Abstract: A battery fastening structure includes an isolation unit and a conduction unit. The isolation unit opens a through-hole. The isolation unit has at least one combination unit. At least two battery fastening structures are fastened and combined by virtue of at least two combination units of the at least two battery fastening structures being buckled. Two opposite ends of the through-hole extend outward to form a first connecting hole and a second connecting hole, respectively. Two opposite ends of the conduction unit are received in the first connecting hole and the second connecting hole, respectively. The first connecting hole is designed to make one end of the conduction unit electrically connected with the positive pole of the battery, and the second connecting hole is designed to make the other end of the conduction unit electrically connected with the negative pole of the battery.

Abstract: A portable cable assembly includes a first connection port, a second connection port, a cable, an absorptive element, a shell and a sleeve. The first connection port has a first base portion and a first mating portion, the first base portion defines a containing groove in an outer surface thereof. The second connection port has a second base portion and a second mating portion. Two ends of the cable are connected with the first base portion and the second base portion. the absorptive element is accommodated in the containing groove. The shell surrounds the first base portion and the absorptive element. The sleeve is capable of sliding to sleeve the first connection port and the second connection port therein, and the sleeve can be absorbed on the shell by the absorptive element.

Abstract: A clipping communication device includes a first clipping arm unit, a second clipping arm unit, an antenna module and a pivot unit. The first clipping arm unit includes a first force exerting portion and a first clipping portion. The second clipping arm unit has a second force exerting portion and a second clipping portion. The first force exerting portion is disposed corresponding to the second force exerting portion, and the first clipping portion is disposed corresponding to the second clipping portion. The antenna module is disposed in the first clipping arm unit. The pivot unit pivots on the first clipping arm unit and the second clipping arm unit.
