Abstract: A plug adapter with wireless transceiver module with universal plug & socket assembly is combined with a wireless transceiver module. Firstly, a wireless transceiver module is set into the portable plug adapter without worry about the difference of plugs; furthermore, it is possible to share wireless connection via either of 3G, 4G, WIMAX and WIFI. And, an input interface and at least one connection port are set externally and connected electrically to provide wired network input and output; if wireless signals are output via the wireless transceiver module, many users could share network resources. Additionally, a USB connector is connected with an electronic device for electric charging, thus realizing ease of use via the integrated design of the present invention.

Abstract: The automatic locking and releasing structure for a push-pull plug of this invention includes an upper case, a bottom case, a slider and push-buttons. The bottom case is suspended therein with two symmetrically arranged slide tracks that are each provided at the inside thereof with a wedge piece. The opposing sides of the slider are each formed with a resilient retaining arm, and the slider is movably provided between the two slide tracks. The free ends of the resilient retaining arms are movably attached to the push-buttons provided at the outside of the slide tracks. As such, when one manipulates the push-buttons to move along slide slots formed in the upper case and bottom case, the slider may be retracted or extended at the same time thereby subjecting the resilient retaining arms to assume a locking or releasing state with respect to the wedge pieces.

Abstract: The present invention provides a fiber coupler twister used in fused taper process, in which two round plates having a plurality of holes thereon are each placed in the troughs of two pedestals respectively, and can be rotated. When manufacturing a fiber coupler, a plurality of fibers are each passing through the plurality of holes on the two round plates respectively, and then rotate the two round plates, so as to form various fiber couplers with different twisting angles.
