[0031] The specific working principle and use method of the utility model are as follows:

[0032] The utility model provides a bolt with an anti-corrosion function. When in use, two objects that need to be fixed are connected through the bolt column 4. After the connection, according to the remaining leaked length of the bolt column 4, the positioning screw 8 is rotated by rotating the rotating head 7, so that the positioning screw 8 is separated from the threaded hole 14. After separation, the square shielding frame 9 can slide on the surface of the square shielding block 5 through the cooperation of the limiting slider 13 and the limiting slide groove 12, so that the shielding length can be adjusted according to the remaining leaked length of the bolt column 4. After adjustment, the positioning screw 8 is matched with the corresponding threaded hole 14 at this time by reverse rotation, and enters the threaded hole 14 to limit the square shielding block 5 and the square shielding frame 9. Under the action of the threaded through groove 10, the square blocking block 5 is threadedly connected to the surface of the remaining leaking part of the bolt column 4. The setting of the sealing gasket 15 can improve the sealing effect between the square blocking block 5 and the object, so that the remaining leaking part of the bolt column 4 can be blocked. By matching the blocking threaded tube 1 with the threaded column, the circular blocking cover 2 blocks the bolt cap 11. The setting of the sealing gasket 3 can improve the sealing between the circular blocking cover 2 and the object. Through the above steps, the bolt cap 11 and the leaking part of the bolt column 4 after connecting the object can all be blocked, which can effectively prevent external objects from directly contacting the bolt body, greatly increasing the corrosion resistance of the bolt and improving practicality.
