The invention discloses an acid-base-resistant and corrosion-resistant jack. The acid-base-resistant and corrosion-resistant jack comprises a jack hydraulic cylinder, a piston arranged inside the jack hydraulic cylinder and a piston rod arranged on the piston. A jack hydraulic cylinder outer zinc-plated layer is arranged on the external surface of the jack hydraulic cylinder, a jack hydraulic cylinder outer corrosion-resistant paint layer is further arranged on the external surface of the jack hydraulic cylinder outer zinc-plated layer, a piston rod inner zinc-plated layer is arranged on the external surface of the piston rod, a piston rod outer zinc-plated layer is arranged on the external surface of the inner zinc-plated layer on the piston, and a groove is formed in the bottom of the jack hydraulic cylinder. Through the mode, the acid-base-resistant and corrosion-resistant jack is simple and reasonable in structure, good in acid-base-resistance and corrosion-resistance performance and long in service life.
