The invention discloses an externally-expanding gradual-change inflatable docking unit used for outer space. The docking unit comprises a docking pipeline, wherein a connecting flange is installed at a first end of the docking pipeline, multiple sets of stopping blocks are sequentially arranged on the docking pipeline from a second end to the first end, the intervals between the stopping blocks are gradually changed, each set of stopping blocks is composed of two stopping blocks arrayed closely, a tubular elastomer is installed between every two adjacent sets of stopping blocks in a sealed mode, the tightness degrees of the multiple elastomers are identical or basically identical, and multiple through holes communicated inside and outside are formed in the wall of the part, between the first set of stopping blocks and the last set of stopping blocks, of the docking pipeline. The elastomers are installed on the docking pipeline in the sealed mode, in this way, stability of the whole docking unit is enhanced after docking, and a controlled object is reliably and easily operated. By the adoption of the elastomers which are gradually increased or decreased in length and uniform in tightness degree, the docking unit can adapt to various docking objects of different diameters, and then the application range of the docking unit is enlarged.
