[0025] It also includes a wire encoder 14 and a connecting wire 15. The inner side of the bottom end of each group of connection frames 6 is respectively connected to the top of a group of wire encoders 14. The input end of the wire encoder 14 is movably connected to the top of the connecting wire 15, and the bottom end of the connecting wire 15 is connected to the corresponding side of the top of the track mechanism 13. When the track mechanism 13 moves, it can drive the connecting wire 15 to move.
