The driving force transmission mechanism converts the rectilinear movement of a piston rod of the drive unit into: a first operation, in which the clamp arms rotate while moving in directions toward or away from each other; and a second operation, in which the clamp arms move in parallel in directions toward or away from each other with gripping surfaces in a mutually parallel state.

The power-boost levers are formed such that the length from a support pin toward the knuckle joint is longer than the length from the support pin toward the link arm.
