Abstract: The utility model discloses a convenient inflation nail of dismantling, including screw and inflation cover, the inflation cover sets up the screw outside, the screw top sets up the dog, screw upper portion sets up circular inflation hole, the downthehole wall that expands sets up anti -skidding screw thread, inflation hole both sides correspondence sets up the slotted hole, the downthehole vertical section that inserts that expands is trapezoidal inflation core, inflation core cross section is square, the inflation core with the both sides of inflation hole contact are the arc and correspond the antiskid screw thread sets up the tight screw thread in top, inflation core top sets up the boss. The inflation cover sets up the crescent barb type screw thread of size from bottom to top. The utility model discloses a frictional force between inflation cover increase screw and the pore wall prevents inflation nail roll -off from the hole in, and the inflation core plays further stretching effect to the screw, has strengthened the frictional force between screw and the pore wall, and through rotatory inflation core alright will expand the nail and remove, easy operation is convenient, the practicality is fine.
