ABSTRACT:
This invention has as its purpose the provision of a clamp screw in which the loss of clamping force is greatly reduced, a powerful clamping force can be obtained with a small rotational input, a sufficient clamping force can be obtained by a manual operation, and moreover, a sufficient clamping force can be obtained without excessive clamping by making effective use of the reverse thrust of the rotating tool.
With the clamp screw of the invention, when the flange ring is in contact with the object to be attached, the rotation of the threaded member stops and a clamping state is entered, the rotation of the operating ring is screw fed by the balls moving around the thread grooves, and as a result of this movement of the operating ring due to the screw feed, pressure is exerted on the flange ring through the restraining ring thus clamping the tool to be attached.
