The invention provides a parallel support-type embedded pole, which comprises an epoxy resin shell, an electric field shielding case, a parallel support screw connector, a copper conducting rod, a copper insert, a vacuum arc-extinguishing chamber, an arc-extinguishing chamber support plate, pins and a conductive nut, wherein the vacuum arc-extinguishing chamber and the copper conducting rod are embedded into the epoxy resin shell, the volume of a vacuum load switch-fuse composite apparatus is reduced and one part of the arc-extinguishing chamber support plate is cast into the epoxy resin shell, so that the overall switch is smaller and layout is more compact. The electric field shielding case is cast into the embedded pole, and the embedded pole is matched with the parallel support screw connector connected with the electric field shielding case and bolts and is fixed between an upper beam and a middle beam of the composite apparatus through a parallel support-type installation surface in parallel to the vacuum arc-extinguishing chamber and the copper conducting rod of a main loop, so that the problem of uneven high-voltage electric field distribution in the embedded pole is solved. The parallel support-type embedded pole has a good insulation level; parts and raw materials are reduced; and the production cost is reduced.
