Scissor type disconnecting switch, conductive tube assembly thereof and conductive tube of scissor type disconnecting switch

The invention relates to a scissor type disconnecting switch, a conductive tube assembly thereof and a conductive tube of the scissor type disconnecting switch. The scissor type disconnecting switch comprises a fixed contact and a conductive tube assembly; the conductive tube assembly comprises a first conductive tube and a second conductive tube which are hinged together to form a cross shape; the first conductive tube and the second conductive tube respectively include a first tube body and a second tube body which are both provided with a movable contact; the first tube body has a hinging section hinged to the second conductive tube; the hinging section has an interval which is formed by baffles at two sides which are arranged at intervals along a hinging axis; the second conductive tube passes through the interval; the corresponding sides of the baffles at the two sides are provided with blocking side surfaces which are in blocking matching with the second conductive tube along thedirection of the hinging
