The invention discloses an electric car mover with dual self-locking. The electric car mover comprises a bottom frame, a front holding clamp structure and a seven-connecting-rod lifting mechanism, wherein walking universal wheels are arranged below the bottom frame; the front holding clamp structure is of a stepped structure fixed at the inner side of a front frame; the seven-connecting-rod lifting mechanism is arranged at the inner side of a rear frame and comprises a large hinged support fixed on the rear frame, a roller parallel to the rear frame, and two seven-connecting-rod telescopic units hinged to the two ends of the roller; a pedal is hinged to the large hinged support and optical axes are arranged on two sides of the pedal; each seven-connecting-rod telescopic unit comprises a rotating rod, a self-locking swinging connecting rod set, a self-locking lower connecting rod set, a long connecting rod and a propelling connecting rod which are hinged to each other and are self-locked in the telescopic state respectively; the optical axes are driven to rotate through stepping on the pedal, and the seven-connecting-rod telescopic units are driven to stretch, so that lifting and parking of electric wheels are realized. According to the electric car mover, the movement in any direction and any distance can be effectively realized when the electric car is got and the wheels are clamped and fixed, and management of the electric car is greatly facilitated.
