[0034] Example 4:

[0035] The specific usage and function of this embodiment are described below:

[0036] When the present invention is used, first clean the dust inside the bolt hole 101; then place the elastic rubber column 302 and the steel gasket 303 on the outside of the fixed cylinder 201, and screw the galvanized nut 301 on the outside of the fixed cylinder 201 using the threaded structure, and use the square structure at the end of the fixed cylinder 201 to install the extension column 401 on the outside of the fixed cylinder 201, so that the fixed cylinder 201 squeezes the self-locking block 404, and the self-locking block 404 slides into the extension column 401 using its own bevel structure. When the end of the extension column 401 is in contact with the outside of the fixed cylinder 201, the self-locking block 404 slides into the square hole 202 using the reset rod 405 and the spring part, so that the extension column 401 and the fixed cylinder 201 are fixed, and the hexagonal structure at the end of the driving rod 402 slides into the connecting hole 204. The sealing disc 2 and the fixing cylinder 201 are then placed inside the bolt hole 101, with the auxiliary device 4 located outside the wall 1. The extension column 401 is fixed with a spanner, and the driving rod 402 is rotated with the handle 403. The driving rod 402 drives the threaded rod 203 to rotate, and the threaded rod 203 drives the threaded seat 205 to move horizontally through the guide block 206. The threaded seat 205 applies pressure to the driving disc 208 and the driving block 209 through the connecting rod 207, so that the driving block 209 drives the four sets of connecting seats 2010 to move outward simultaneously. The tapered structure at the end of the fixing column 2012 is then inserted into the wall 1, so that the sealing disc 2 and the fixing cylinder 201 are fixed to the bolt hole 101. The auxiliary ring 409 is then pushed forward. The auxiliary ring 409 drives the reset rod 405 and the self-locking block 404 to slide outward through the auxiliary seat 408 and the auxiliary rod 407, so that the self-locking block 404 slides out of the square hole 202. Then remove the extension column 401, and then use the hexagonal socket wrench to tighten the galvanized nut 301, so that the steel gasket 303 compresses the length of the elastic rubber column 302, and the diameter of the elastic rubber column 302 expands to squeeze and seal with the inner wall of the bolt hole 101, thereby achieving the effect of sealing the bolt hole 101.
