1. A panoramic device comprising:
(a) a base having a lower first surface suitable for supporting said base; (b) a first clamp member secured for rotation to said base and comprising a first clamp surface rotatable about a single axis substantially normal to said lower first surface, said panoramic device being free from and incapable of said first clamp surface being said rotatable about an axis other than said single axis substantially normal to said lower first surface; (c) a second clamp member movably engaged with said first clamp member and movable by movement of a first member to approach said first clamp surface and clamp an article therebetween and movable by reversing movement of said first member to separate from said first clamp surface to release an article clamped between said first clamp surface and said second clamp member; and (d) a second member rotatable in a first rotational direction to increasingly impede relative rotation of said first clamp member and said base, a second member rotatable in a second rotational direction to decreasingly impede relative rotation of said first clamp member and said base, said first clamp member and said second clamp member not readily detachable from said base, said first clamp member rotatable through 360 degrees with respect to said base, wherein said first clamp member and said second clamp member not releasable from said base by movement of said second member. |
