The invention discloses an inversely fixed bollard which comprises a bottom plate, wherein an inversely fixed bollard body is arranged on the bottom plate, oblique fixed columns are arranged on the bottom plate, fixing holes are formed in the oblique fixed columns, and the oblique direction of each oblique fixed column is the same as the pull direction. According to the invention, the structural design is reasonable; and fixed bolts can be obliquely fixed through the oblique columns so as to reduce the included angle between the each fixed bolt and the pull direction, so that the shearing force of the fixed bolts is reduced, the service life is prolonged and the maintenance cost is reduced.
