
