The utility model relates to a portable tool for detecting the air tightness of a welding spot, which comprises a dust blowing gun, a suction cup is arranged at the end part of a gun barrel of the dust blowing gun, and an air passage in the gun barrel is communicated with an inner cavity of the suction cup. In order to solve the problems that in the prior art, in the prior art, workers need to repeatedly carry leakage detection parts up and down on a special leakage detection tool, and operation is tedious, by adopting the portable tool, when welding spots with air tightness failure on the power battery box parts need to be found and repaired, the parts can be directly carried to a repair frame, and the work efficiency is greatly improved. Single-point leakage detection and repair state confirmation can be directly carried out on the repair frame without using a special leakage detection tool, so that a leakage detection part does not need to be repeatedly carried up and down, the operation is simple and conv
