Pull-out aiding device and chassis-wall module with pull-out aiding function

Abstract

A pull-out aiding device is configured for mounting on an object, in which a corresponding apparatus is mounted. The pull-out aiding device includes a pulling member and a handle member. The pulling member includes a first pivot section and an abutting section for abutting against the corresponding apparatus to move the latter forward. The handle member includes a second pivot section and an operating section. The second pivot section is pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section relative to the pulling member and brings the latter to move forward.
