FASTENING CLAMP Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: legs of the clamp are beveled from the outer side. The surfaces of the bevels are perpendicular to the plane tangent to the inner sides of the lags that face each other. Behind the bevels are inclined surfaces, the angle of inclination of which is less than the angle of inclination of bevels. The outer and inner surfaces of the lags of the clamp can be provided with hollows. The diameter of the hollows decreases with height of lags in the direction from the cutting edges to the cross-piece of the clamp. EFFECT: enhanced reliability. 4 cl, 5 dwg
