The invention relates to the technical field of clamps, in particular to a full-circumference tensioning device which comprises a mounting disc, a plurality of driving push blocks and a plurality of driven push blocks. The driving push blocks and the driven push blocks are sequentially arranged at intervals, are distributed in a circumferential mode on the whole and are slidably connected to the mounting disc, the sliding directions of the driving push blocks and the driven push blocks are different radial directions of the same circle center, and the peripheral faces of the driving push blocks and the driven push blocks are arranged to be in an arc shape. A transmission inclined plane group is arranged between the driving push block and the driven push block; when the driving push block slides outwards to the outer expansion limit position, the outer circumferential face of the driving push block and the outer circumferential face of the driven push block define a whole circle, and the outer circumferential
