The utility model relates to a surface quenching processing device for large and medium-sized steel sheets, in particular to a retractable surface quenching inductor, aiming to overcome the defects in the prior art that the an integrated device is used as indicator for surface induction quenching of sheet pieces, so the bending deformation due to the large size of the piece always causes contact and spark between the pieces and the indicator when the size of the piece is large, which damages the indicator and surface of the pieces. The utility model is characterized in comprising a left induction coil and a right conduction coil; two connecting sleeves are welded on two induction coils; a wire is used to weld the connecting sleeves, so as to form an integral path; one end of a connecting column is fixedly connected with a right support piece via a blind hole thread, while the other end is arranged through a through hole of a left support piece and positioned on the left support piece via a pin roll; a spring
