[0005] To solve the above technical problems, the utility model provides the following technical scheme: a special-shaped nut with wire drawing groove, comprising a nut main body, a fan-shaped arc groove is formed on the surface of the nut main body, a special-shaped part is arranged at the top of the nut main body, a first crescent surface is arranged at the top of the special-shaped part, and a second crescent surface is arranged at the position away from the first crescent surface at the top of the special-shaped part.
[0006] Preferably, a first U-shaped hole is formed at the connection between the fan-shaped arc groove and the first crescent surface, a second U-shaped hole is formed at the connection between the fan-shaped arc groove and the second crescent surface, and the size of the first U-shaped hole is the same as that of the second U-shaped hole.
[0007] Preferably, the shape of the nut main body is a regular hexagon, and a threaded groove is formed at the center of the nut main body.
[0008] Preferably, the first crescent surface is located in the recessed part at the top of the special-shaped part, and the second crescent surface is located in the recessed part at the top of the special-shaped part.
[0009] Preferably, the nut main body and the special-shaped part are metal components.
[0010] The utility model has the following technical effects and advantages:
[0011] In the scheme, after the special-shaped nut with a wire drawing groove is threadedly connected with the bolt, the operator can connect the matched buckle with the special-shaped part on the top of the nut body, so that the buckle seals the connection position of the nut and the bolt exposed in the air, thereby preventing oxygen and water vapor in the air from penetrating through the connection position, and the effect of prolonging the service life of the bolt and the nut is achieved.

[0016] In order to make the technical problem, technical scheme and advantages to be solved by the utility model more clear, the following will be described in detail in combination with the drawings and specific embodiments.
[0017] As shown in the accompanying Figure 1 to the accompanying Figure 3 Embodiments of the utility model provide a special-shaped nut with a wire drawing groove, which comprises a nut body 1, the surface of the nut body 1 is provided with a fan-shaped arc groove 2, the top of the nut body 1 is provided with a special-shaped part 3, the top of the special-shaped part 3 is provided with a first crescent surface 4, and the position, away from the first crescent surface 4, of the top of the special-shaped part 3 is provided with a second crescent surface 6.
[0018] Among them, the connecting place of the fan-shaped arc groove 2 and the first crescent surface 4 is provided with a first U-shaped hole 5, the connecting place of the fan-shaped arc groove 2 and the second crescent surface 6 is provided with a second U-shaped hole 7, and the size of the first U-shaped hole 5 is same with the size of the second U-shaped hole 7.
[0019] Among them, the shape of the nut body 1 is regular hexagon, and a threaded groove is arranged at the center of the nut body 1.
[0020] Specifically, the shape of the nut body 1 is regular hexagon, so that the nut body 1 has edges and corners in the installation process, and the operator can conveniently use pliers to connect the special-shaped nut and the bolt together.
[0021] Among them, the first crescent surface 4 is located in the recessed part on the top of the special-shaped part 3, and the second crescent surface 6 is located in the recessed part on the top of the special-shaped part 3.
