In a wireless transceiver device, a connector module has a coupling section with a first pivot part extending along a first pivot axis. A coupling base is formed with a first pivot hole that engages rotatably the first pivot part to permit relative rotation between the coupling base and the connector module about the first pivot axis, and a pair of second pivot holes aligned along a second pivot axis. A wireless transceiver module includes a casing formed with a pair of third pivot holes corresponding respectively to the second pivot holes, and a wire unit to connect electrically the wireless transceiver module to the connector module. The wire unit includes a pair of second pivot parts pivotally retained at aligned pairs of the second and third pivot holes to permit relative rotation between the wireless transceiver module and the coupling base about the second pivot axis.
