The mechanical protection mechanism comprises an inner epoxy pipe, a presoaked epoxy resin glass filament bundle high temperature solidified layer, an outer epoxy pipe and stainless steel flanges which are coaxial and fixedly connected with equal heights from inside to outside. The conductive coil is a stainless steel wire single layer spiral winding with a certain screw pitch. The stainless steel wire single layer spiral winding is wound onto the inner epoxy pipe and placed in a glass sinter layer. The stainless steel flanges are packaged at two ends of the outer epoxy pipe through pins. Two wire ends of the stainless steel wire single layer spiral winding are led out from the stainless steel flanges at two ends. The conductive part of the resistor is formed after a whole stainless steel wire is cold-wound. Leading-out wires are led out from the stainless steel wire directly, and no any transition points or welding points are formed. The mechanical protection mechanism has no loose fixing fastening parts and the operation reliability is raised greatly.
