The invention provides a retractable vehicle steering column sleeve. The retractable vehicle steering column sleeve comprises an upper column sleeve and a lower column sleeve. One end of the lower column sleeve extends into the upper column sleeve to be mounted together in a sleeving mode. The retractable vehicle steering column sleeve is characterized in that the outer wall of the lower column sleeve is provided with axially-extending protrusion ribs uniformly distributed in the circumferential direction of the lower column sleeve, the protrusion ribs on the outer wall of the lower column sleeve are in interference fit with the inner wall of the upper column sleeve, a limiting portion in inner and outer diameters larger than those of other portions is formed at the lower end of the lower column sleeve through reaming, and the inner and outer diameters of the lower half portion of the upper column sleeve are correspondingly larger than those of the upper half portion of the upper column sleeve. Compared with existing common vehicle steering column sleeve retractable structures, the retractable vehicle steering column sleeve is simple in structure, constant in retraction force value, low in manufacturing cost and safe and reliable in use.
