The invention relates to a mutual inductor conveying device, in particular to a mutual inductor conveying device with a tool plate pull-open mechanism. A current tool plate is directly provided with atool plate pull-open mechanism structure, the size is huge, and cost is high. The mutual inductor conveying device comprises a tool plate and the pull-open mechanism which are arranged in a separatedmanner. The pull-open mechanism comprises a base used for being fixed to an assembly line station, a bottom plate arranged on the top face of the base, and a movable platform which is arranged abovethe bottom plate and is capable of moving front and back on the bottom plate, and a power device used for driving the movable platform to move front and back is arranged in the middle of the bottom plate. Two pull plate assemblies which stretch out forwards and are used for backwards pulling push blocks of the tool plate are arranged at the front end of the movable platform. The tool plate and thetool plate pull-open mechanism in the technical scheme are arranged in the separated manner, and the production cost and the maintaining cost are effectively reduced; and through the tool plate pull-open mechanism, the tool plate can be rapidly and conveniently pulled open, two mutual inductors can be accurately and conveniently placed at the same time, and the work efficiency is improved.
