Abstract

The utility model provides a ladder-shaped plug sleeve, which comprises a sleeve body, a convex ring, a first step, a second step, and a third step. The upper end of the sleeve body is small and the lower end is big so as to form a ladder-shaped structure; the inner diameter is also the same, the upper end is small and is 3mm, and the lower end is big and is 6mm; the convex ring is arranged on the outer circumference of the middle and lower part of the small end; and the sleeve body is respectively provided with the first step, the second step and the third step from the top bottom, and the outer diameters are increased accordingly. The ladder-shaped plug sleeve is adopted to be matched with a plug-in to enable connection to be more stable.
