Provided is a clamp for fastening a portable electronic device. The clamp comprises two spring biased sliding arms and a spring biased trigger member. Pushing the trigger member toward the body will move the shuttle member upward to unlock both arms for extending thereafter. In response to sandwiching the device between the arms releasing the trigger member will push the trigger member outward and the shuttle member downward respectively for locking the ridges. In a case of the device having its ports provided at one side or both sides thereof, two central, rectangular openings of the arms are adapted to allow the ports to dispose therein for causing no interference to a normal operation of the fastened device. A distance between both arms can be adjusted by sliding one arm toward or away from the other arm or sliding both arms toward or away from each other.

A holding device for holding a portable object includes a support platform (210), a first arm (120) coupled to the support platform, a second arm (130) coupled to the support platform, a biasing member (140) located between the first and second arms, a locking mechanism (150) capable of maintaining the first arm and the second arm in any one of a plurality of discrete positions with respect to each other, and a release button (260) capable of releasing the locking mechanism adjacent to the support platform. The biasing member is capable of urging at least a portion of the first arm and at least a portion of the second arm toward each other.

A device includes a pair of arms attached to a housing for securing a portable phone to vehicles, a circuit board received in the housing and having two or more couplers for coupling to a microphone, a speaker, and for allowing the users to speak and to receive the phones without carrying the portable phone. The portable phone may be easily and readily attached to the vehicle and electrically coupled to the electric power of vehicle with a plug which may be secured to the housing with a universal joint. Various adapters may be used to selectively couple to different phones.

A panel structure capable of being attached with or detached from a supporting stand mainly comprises a base seat installed at a panel, a base plate installed at the upper end of the supporting stand and a sliding mass capable of being slid in the base seat. Whereby, the base plate in an accepting groove of the base seat can directly be pressed and positioned in the accepting groove through the sliding mass so that the panel can be chosen to be assembled with or detached from the supporting stand depending on the place and the requirement if is practically used.

A stand for a camera-equipped wireless communications device comprises a base, an adjustable terminal support movably mounted to the base, and an auxiliary system connector mounted to the base. The adjustable terminal support includes a system plug that connects to a system interface on the camera-equipped wireless communications device. The auxiliary system connector connects a peripheral device associated with the camera-equipped wireless communications device to the base. The system plug and the auxiliary system connector are interconnected by a system bus that extends through the base.
