In the fourth variation of the second embodiment, the second pivot section 122 of the handle member 120 and the first pivot section 111 of the pulling member 110 are pivotally turnably connected together via a shaft; and the pull-out aiding device 100 further includes an elastic element 160. The elastic element 160 is fitted on around the shaft to elastically push against the pulling member 110 and the handle member 120. Therefore, when the handle member 120 is opened and not held in place by a user, the handle member 120 is automatically turned by a spring force of the elastic element 160 to the closed position.
Further, the handle member 120 includes a limiting section 124, which is located adjacent to the closing edge of the pressing section 121. In this case, the first partitioning wall 210 is correspondingly provided with a mating limiting section 216. The limiting section 124 can be extended through the mating limiting section 216 and hooked thereto, so that the handle member 120 is stopped from moving relative to the first partitioning wall 210.
