Supporting device

Abstract

A supporting device includes two slide rails, a first predetermined feature and a second predetermined feature. The two slide rails are displaceable relative to each other. The first predetermined feature is arranged on one of the two slide rails. The second predetermined feature is arranged on the other one of the two slide rails. When one of the two slide rails displaces along a predetermined direction, the first predetermined feature and the second predetermined feature abut against each other for reducing a displacement speed of the one of the two slide rails along the predetermined direction. The supporting device further includes a first bracket and a second bracket displaceable relative to each another. The two slide rails are arranged on the first bracket.
