Wherein, the second coupling section 127 is a hole, and the first coupling section 116 is a protruded body, a hook, a recessed body or a fastening body extended through the hole 127.

Further, as can be seen in FIG. 20, the rotation shaft portion 126 formed at an end of the handle member 120 has a cylindrical circumference 128, which is pressed against a bottom of the receiving recess 213 of the first partitioning wall 210, such that the pulling member 110 can be smoothly turned about the rotation shaft portion 126.

By operating the handle member 120 at the operating section 123, a user can turn the handle member 120 about the rotation shaft portion 126 to a position perpendicular or nonparallel to the first partitioning wall 210. Then, pull the operating section 123 to translate the same. At this point, the handle member 120 brings the pulling member 110 to move along with it, causing the abutting section 112 of the pulling member 110 to push the corresponding apparatus 300 forward, such that the corresponding apparatus 300 can be conveniently removed from the object.

Please refer to FIG. 21, in which a pull-out aiding device according to a variation of the third embodiment of the present invention is shown.
