description The utility model relates to a centralizing device, in particular to a telescopic oil cylinder centralizing device. The telescopic oil cylinder righting device is composed of a rack, folding arms, a tension spring and a cylinder protection sleeve, the folding arms are installed on the two sides of the rack through pin shafts respectively, a tension spring assembling base is arranged on the portion, below the folding arms, of the rack, and the tension spring is installed on the tension spring assembling base through an adjusting bolt; a cylinder protection sleeve is arranged at the end of the folding arm on one side of the pin shaft, and the end of the folding arm on the other side of the pin shaft is connected with a tension spring. The telescopic oil cylinder centralizing device is simple in structure, convenient to use and capable of centralizing the piston rod of the telescopic oil cylinder, so that eccentric wear between the piston and the inner wall of the cylinder body and between the piston rod and an
