[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1 - 4 , a special tool for operating the plug of the test sampling hole, including a hexagon socket 1. A limit groove 2 is provided inside the hexagon socket 1. A baffle 3 is slidably connected inside the limit groove 2. A magnetic ring 4 is fixedly installed at the bottom end of the baffle 3. A return spring 5 is fixedly installed at the bottom end of the baffle 3. The return spring 5 is fixedly connected to the inner top wall of the hexagon socket 1. A sliding groove 6 is provided above the return spring 5 inside the hexagon socket 1. An ejector rod 7 is slidably connected inside the sliding groove 6. The ejector rod 7 is fixedly connected to the inner top wall of the sliding groove 6 through a tensile spring 8. The ejector rod 7 penetrates through the baffle 3 and extends below the baffle 3. A through groove 9 perpendicular to the sliding groove 6 is provided on the outer surface of the hexagon socket 1. A pull rod 10 is slidably connected inside the through groove 9. The pull rod 10 is connected to the inner ejector rod 7.

[0026] One end of the pull rod 10 is located inside the sliding groove 6 and the other end is located outside the internal hexagonal sleeve 1. The pull rod 10 is threadedly connected to the ejector rod 7. Such a setting can facilitate the assembly of the pull rod 10 and the ejector rod 7.

[0027] Both the pull rod 10 and the ejector rod 7 are hollow, and the pull rod 10 and the ejector rod 7 are connected and penetrate through. Such a setting can enable the pull rod 10 and the ejector rod 7 to exhaust air for the internal hexagonal sleeve 1, avoiding the situation where there is gas inside when connecting the plug and the plug cannot be inserted to the deepest part.

[0028] The length of the limit groove 2 is half of the length of the internal hexagonal sleeve 1. Such a setting can enable the magnetic ring 4 to only drop to half, and the plug part is still located inside the internal hexagonal sleeve 1 to prevent the plug from falling off from the internal hexagonal sleeve 1. The length of the ejector rod 7 is greater than the length of the internal hexagonal sleeve 1. At the same time, when ready, the ejector rod 7 can actively push the plug out of the internal hexagonal sleeve 1 completely and separate from the magnetic ring 4, avoiding the situation where the plug splashes and is not easy to find.

[0029] The internal hexagonal sleeve 1 is divided into multiple sections. It is divided from the top of the limit groove 2 into the upper ejecting section and the lower limiting section. The ejecting section is divided from the top of the sliding groove 6 into the upper handle section. The multiple sections of the internal hexagonal sleeve 1 are welded to each other. Such a setting can facilitate the installation of the baffle 3 and the ejector rod 7 into the internal hexagonal sleeve 1, thus facilitating the assembly.

[0030] On both sides of the connection of the internal hexagonal sleeve 1, load-bearing grooves 11 are provided. Inside the load-bearing grooves 11, welding reinforcing ribs 12 connecting two sections are placed. By providing the load-bearing grooves 11 and setting the welding reinforcing ribs 12 inside the load-bearing grooves 11, the welding strength can be improved.

[0031] The cross-sectional shape of the ejector rod 7 is "T" - shaped, and the shape of the sliding groove 6 is adapted to the shape of the ejector rod 7. Such a setting can limit the ejector rod 7.

[0032] During use, by setting a magnetic ring 4 inside the internal hexagonal sleeve 1, the plug can be adsorbed, and a return spring 5 is set to push the removed plug part out of the internal hexagonal sleeve 1, making it easy to pull out the plug from the internal hexagonal sleeve 1, but still adsorbing the plug through the magnetic ring 4. When it is necessary to reinstall in time after disassembly, only the plug needs to be reset without removing the plug. When it is necessary to continuously remove the plug, the ejector rod 7 can eject the plug out of the internal hexagonal sleeve 1 with a smaller force, thus reducing the range where the plug drops.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
