A high-voltage cable argon arc welding metal sheath airtightness testing device comprises first pressing mechanisms, second pressing mechanisms, first adjusting pieces and second adjusting pieces, the first pressing mechanisms are arranged on the two sides of an airtightness detection station, and the second pressing mechanisms are arranged on the outer sides of the first pressing mechanisms. After the first adjusting part penetrates through the second pressing mechanisms and pushes the first pressing mechanisms to abut against the metal sheath, the second adjusting part tensions the two second pressing mechanisms so as to further press the metal sheath, an inflation mechanism is arranged above the second pressing mechanisms, the inflation mechanism is provided with a fastener, the inflation mechanism and the second pressing mechanisms are tensed through the fastener, and the inflation mechanism is provided with an inflation valve. The lower surface of the inflation mechanism abuts against the end face of the
