The invention provides an automatic clamping type safety power strip. The automatic clamping type safety power strip comprises a casing, a square-hole frame, a panel, an unlocking frame, conductive modules, a double-sided bracket and a single-sided bracket and is characterized in that the square-hole frame is mounted at the middle of a front portion of the casing, the middle of the square-hole frame is provided with the panel, the panel is provided with jacks, a back portion of the square-hole frame is equipped with the double-sided bracket and the single-sided bracket, left and right sides ofthe double-sided bracket are equipped with the conductive modules, a front end of the single-sided bracket is equipped with one conductive module, and each conductive module respectively correspondsto one jack. Through setting an extension spring, a swing rod and a contact copper piece, a plug can be made to reduce friction with the contact copper piece during insertion, generation of sparks isreduced, when the plug is about to be inserted to a bottom portion of the jack, the relatively large pressure can be instantaneously generated by the tension spring and the swing rod for a plug metalpiece, electrical conductivity between the contact copper piece and the plug metal piece is enhanced, and various hidden dangers caused by poor contact of the plug can be prevented.
