Abstract: A bag set comprises a first bag unit combined with a second bag unit. The first bag unit includes a main bag body and a strap set. The main bag body has two first fasteners disposed on an outer surface. The strap set includes a first strap component having two ends connected with the main bag body, and a second strap component having a loop structure and one end connected with the main bag body. The second bag unit has two second fasteners to be attached to or disassembled from the two first fasteners selectively. When in use, the first strap component is hung diagonally on a shoulder of a user; and the second strap component is extended forward from the waist of the user to make the loop structure positioned in front side of the user, to pass the first strap component through the loop structure.

Abstract: A photographic assist apparatus of a mobile communications unit includes a tank, a shaft and a rod. A groove is formed at the bottom of the inner side of the tank. The shape of the groove is designed corresponding to the shape of the rod, for accommodating the rod. A first and a second button portions are disposed at two ends of the rod respectively. And a central portion is located between the first and the second button portions. The shaft is disposed in the groove. The rod has a hole located at the central portion thereof for the shaft setting through. When a user presses the first button portion, the rod is rotated to turn a small rotation angle by taking the shaft as an axis, to drive the second button portion moving, and the rotation angle is limited by the gap between the groove and the rod.
