Clamping

— a specific type of clamp (see "Type") using a lever and/or screw mechanism (see "Compression mechanism") and used as stationary clamps. Such a clamp is attached to a certain plane, usually with the help of bolts, and the role of the working element in it is played by the stop on the swivel mount, which, when the lever is pressed, lowers to the plane and presses the fixed workpiece to it. In common parlance, such a tool is sometimes referred to as a "woodpecker" — the stroke of the stop resembles the movement of a bird's beak. The stop is usually equipped with a screw mechanism for adjusting to the thickness of the fixed part.
