ABSTRACT:
The invention, of toggle principle to hold and join two tubes or shafts, has 3 main parts, which do not wear, have great strength which can be increased by increasing the width of its 3 parts, which can be attached together by adhesive and two flexible rubber strips. It can be dynamically balanced to connect rotating shafts. It can be self-adjustable when its band is corrugated spring steel. It has many advantages and is suitable for many more applications than conventional clamps. It is a universal clamp, simple, easy to manufacture, economical, and can be used over and over again. It is the answer for many applications, easy to operate by engaging the inwardly opening eye shaped end of a handle-lever in one outwardly opening eye shaped end of a band and in the meantime the handle-lever is pivotally engaged with one end of a third member which at its other end is pivotally engaged with the other outwardly opening eye shaped end of the band and then rotating the handle-lever toward the band to its final position, passing by the dead center of this toggle mechanism.
