The clamp assembly includes a body portion provided with a screw hole, a forward protrusion formed at the front portion of the body and extending downward, a rear protrusion formed at the rear end portion of the body and extending downward, and a bridge connecting the forward protrusion and the central portion of the body. The clamp assembly also includes a pressing plate having upper and lower surfaces, a front nose portion, a rear end portion, and is provided with a keyhole shaped groove having an enlarged inner cavity open toward the rear end by a narrow neck extending thicknesswise.
