The present invention relates to a fixing device for assembling a device such as an audio visual to a support such as an arm.

In recent years, devices such as liquid crystal televisions are provided in a vehicle interior. Usually, the liquid crystal television is fixed to the base plate formed at the tip of the arm as a support by a fastening screw.

However, in order to enjoy liquid crystal television outdoors or to prevent theft, the liquid crystal television may be detached from the arm when the passenger gets off.

However, in the conventional fixed structure, it is necessary to remove the fastening screw and to detach the liquid crystal television from the arm, which takes time to attach and detach. Therefore, it is also conceivable to use a camera fixing device (JP-A-62-43189) as a fixing device for liquid crystal television. The camera fixing device is adapted to slide and detach the movable shoe fixed to the camera side with respect to the slide groove of the base plate fixed to the triangular leg side. This is a projection piece capable of elastic deformation.

However, if the above-described fixing structure is applied to the liquid crystal television provided in the interior of the vehicle, the liquid crystal television does not fall upward, but the protrusions as stoppers are deformed due to the shaking or vibration of the vehicle and the liquid crystal television follows the slide groove. There is a risk of sliding off the arm.

In consideration of the detachable operation, it is easier to lift and detach the liquid crystal television from the arm than to slide the liquid crystal television off.

In addition, unlike a camera, it is necessary to connect a power supply and an antenna to a liquid crystal television, and therefore, it is preferable that the connection work is completed at the same time as the detachable operation.
