The invention discloses a guiding pipe with the long service life. The guiding pipe comprises a wall body and a guiding pipe body; the guiding pipe body is located at the top of the wall body; the bottom of the guiding pipe body is fixedly connected with a fixing block; the two sides of the fixing block are fixedly connected with mounting plates correspondingly; the top of the surface of the guiding pipe body is sleeved with a protective shell; a first baffle is fixedly connected to the top of an inner cavity of the protective shell; and a spring is fixedly connected to the bottom of the first baffle, and the bottom of the spring is fixedly connected with a second baffle. The wall body, the guiding pipe body, the fixing block, the protective shell, the first baffle, the spring, the second baffle, rubber blocks, fixing strips, the mounting plates, an anti-slip cushion, expansion bolts, mounting holes, tapping screws and locating holes are matched, thus the problem that when an existing guiding pipe is mounted, a pipe body is exposed, and thus the service life of the guiding pipe is shortened is solved, the guiding pipe has the advantage of long service life, and the economic loss of users is reduced.
