Disclosed are a nut wrench suitable for multiple sizes, comprising a nut clamping device (1) and an operating handle (2). The nut clamping device (1) is disposed on the operating handle (2); the operating handle (2) comprises a connecting ring fixing block (18), a power supply (19), a wrench operating support (20), a rubber handle (21), and sweat grooves (22). The sweat grooves on the rubber handle help a user to discharge sweat from the hand, thereby avoiding wet and slip due to too much sweat on the handle. The nut wrench is suitable for removal and installation of hexagonal nuts having different diameters, and is simple to operate and convenient to carry; when the nut wrench is used, the occurrence of cross-threading to a nut caused by mismatch between diameters of the nut and the wrench until the nut cannot be removed can be avoided, and the problems that existing nut wrenches on the market is low in efficiency, complex in structure, and inconvenient to maintain can be effectively solved. Also disclosed is a method for using the nut wrench.
