Pipe sander Technical Field The utility model belongs to the technical field of pipe surface grinding treatment, and particularly relates to a pipe sander. Background When the existing pipe is subjected to grinding treatment on the outer surface of the pipe, the pipe is manually held by an operator, then the surface of the pipe is close to a grinding belt or a grinding wheel of a grinding machine to be subjected to grinding treatment, and in the grinding process, the operator also needs to rotate the pipe to perform circumferential grinding treatment on the outer surface of the pipe, so that the pipe is inconvenient to operate, the working efficiency is low, and the quality of the grinding surface of the pipe is not easy to guarantee. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a pipe sander with convenient operation. In order to achieve the purpose, the technical scheme includes that the pipe sander comprises a shell, a grinding pipe and a rotating shaft, wherein the grinding pipe and the rotating shaft are rotatably connected in the shell, the inner side surface of the grinding pipe is a grinding surface, a transmission connecting part connected with an external rotating device is arranged at the outer end of the rotating shaft, a driving gear is arranged at the inner end of the rotating shaft, a toothed ring is fixedly arranged at the outer side of the grinding pipe, teeth of the driving gear are meshed with teeth of the toothed ring, and two ends of the grinding pipe are exposed outside the shell. In the scheme, through rotating in the shell and being connected with the grinding pipe, during the use, can insert the tubular product that needs to grind into the grinding intraductal, then utilize outside rotating device such as electric drill to be connected through with transmission connecting portion transmission, drive the pivot by the electric drill and rotate, the pivot rotates simultaneously the driving gear also can follow the rotation, and the driving gear rotates and can drive the grinding pipe rotation in the ring gear, thereby make the inboard grinding of grinding pipe grind the processing facing tubular product surface, wait to grind after accomplishing, close the electric drill again, take out the tubular product that grinds from grinding intraductal, just can accomplish the grinding operation on tubular product surface. Because grind intraductal and tubular product outside shape matching to in the pipeline grinding process, operating personnel need not to rotate tubular product, grinds the pipe and also can carry out circumference grinding treatment to the tubular product surface, convenient operation, work efficiency is high, and grinds more evenly to the tubular product surface. Further, the grinding pipe comprises a pipe body rotationally connected in the shell, an annular grinding body arranged in the pipe body, a left end cover arranged at the left end of the pipe body and a right end cover arranged at the right end of the pipe body, wherein the toothed ring is fixedly arranged on the outer side of the pipe body, the inner side surface of the annular grinding body is a grinding surface, the annular grinding body is arranged between the left end cover and the right end cover, the left end cover and the right end cover are provided with sockets corresponding to the hollow inner part of the annular grinding body, and the grinding surface of the annular grinding body is easy to wear after long-term use. The annular grinding body of the scheme is large in size and is used for grinding large-size pipes. In addition, the inside of the pipe body is provided with a limiting piece which can limit the rotation of the annular mill relative to the pipe body so as to ensure that the annular mill body can rotate along with the rotation of the pipe body and grind the pipe. Further, the limiting piece is a limiting bulge arranged on the inner side of the pipe body, the side wall of the annular grinding body is provided with a limiting notch which penetrates through two ends of the annular grinding body, the limiting bulge is arranged in the limiting notch, so that the limiting bulge can stop the annular grinding body from rotating relative to the pipe body, the annular grinding body and the pipe body synchronously rotate, the limiting notch is arranged to penetrate through two ends of the annular grinding body, and therefore the annular grinding body can move left and right to be separated from the pipe body without affecting replacement operation of the annular grinding body.
