[0006] Preferably, the reinforcing mechanism comprises a fixed block, the outer wall of the fixed block is in abutment with the connecting groove, the upper end of the fixed block is fixedly connected with an internal thread cylinder, and the inner wall of the internal thread cylinder is processed with an opening.

[0007] Preferably, the outer wall of the internal thread cylinder is in sliding connection with the convex strip, and the upper end of the extension column is connected with a fixing mechanism.

[0008] Preferably, the fixing mechanism comprises a threaded ring, the outer wall of the threaded ring is in threaded connection with the extension column, the upper end of the threaded ring is fixedly connected with a connecting ring, and the upper end of the connecting ring is fixedly connected with a rubber intercepting ring.

[0009] Preferably, the upper end of the connecting ring is fixedly connected with a nut body, and the upper end of the nut body is fixedly connected with a cap.

[0010] Preferably, the outer wall of the rubber interception ring is movably connected with the extension column.

[0011] The high-strength automobile cap-shaped nut has the advantages that the threaded ring is separated from the extension column by the nut body, lubricating liquid can be dripped into the exposed upper end of the internal thread cylinder of the extension column for lubrication, the gasket ring and the extension column can be separated, the convex strip on the extension column is separated from the internal thread cylinder, the internal thread cylinder is pried by a flat tool through the opening on the internal thread cylinder, the internal thread cylinder is loosened and removed from the threaded part of the vehicle, and the cap-shaped nut is more convenient to disassemble.
