PURPOSE: A portable multi-wrench tool is provided to install many nuts at the same time by rotating one main shaft engaged with many operating shafts by each bevel gear. CONSTITUTION: A portable multi-wrench tool comprises: a main shaft(10) installed in an air tool; many operating shafts(20) connected to the main shaft in a bevel gear mechanism(11); and a housing(30) rotating the main shaft and the operating shafts while covering the shafts. The bevel gear mechanism consists of: two bevel gears(13) installed in the lower portion of the main shaft and operating shafts; and connecting shafts(14) engaged with two bevel gears. The housing integrally covers the main shaft, the operating shafts and the bevel gear mechanism. Thus, when the main shaft is rotated, many operating shafts are rotated at the same time.
