Claims

[Scope of utility model registration request]

a plate that slides on a flat surface; a pair of arms that are rotatably disposed on the plate with a surface parallel to the flat surface about a fulcrum that is symmetrical about the sliding axis of the plate; a connecting portion disposed at the other end of the pair of arms so that the rotational movements of the pair of arms are interlocked; and a stopper provided on the plate to prevent the pair of arms from rotating beyond a certain level in the opening direction of the work chuck facing each other; A stopper pin provided on the same line as the connecting portion of the pair of arms and the slide axis of the plate and perpendicular to the plane on the work chuck side of the pair of arms, and an actuator for slidingly driving the plate. Clamp mechanism.
