Abstract
The utility model discloses an internal nut expansion bolt which comprises an expansion pipe, a screw and a nut. The nut with a trapezoidal shape is arranged on the expansion end of the expansion pipe; a sub bolt is installed on the screw joint of the screw. The utility model has the following beneficial effects: as the trapezoidal nut is arranged on the expansion end of the expansion pipe, when the screw is tightened, the trapezoidal nut moves forward, which makes the expansion end of the expansion pipe expanded and fixed, and then the parts to be fixed are fixed by the sub blot. The advantages of the utility model are that the extended screw can not be seen, which has a good appearance and convenient disassembly.
