Drive connecting rod for high-voltage isolating switch

The utility model relates to a drive connecting rod for a high-voltage isolating switch, which consists of a positive screw bolt, a positive screw nut, a negative screw bolt, a negative screw nut and a connecting rod, wherein the connecting rod is a steel pipe with a hollow structure, and the two ends of an inner cylinder of the steel pipe with the hollow structure are provided with screw threads which are respectively connected with the bolts; and the left side of the connecting rod is provided with the positive screw bolt, and the right side of the connecting rod is provided with the negative screw bolt. The parts of the drive connecting rod is changed into the direct connection by the inner screw thread of the circular steel pipe from the original outer threaded connection, thereby preventing the usability from being influenced since the screw threads are corroded when the screw threads run for a long time. The length of the drive connecting rod is adjusted by an outer screw hot galvanizing bolt, so that the operation is simple and convenient.
