The ZWJ-ANGLE-ADJUSTMENT (Z-A-A) is a new device that is used to adjust inclination angle or rotation angle for instruments and machines. Adjustment in the two phases can be brought about individually or simultaneously by two adjust-screws of the device. Adjustment can be achieved accurately, conveniently and smoothly. Some of common angle-adjustments, for example, the sphere-joint-angle-adjustment and camera-platform, are difficult to achieve high accuracy. The others such as worm gearing can work accurately, but they are complicated and expensive. The characteristic of the presented invention is, the angle in two phases (inclination and rotation) can be adjusted accurately in one sphere-head-shaft, adjusting in each phase (goes up and down) by one screw only. So presented invention provides a small-size device of simple structure. Also, its low production cost makes mass production possible so that potential marketing benefit is considerable.
