The application relates to a power taking connecting device, a first clamping seat and a second clamping seat are fixedly connected to form a wire row main body for clamping a power distribution cabinet, the first clamping seat is provided with an opening, when power is taken, the wire row is accommodated between the first clamping seat and the second clamping seat through the opening, since the opening can be directly inserted into the wire row, the operator does not need to stretch hands into the power distribution cabinet to realize power taking, however, the connection between the wire row and the first clamping seat and the second clamping seat is not close, a clamping block is needed to clamp the wire row between the first clamping seat and the second clamping seat, at this time, only the rotation rod is needed to push the sliding block to move to make the clamping block move, when the clamping block moves, the distance between the wire row and the second clamping seat will be reduced, and then the wire row is closely attached to the second clamping seat, specifically, the rotation rod extends to outside the power distribution cabinet, when the rotation rod is rotated, the rotation rod pushes the sliding block to extrude the second inclined surface of the clamping block through the first inclined surface, the sliding block relatively moves along the second inclined surface, the distance between the wire row on the clamping block and the second clamping seat is reduced, and then the wire row is clamped.
