Claims

[Claims for Utility Model Registration] A fixed clamping member having a fixed clamping surface, a movable clamping surface rotatably supported by a supporting member at an intermediate portion thereof, and a movable clamping surface cooperating with the fixed clamping surface at one end; A movable member connected to the end portion of the movable member so as to be relatively rotatable moves forward to clamp the object between the fixed clamp member, and the movable member moves back to clamp the object between the movable member and the fixed clamp member. A clamp device including a movable clamp member that releases the object, wherein the support member is movable in a direction substantially parallel to the moving direction of the movable member, and is biased by a spring in the forward direction of the movable member. and transmitting the backward movement of the moving member to the supporting member at least in the final stage of the moving member's retreating process between the supporting member and the moving member to resist the biasing force of the spring. A mechanical interlocking device is provided for moving the movable member in substantially the same direction, and the movable clamp surface is separated from the fixed clamp surface by a motion component in the forward direction of the movable member as the movable clamp member rotates back. The clamp device is characterized in that the movable clamp member is not only removed from the position facing the fixed clamp surface by a motion component in a direction perpendicular to the movable clamp member, but also the entire movable clamp member is retracted substantially in the retreating direction of the movable member. .
