The invention discloses an electric pole vertical state quick detecting and resetting device for maintenance. The device comprises a base which is arranged transversely, a rear limiting device and a front limiting device are arranged at two ends of the base, a swinging barrel capable of swinging back and forth is hinged in a supporting section of the base, a supporting device is inserted into the swinging barrel and locked with a middle upper section of an electric pole through a locking device hinged by swinging up and down, a power input end of the supporting device is in transmission connection with a power device through a bendable transmission hose, a handle is fixedly arranged on a supporting seat, and a protecting cover expanding outwards is fixedly arranged at the inner end of the handle. The electric pole vertical state quick detecting and resetting device has the advantages that soil and stone on an orthotopic side of the electric pole can be quickly excavated, dust intrusion can be prevented, the electric pole can be corrected quickly, the tool is time saving, labor saving, firm in fixing, small in size and convenient to carry, and one person can correct the electric pole independently, so that correcting efficiency is high and breaking of the electric pole can be avoided.
