The invention discloses a universal bearer for fixing a portable indenter in a pipeline type structure. The universal bearer includes a bear panel, an axial fixing assembly for fixing a surface of the pipeline type structure, radial guide assemblies, connection members for connecting a base of the portable indenter, and a controller; an opening for testing the pipeline type structure is formed in the center of the bearer panel; the connection members are symmetrically arranged on the upper surface of the bearer panel at the front side and the back side of the opening; the radial guide assemblies are symmetrically arranged on the left side and the right side of the bearer panel; the controller is arranged on the bearer panel; and each radial guide assembly includes a guide rail, a clamping claw connector, a clamping claw, a horizontal driving mechanism for driving the clamping claw to move horizontally, and a vertical telescoping mechanism for allowing the clamping claw to stretch vertically. The universal bearer for fixing the portable indenter in the pipeline type structure can meet the environment demands of different project sites.
