The invention relates to a clamping-type disassembly and assembly tool for a 35kV fusion tube. Compared with the prior art, the clamping-type disassembly and assembly tool has the advantage that the defect of absence of a disassembly and assembly tool for a fusion tube body is avoided. According to the clamping-type disassembly and assembly tool, a left hoop is arranged at the other end of a left rod and a right hoop is arranged at the other end of a right rod; the left hoop is detachably arranged on the right hoop; the diameter of a circle which is formed by arranging the left hoop and the right hoop together is smaller than that of each porcelain group; a threaded rod is arranged on a mounting base via a thread in a penetrating manner; and a crank is arranged at one end of the threaded rod; and the top part of a pressing block is arranged at the other end of the threaded rod and, the pressing block is located between the left rod and the right rod and the bottom part of the pressing block abuts on a tube cap of the fusion tube body when the threaded rod moves downwards. By the clamping-type disassembly and assembly tool, the disassembly and assembly difficulty of the fusion tube is simplified; and disassembly and assembly of the overall fusion tube can be finished through one-man operation.
