The invention relates to a portable sleeve thread processing device. The portable sleeve thread processing device comprises a device housing, a hoisting point, a device rotating position, a turning assembly and a hydraulic power supply system, wherein the device rotating position and the turning assembly comprises a rotating positioning shaft, a numerical control turning assembly and a numerical control vehicle buckle assembly; the hydraulic power supply system comprises a hydraulic motor, an external clamping oil cylinder, an internal supporting oil cylinder and a mechanical limiting cylinder; the external clamping oil cylinder is horizontally fixed to the tail end of a framework; the internal supporting oil cylinder is horizontally fixed to the inner side of the middle part of the framework; the mechanical limiting cylinder is longitudinally fixed to one side of the internal supporting oil cylinder; the rotating positioning shaft is fixed to the inner side of the tail end of the framework; the numerical control turning assembly corresponds to the numerical control vehicle buckle assembly, and the numerical control turning assembly and the numerical control vehicle buckle assemblyare arranged at the upper end and the lower end of the inner side of the framework; and the hydraulic motor is connected with the external clamping oil cylinder, the internal supporting oil cylinderand the mechanical limiting cylinder. The portable sleeve thread processing device disclosed by the invention has the advantages of being simple in structure, low in floor occupation, low in cost, lowin requirement for working environment, and wide in processing range, and can perform field operations; during specification switching, replacing a tool is not needed, so that time is saved, and theworking efficiency is improved; in the operation course, a pipe body does not rotate, so that the danger coefficient of the processing operation is reduced.
