In addition, some aspects of the utility model can be used alone, or used in any appropriate combination with other aspects of the utility model.

[0020] Embodiment 1

[0021] As Figures 1-4As shown, the first protective sleeve 1 is used for sleeving on the surface of the bolt, protects the tail part of the bolt, prevents direct contact with the water body, thereby reducing the risk of rust, the protective ring 2 and the second protective sleeve 3 are used for protecting the nut and the rod part of the bolt, preventing direct contact with the water body, thereby reducing the risk of rust, and can prevent deformation due to rust, ensure that the bolt can be normally disassembled, the sealing ring 4 is used for sealing the gap between the fastener and the first protective sleeve 1 and the protective ring 2, preventing the occurrence of water seepage, the limiting groove 5 is used for limiting the connecting ring 6, and can provide a movable space for the connecting ring 6, the connecting piece 7 is used for connecting the two connecting rings 6, thereby connecting the first protective sleeve 1 and the protective ring 2, ensuring that the first protective sleeve 1 and the protective ring 2 are not lost when used together.

[0022] As shown in Figures 1-4 , the first protective sleeve 1 is used for sleeving on the surface of the bolt, protects the tail part of the bolt, prevents direct contact with the water body, thereby reducing the risk of rust, the protective ring 2 and the second protective sleeve 3 are used for protecting the nut and the rod part of the bolt, preventing direct contact with the water body, thereby reducing the risk of rust, and can prevent deformation due to rust, ensure that the bolt can be normally disassembled, the sealing ring 4 is used for sealing the gap between the fastener and the first protective sleeve 1 and the protective ring 2, preventing the occurrence of water seepage, the limiting groove 5 is used for limiting the connecting ring 6, and can provide a movable space for the connecting ring 6, the connecting piece 7 is used for connecting the two connecting rings 6, thereby connecting the first protective sleeve 1 and the protective ring 2, ensuring that the first protective sleeve 1 and the protective ring 2 are not lost when used together.

[0023] Embodiment 2
