[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] An embodiment of the present utility model provides a special-shaped nut wrench 100 .

[0026] See also Figure 1 and Figure 2 In one embodiment of the present invention, the special-shaped nut wrench 100 includes a handle portion 120 and a working portion 130 connected to the handle portion 120 , and the working portion 130 is used to tighten the special-shaped nut 200;

[0027] A limiting portion 210 is provided on the side of the special-shaped nut 200, and a matching portion 131 is provided on the side of the working portion 130 (the specification explains that it is from the vertical direction of the rotation direction). The limiting portion 210 cooperates with the matching portion 131; when the handle portion 120 is rotated, the working portion 130 can be driven to rotate in the screwing direction of the special-shaped nut 200.

[0028] It can be understood that the technical solution of the present invention is to set a handle part 120 and a working part 130, specifically to set a matching part 131 on the side of the working part 130, and to configure a limiting part 210 on the side of the special-shaped nut 200. The limiting part 210 cooperates with the matching part 131 to drive the working part 130 to rotate in the direction of the special-shaped nut 200 when the handle part 120 is rotated, and then drive the special-shaped nut 200 to be tightened relative to the connecting structure of the special-shaped nut 200, thereby solving the problem that the existing wrench cannot tighten the special-shaped wrench.

[0029] It should also be noted that the lateral direction of the special-shaped nut 200 is a direction perpendicular to the screwing direction of the special-shaped nut 200 ; the lateral direction of the working portion 130 is also a direction perpendicular to the screwing direction of the special-shaped nut 200 .

[0030] It should also be noted that the limiting portion 210 described in the embodiment of the present utility model can be a limiting protrusion integrally formed with the special-shaped nut 200, or a limiting groove.

[0031] When the limiting portion 210 is a limiting groove, the matching portion 131 is a protruding structure; when the limiting portion 210 is a limiting protrusion, the matching portion 131 is a limiting groove.

[0032] It is understandable that in order to prevent the protruding structure from scratching or damaging the special-shaped nut 200 and to improve the assembly efficiency of the limiting portion 210 and the matching portion 131, the structure of the matching portion 131 is preferably a limiting groove.

[0033] Please continue reading Figure 1 and Figure 2 In a specific embodiment of the present invention, the limiting portion 210 is a limiting protrusion, and the matching portion 131 includes a groove having at least two continuous openings.

[0034] It is understood that the at least two continuously open grooves may be formed by having an opening on the top wall and a notch on at least one side wall. It is also understood that the provision of the notch can improve the assembly efficiency between the groove and the limiting protrusion, and the provision of the notch can also increase the applicability of the special-shaped nut wrench 100 (applicable to limiting protrusions of different shapes).

[0035] Furthermore, in a specific embodiment of the present invention, the working portion 130 is formed with an escape opening 130 a , and the escape opening 130 a is used to avoid the connection structure of the special-shaped nut 200 .

[0036] It is understandable that the nut is usually connected to a connecting structure such as a bolt, a pipe, or a wire pipe. Therefore, an avoidance opening 130a is configured in the working part 130 so that the working part 130 is enclosed in the connecting structure of the special-shaped nut 200, which helps to improve the mechanical strength of the special-shaped nut wrench 100.

[0037] See also Figure 1 and Figure 2 In order to improve the convenience of operating the special nut wrench 100, the handle portion 120 includes a first handle 121 and a second handle 122 respectively connected to the working portion 130, and the first handle 121 and the second handle 122 are arranged opposite to each other.

[0038] Optionally, the first handle 121 and the second handle 122 are integrally formed with the working portion 130 .

[0039] Optionally, the first handle 121 and the second handle 122 are respectively threadedly connected to the working part 130 .

[0040] Specifically, the mating portion 131 includes two first grooves 131a, both of which are disposed toward the avoidance opening 130a. The first grooves 131a have two continuous openings and are disposed on either side of the working portion 130. It is understood that the provision of the two first grooves 131a can improve the ease of use of the special-shaped nut wrench 100, facilitating use of the special-shaped nut wrench 100 from both sides.

[0041] Specifically, the matching portion 131 further includes two second grooves 131 b , which are symmetrically arranged on both sides of the first groove 131 a , and the second grooves 131 b pass through both sides of the working portion 130 .

[0042] It is understood that the second groove 131b is provided on both sides of the working portion 130, that is, the second groove 131b has three continuous openings. It is also understood that the provision of the second groove 131b further expands the adaptability of the special-shaped nut wrench 100.

[0043] In a more specific embodiment, the first handle 121 and the second handle 122 are arranged on the same axis; the two first grooves 131 a are arranged in the middle of the working part 130 , and the two second grooves 131 b are respectively arranged close to the first handle 121 and the second handle 122 .

[0044] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
