The disc 5 is rotatably connected to the outside of a rotating wheel 10 at a specific position inside the probe block 1 through welding. The disc 5 is rotatably connected to the outside of a rotating plate 11. The disc 5 is rotatably connected with a plurality of limiting arc-shaped plates 6, which are plate-shaped structures with arc-shaped surfaces made of metal such as stainless steel and have smooth surfaces. Each two adjacent limiting arc-shaped plates 6 are fixedly connected with an arc-shaped rack 7, which is a structure with teeth distributed along an arc-shaped surface made of metal and closely connected with the limiting arc-shaped plates 6 to provide guidance and power transmission for the movement of the rotating wheel 10. The adjacent side of the two limiting arc-shaped plates 6 is fixedly connected with a double-headed rack plate 8, which is a long strip-shaped component with teeth distributed on both sides made of high-strength alloy steel and capable of moving linearly inside the disc 5 under the drive of the gear 4 while achieving power transmission through the meshing of the teeth with other components. The outside of the double-headed rack plate 8 is meshingly connected to the outside of one of the rotating wheels 10.
