A hollow through hole is provided inside the limit shell 1, so that the limit shell 1 can be sleeved on the outside of a solid object to be identified. An annular groove 9 is provided inside the limit shell 1, and a connecting groove 10 and a rotating groove 11 are provided inside one side of the limit shell 1. The rotating groove 11 is located at one end of the connecting groove 10, and the connecting groove 10 is connected to the annular groove 9, so that when an object moves inside the connecting groove 10, it can also drive the object inside the annular groove 9 to move;

[0030] The bottom end of the annular groove 9 is evenly distributed with rolling balls 6, so that the bottom of the rolling balls 6 can contact the bottom end of the annular groove 9, and then the rolling balls 6 can rotate and move at the bottom end of the annular groove 9. The inside of the annular groove 9 and the top of the rolling balls 6 are slidably connected with an adjusting ring 5, and the adjusting ring 5 is in the shape of a rotating body, so the adjusting ring 5 can both slide and rotate inside the annular groove 9;

[0031] The inner thread of one end of the limiting shell 1 is connected to a threaded rod 2, and one end of the threaded rod 2 is located inside the rotating groove 11, and the other end of the threaded rod 2 is located inside the connecting groove 10, so that the threaded rod 2 can be rotated to adjust the length of the threaded rod 2 inside the connecting groove 10 and the rotating groove 11. An assembly groove is opened inside one end of the threaded rod 2, so that an external tool can be connected to the assembly groove to drive the threaded rod 2 to rotate, and the assembly groove is located on the inner side of the rotating groove 11, which can be easily connected to the assembly groove.

[0032] The other end of the threaded rod 2 is rotatably connected to the connecting block 3 located inside the connecting groove 10, so that the connecting block 3 can be driven to move by the rotation of the threaded rod 2. A connecting bolt 8 is provided inside the connecting block 3, and the connecting bolt 8 is threadedly connected to the adjusting ring 5. A positioning threaded hole 18 is provided inside the adjusting ring 5 at a position corresponding to the connecting bolt 8. The connecting bolt 8 and the adjusting ring 5 are threadedly connected through the positioning threaded hole 18, so that the adjusting ring 5 can be driven to rotate on the inner side of the annular groove 9 by the movement of the connecting block 3. A plurality of first sliding surfaces are evenly distributed on the top of the adjusting ring 5, so that the plurality of sliding surfaces can form head-to-tail contact;

[0033] In this embodiment, the included angle between the center of the threaded rod 2 and the limiting housing 1 is inclined, so that the threaded rod 2 can drive the adjusting ring 5 through the connecting block 3 when rotating, allowing the adjusting ring 5 to rotate inside the annular groove 9.

[0034] In this embodiment, the number of the first sliding surfaces is eight. In other embodiments, the number of the first sliding surfaces can be determined according to needs and the diameter of the adjustment ring 5 .

[0035] The first sliding surface is composed of a third connecting surface 23 and a fourth connecting surface 24. The fourth connecting surface 24 is an inclined surface. One end of the fourth connecting surface 24 is connected to the third connecting surface 23. The third connecting surface 23 is a plane. Therefore, the third connecting surface 23 and the fourth connecting surface 24 can be driven to rotate by the rotation of the adjusting ring 5. A second limiting groove 19 is formed inside the top end of the fourth connecting surface 24. A rotating bead 20 is slidably connected inside the second limiting groove 19.

[0036] Inside the annular groove 9 and at the top of the adjusting ring 5, there is a lifting switch 4 slidably connected. The lifting switch 4 is in the shape of a rotating body, so that the lifting switch 4 can not only slide but also rotate inside the annular groove 9. The bottom of the annular groove 9 is evenly distributed with a second sliding surface that cooperates with the first sliding surface, so that multiple second sliding surfaces can form head-to-tail contact.

[0037] In this embodiment, two first assembly threaded holes 21 are provided on the top of the adjustment ring 5, so that the adjustment ring 5 can be moved and assembled or disengaged from the annular groove 9 by connecting an external tool to the first assembly threaded holes 21;

[0038] The second sliding surface is composed of a first connecting surface 16 and a second connecting surface 17. The first connecting surface 16 is a plane, one end of which is connected to the second connecting surface 17. The second connecting surface 17 is an inclined surface, which can be driven by the rotation of the connecting block 3 to drive the fourth connecting surface 24 to rotate. The rotation of the fourth connecting surface 24 drives the second connecting surface 17 in contact with it to move. A first limiting groove 15 is opened inside the bottom end of the second connecting surface 17, and the first limiting groove 15 is slidably connected to the rotating ball 20.

[0039] The position of the lifting switch 4 corresponding to the first connecting surface 16 is equipped with a positioning assembly, which includes a return spring 13 and a positioning bolt 14. A rectangular groove 12 is provided inside and at the top of the first connecting surface 16. A positioning thread groove is provided inside and at the position corresponding to the first connecting surface 16 of the lifting switch 4. The return spring 13 is slidably connected with the positioning thread groove, so that the return spring 13 enters the interior of the rectangular groove 12 through the sliding connection with the positioning thread groove, thereby enabling the return spring 13 to be assembled on the inner side of the rectangular groove 12 through the positioning thread groove. The internal thread of the positioning thread groove is connected with the positioning bolt 14, and the top of the positioning bolt 14 is located inside the bottom end of the return spring 13, thereby enabling the return spring 13 to be positioned. A limiting bolt 7 is provided inside the limiting shell 1 and at a position corresponding to the return spring 13, and the limiting bolt 7 is slidably connected with the rectangular groove 12, so that one end of the limiting bolt 7 can pass through the outside of the limiting shell 1 and enter the interior of the return spring 13 and then be threadedly connected with the inner side of the limiting shell 1, thereby limiting the lifting switch 4 to only be able to slide after the internal assembly of the annular groove 9 is completed;

[0040] In this embodiment, two second assembly threaded holes 22 are provided on the top of the lifting switch 4, so that the lifting switch 4 can be moved and assembled or separated from the annular groove 9 by connecting an external tool to the second assembly threaded holes 22;

[0041] When the height of the lifting switch 4 needs to be adjusted, the threaded rod 2 is rotated by the cooperation of the external tool and the assembly groove. The rotation of the threaded rod 2 allows it to move its position inside the limit shell 1 and can adjust its length inside the connecting groove 10. The rotation of the threaded rod 2 drives the connecting block 3 of the rotation connection to move, and according to the connection between the connecting block 3 and the adjusting ring 5 through the connecting bolt 8, the connecting block 3 is allowed to rotate without following the threaded rod 2. At the same time, the connecting block 3 can move to drive the connecting groove 10 to rotate inside the annular groove 9. The rotation of the adjusting ring 5 allows the adjusting ring 5 to slide on the top of the rolling ball 6. At the same time, the rotation of the adjusting ring 5 drives The first sliding surface rotates, and is slidably connected to the rectangular groove 12 by the limiting bolt 7, so that the rotation of the first sliding surface drives the second sliding surface matched therewith to slide, and then the fourth connecting surface 24 can drive the second connecting surface 17 to slide. By inclining the fourth connecting surface 24 and the second connecting surface 17, the lifting switch 4 can be lifted and lowered when the adjusting ring 5 rotates. The lifting and lowering of the adjusting ring 5 drives the rectangular groove 12 and the positioning bolt 14 to rise and fall, so that the adjusting ring 5 can squeeze the return spring 13 through the limiting bolt 7 when rising, so that the bottom of the lifting switch 4 can always be in contact with the top of the adjusting ring 5 when the adjusting ring 5 descends;

[0042] During assembly, first install the threaded rod 2 through the threaded connection with the limit shell 1. At this time, the connecting block 3 is already on the outside of one end of the threaded rod 2. Then, the rolling ball 6 is installed at the bottom end of the inner side of the annular groove 9. Then, the adjusting ring 5 is connected to the first assembly threaded hole 21 through an external tool to drive the first assembly threaded hole 21 to smoothly enter the annular groove 9 of the sliding connection, while keeping the rotating ball 20 on the inner side of the second limit groove 19. Then, the connecting block 3 is connected to the adjusting ring 5 through the cooperation of the connecting bolt 8 and the positioning threaded hole 18. Then, the lifting changer 4 is connected to the second assembly threaded hole 22 through an external tool to drive the second assembly threaded hole 22 to smoothly enter the annular groove 9 of the sliding connection. Then, slightly rotate the lifting changer 4 to adjust the position of the lifting changer 4 at the top of the adjusting ring 5. Then, the limiting bolt 7 is entered into the interior of the rectangular groove 12 through the sliding connection with the outside of the limit shell 1, and passes through the inner side of the reset spring 13 and is connected to the inner side of the limit shell 1, thereby limiting the lifting changer 4 to be able to rise and fall only inside the annular groove 9, and at the same time, the reset spring 13 can be squeezed.
