Description

Technical Field

[0001] The utility model relates to the technical field of automobile luggage rack installation, in particular to a nut tightening device for an automobile luggage rack. Background Art

[0002] A roof rack is a device mounted on the roof of a car. Its main functions and features include: Function: Increase cargo space; when interior space is limited, a roof rack can be used to store bulky items such as suitcases, bicycles, and skis. Especially for long-distance trips or outdoor enthusiasts, a roof rack provides additional storage options, greatly enhancing the vehicle's practicality. It also enhances the vehicle's appearance; it can add a sporty, off-road feel to the car, making it look more stylish and impressive. Different styles of roof racks can be designed to complement the vehicle's overall styling, enhancing its individuality. Types: Split rail racks typically consist of two parallel rails with a space between them. Their advantages are simple structure, easy installation, and the ability to be removed at any time. Split rail racks are a common type suitable for most car models. Integrated rail racks: Integrated rail racks integrate more tightly with the vehicle body, creating a more streamlined and natural look. They are generally stronger and can withstand greater weight. However, the installation of an integrated longitudinal rail rack is relatively complex and may require specialized expertise. Some models, in pursuit of a simpler design, do not feature a traditional longitudinal rail rack. In these cases, an adhesive-type rack can be an option, which attaches to the roof using glue or suction cups. While adhesive racks offer the advantage of being easy to install and harmless to the vehicle's structure, they also have a relatively weak load-bearing capacity. With the development of society, tightening equipment is often required when securing the nuts of a vehicle's roof rack.

[0003] Existing devices, such as CN216464296U, include a multi-size internal and external hexagonal wrench, comprising a wrench handle and a wrench head connected to one or both ends of the handle. The wrench head includes a first wrench head having a regular hexagonal through-hole, a second wrench head disposed within the regular hexagonal through-hole of the first wrench head, a regular hexagonal through-hole disposed within the second wrench head, and so on through the third to nth wrench heads. The nth wrench head is a solid internal hexagonal wrench head, with a gap between adjacent wrench heads. A through-hole is disposed on each of the two opposing side walls where the regular hexagonal through-hole of the first wrench head is located. The nth wrench head has two through-holes disposed along its length. The remaining wrench heads each have opposing through-holes on the opposing side walls, with the two through-holes on the same side wall corresponding to the two second through-holes on the nth wrench head. The utility model also includes a pin that can be inserted and removed through all the wrench heads. This utility model is convenient to carry and use.
