The invention relates to a saddle tube with an inflating function. The saddle pipe comprises a saddle pipe body, an inner pipe sleeved with the saddle pipe body, a connecting hose connected with the interior of the inner pipe and an air nozzle connected with the end of the connecting hose. The upper end of the saddle pipe body is closed, the lower end of the saddle pipe body is open; an end coveris arranged at the lower end of the saddle pipe body; a supporting block is arranged at the lower part in the saddle pipe body; the inner pipe penetrates through the middle of the supporting block; apiston assembly is arranged at the upper end of the inner pipe; the inner pipe is slidably connected into the saddle pipe body, the interior of the inner pipe is slidably connected with a connecting hose; when the tire needs to be inflated, the saddle pipe is taken out of the bicycle body, inflation operation can be completed only through telescopic movement between the inner pipe and the saddle pipe body, the saddle pipe body also serves as an inflator body, the stroke of the piston rod is increased, the inflation efficiency is ensured, and meanwhile the bicycle inflator and the bicycle are integrally designed, so that the purposes of being convenient to carry and use are achieved.
