Beschreibung
Zusammenfassung:	The invention discloses an integrally-manufactured extension nut. A second pivot connector and a nut solid section are arranged on an extension nut body; the nut solid section is connected to the second pivot connector through a partially cylindrical solid section and a conical solid section; a screw crossing hole with aperture greater than major diameter dimension of a screwed hole is coaxially formed in the partially cylindrical solid section, and a material-saving window mould cavity is arranged on the partially cylindrical solid section and the conical solid section; a second pivot specially-shaped connecting hole perpendicular to a shaft axis of the extension nut body is formed in the second pivot connector; a second pivot positioning platform is arranged in a solid of the second pivot specially-shaped connecting hole; and adjacent positions of structural elements of the extension nut body are provided with circular-arc curved surfaces, circular-arc surfaces, cylindrical curved surfaces and the second pi
