[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] In the description of the present disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "top," "bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present disclosure and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] It should also be noted that the standard parts used in this application document can all be purchased from the market, and can be customized according to the description in the specification and drawings. Unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to the specific circumstances, and, in the absence of clear limitations, machines, parts, and equipment can all adopt conventional models in the prior art.
[0018] In this document, the term "comprising" is intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0019] Example: Reference Figure 1-2 The nut 1 is provided with a hexagonal slot 3, and a hard cover 4 is installed on the nut 1. The hard cover 4 is detachably mounted on the outside of the nut 1. The hard cover 4 includes a hexagonal plug 5 fixedly connected to the bottom end thereof. The hexagonal plug 5 is plugged into the inside of the hexagonal slot 3, and an elastic rubber block 6 is fixedly connected to the outer walls of the opposite sides of the hexagonal plug 5. The inside of the hexagonal slot 3 is provided with two small notches 7, and the small notches 7 are correspondingly plugged with the elastic rubber block 6. The bottom end of the hard cover 4 is fixedly connected to an elastic rubber ring 8, and the elastic rubber ring 8 is sleeved on the outside of the nut 1. The rust-proof screw structure provided by the utility model facilitates shielding and waterproofing of the end of the nut by arranging a hard cover and a hexagonal plug.
