The present invention relates to a peripheral device for image display,
which comprises a hollow spot for holding the peripheral device, which
then comprises a base and a shaft, wherein the shaft was located on the
base, of which the shaft and the slot are a hole and shaft assembly case
and the shaft maintains its degree of freedom in the slot, wherein the
base can not only rotate but also slide. In addition, the base comprises
at least one positioning hole and the image display device comprises at
least one positioning pin, when the positioning hole is fitted by the
positioning pin, the degree of freedom of the rotation is thus
restricted. In comparison with prior art, the ease of use is obvious, and
the design flexibility is abundant.
