Each stamped part has at least two engagement holes for engagement elements which kinetically interact with the functional component. The engagement holes in the stamped parts are arranged congruently with respect to one another.

Abstract: A unitary stackable fence module having end assemblies and span members is provided for forming a perimeter fence having an inwardly inclined profile. A right angle end support has vertical and horizontal members and an angle arm, spaced from and attached to a side edge of the vertical and horizontal members adjacent the span members. The unique arrangement permits a plurality of fence modules to be stacked for transport or storage. Loops formed on the vertical members permit pivotal pinning of fence modules together to form perimeter fences of any polygonal shape.

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.
