Abstract: A button structure includes a switch, a shell, an elastic member, a button and at least one adjustable limiting member. The elastic member includes a fixing portion, a compressive portion and an elastic portion. The fixing portion is connected to the shell. The compressive portion is configured to abut against the switch. The elastic portion is connected between the fixing portion and the compressive portion. The elastic portion is suitable for deformation. The button is connected to the compressive portion, and the compressive portion is located between the button and the switch. The adjustable limiting member is disposed on the button, and is configured to abut against the elastic portion. The adjustable limiting member adjustably protrudes for a length toward the elastic portion relative to the button.

Abstract: A hand-held package box and a developed plate thereof are provided. The package box includes a box body, a first plate, a second plate and a third plate. The third plate is connected to the box body, and the second plate connects the first plate and the third plate. The first plate has a first folded sheet, and the second plate has a second folded sheet. A position of the first folded sheet and a position of the second folded sheet are symmetrical with respect to a folding line between the first plate and the second plate. When the first plate is folded to a position between the second plate and the third plate, a folding line of the first folded sheet corresponds to a folding line of the second folded sheet, so that the first folded sheet and the second folded sheet, after being folded, form a handle.

Abstract: A clamping device includes two handles pivotally connected with each other and each having a first end and a second end, and two clamping members each detachably mounted on the first end of a respective one of the two handles by a quick release mechanism. Thus, the clamping members are detachably mounted on the handles by the quick release mechanism, so that the handles can co-operate with clamping members of different specifications and shapes according to different requirements, thereby facilitating a user operating the clamping device to clamp workpieces of different specifications and sizes.

Abstract: An agent installed on a server reclaims one or more reclaimable off-site copy storage volumes and one or more reclaimable on-site copy storage volumes. To this end, the agent identifies each reclaimable off-site copy storage volume, runs a plurality of threads to collectively copy each data object of the identified reclaimable off-site copy storage volume(s) that is stored within one or more primary storage volumes to one or more one on-site target copy storage volumes, identifies each reclaimable on-site copy storage volume, and runs the plurality of threads to collectively transfer each data object of the identified reclaimable on-site copy storage volume(s) to the on-site copy target copy storage volume(s).
