Abstract
A cardan shaft structure with tightness adjustable functions has a through-hole passing through spheres located at both ends of the cardan shaft body, and a taper socket respectively installed into the opening end of each sphere. A bolt is inserted into both spheres and the body, fixed and locked together in conjunction with a nut. The cardan shaft structure works together with two clamping components wrapping around the spheres. When the sphere is being pushed against (or freed from) the inner wall of the clamping component by tightening (or loosing) the bolt so as to make the sphere either expand (or recover), the angle displacement of the clamping component becomes adjustable accordingly.
