[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0015] In related technical fields, when equipment needs to be dismantled for leveling or repairing malfunctions, a jack and a hammer are used to knock off the nuts on the Green Column 5. Taking the removal of four nuts as an example, the removal time is about 1 to 1.5 hours, which is a long repair time and requires a lot of manpower.

[0016] In view of the above, this application provides a nut that aims to overcome at least one of the above-mentioned technical problems.

[0017] Please see Figure 1 The nut comprises a first body 1 and a second body 2. Please refer to [link / reference]. Figure 2 The first body 1 has a first mating surface 11 and a first through groove 12. The first through groove 12 penetrates the first mating surface 11 and extends through the first body 1 along a first direction X. The inner wall of the first through groove 12 is provided with a first thread 13. Please refer to [link to relevant documentation]. Figure 3 The second body 2 has a second mating surface 21 and a second through groove 22. The second through groove 22 penetrates the second mating surface 21 and extends through the second body 2 along a first direction X. The inner sidewall of the second through groove 22 is provided with a second thread 23. The first mating surface 11 and the second mating surface 21 are detachably mated and connected so that the first through groove 12 and the second through groove 22 communicate to form an adjustment cavity 31 for accommodating a portion of the Green Post 5. The first thread 13 and the second thread 23 cooperate to form an adjustment thread for engaging with the external thread on the Green Post 5.

[0018] The nuts in this embodiment are composed of a first body 1 and a second body 2. When disassembling the Green Post 5, the first body 1 and the second body 2 can be separated, and the first body 1 and the second body 2 can be removed from the Green Post 5 without having to unscrew the nuts by hammering. The actual removal of the four nuts takes about 15 to 20 minutes, which shortens the maintenance time and saves labor costs.

[0019] Please see Figure 4In some embodiments, a connector 4 is also included, which connects the first body 1 and the second body 2 so that the first mating surface 11 and the second mating surface 21 are mated and connected. The connector 4 may be a ring structure sleeved on the outer periphery of the first body 1 and the second body 2. By abutting against the first body 1 and the second body 2, and in combination with the engagement of the adjusting thread and the external thread on the Green Post 5, the connector prevents the first body 1 and the second body 2 from moving up and down or outward, and locks the positions of the first body 1 and the second body 2 in a suitable position on the Green Post 5.

[0020] For technical solutions that do not include a connecting piece 4, corresponding locking structures can be provided on the first body 1 and the second body 2. For example, an elastic locking tongue can be provided on the first body 1 and a corresponding locking buckle can be provided on the second body 2. The locking tongue can be engaged with the locking buckle during mating connection. Combined with the cooperation of the adjusting thread and the external thread on the Green Post 5, the first body 1 and the second body 2 can be prevented from moving up and down or outward, and the positions of the first body 1 and the second body 2 can be locked in the appropriate position on the Green Post 5.

[0021] For a technical solution that does not include a connector 4, a groove can be pre-set on the equipment. After the first body 1 and the second body 2 are matched, they move with the Green Post 5 so that the first body 1 and the second body 2 are placed into the groove. Combined with the engagement of the adjusting thread and the external thread on the Green Post 5, the first body 1 and the second body 2 are prevented from moving up and down or outward, and the positions of the first body 1 and the second body 2 are locked in the appropriate position on the Green Post 5.
