Abstract: An improved alternating current electrical socket structure includes a main enclosure in which are installed two lateral mounting blocks and one central mounting block; each mounting block has matching notch sections and tower sections, such that when the aforesaid lateral and central mounting blocks are aligned conductor strips can be positioned and securely held within the socket structure by the surfaces formed by the notch and tower sections of the lateral and central mounting blocks. The resulting configuration at the same time enables formed folds in the conductor strips to serve as tight receptacles in which the flat pins of an alternating current plug can be inserted tightly.

Abstract: An improved folding bicycle comprising a folding hinge mechanism as well as a set of foldable handle-bar and a collapsible seat structure. During normal use, the folding hinge mechanism is easily associated with multi-securing effect to ensure the safety of ride. While stored, it can be alternatively unlocked and separated manually, enabling the bicycle to be folded up for reducing the storing room. Furthermore, the set of handle-bar and saddle adjusting device can be used to simply adjust the dimensions of the bicycle to meet the requirement of any use.

Abstract: A folding basket having an upper frame and a lower frame and first and a second fences rotarily connected to the upper and lower frames, wherein the second fences are provided with hinge-like joint structure in their middle portions, permitting the basket to be easily folded up and assembled, and, furthermore, the bottom fence of the basket can be easily replaced with a new one when damaged.
