Abstract: A vehicle-used suction disk retainer has a seat. The seat is installed with a suction disk and a buckling seat which are connected as an integral body. An adjusting sheet is installed in an embedding groove of the seat. As the retainer is used in a car, when the adjusting sheet is moved, the buckling seat has a force to pull a part of the suction disk to move downwards and the suction disk presses downwards. Thereby the upper and lower forces are fixed. When a reverse action is applied, it can be pulled up from the ear. Thereby the retainer can be fixed, which can be used to place a device, such as a PDA32. Furthermore, the retainer is compact, light and small volume and thus it is portable and usable.

Abstract: A satellite signal receiver used with blue tooth transmission and electronic maps comprises a box having one end extended with a shaft; two ends of the shaft having two connecting ends, respectively; a Blue tooth satellite receiver installed in the box; a lower cover having two connecting ends at one side thereof; an upper cover assembled with the lower cover so as to form an inserting card; one side of the upper cover being formed as a cambered concave edge; when the upper cover is assembled to the lower cover; the cambered concave edge is formed as an opening for receiving an SD card; and a terminal retainer received in the space between the upper cover and the lower cover; two ends of the terminal retainer being extended with respective power wires which are extended to the lower cover so as to supply power to the SD card.
