[0001] This utility model relates to the field of bicycle accessories technology, specifically to a safety hook and the bicycle thereof. Background Technology
[0002] The bicycle safety hook is an important component at the rear of a bicycle, primarily used to connect and secure the rear wheel. It also handles the installation and adjustment of various other parts, ensuring stability and safety while riding. Typically made of materials such as aluminum alloy, it possesses a certain degree of toughness and deformability. In the event of a crash, the hook can absorb impact, protecting critical components such as the derailleur from damage.
[0003] Currently, tail hooks tend to bend and deform after a certain period of use, requiring disassembly, replacement, or correction. Disassembly involves removing the rear wheel and axle, which is quite troublesome. Furthermore, existing bicycles lack a structure to secure the rear wheel axle, which can lead to axle rotation during riding. There is an urgent need to design a safety hook and a bicycle to solve these problems. Utility Model Content

Then, the corresponding brake mechanism 4 can be installed on the left mounting bracket 2, and the hook 8 is installed in the right mounting bracket 1. The derailleur can be installed on the hook 8 for use. After installation, it is fixed by the fixing plate 11, so that the positioning mechanism 13 positions the fixing plate 11. At this time, the axle fixing hole 12 on the fixing plate 11 will correspond to the axle groove 3, pushing the installation... After the upper fixing plate 11 is installed, the axle 22 will pass through the axle fixing hole 12. The fixing plate 11 on the right mounting bracket 1 will fix the fixing block 7 and the hook 8. When it is necessary to remove the fixing block 7 and the hook 8, simply remove the fixing plate 11 on the right mounting bracket 1. The fixing block 7 and the hook 8 can be removed and replaced without separating the right mounting bracket 1 and the axle 22. When riding, the fixing plate 11 will fix the axle 22 through the axle fixing hole 12, and the positioning mechanism 13 will fix the fixing plate 11 to prevent the axle 22 from rotating.
