Abstract

A clamping force visualization device, including a first clamping body ( 01 ) for clamping an object; the first clamping body ( 01 ) is telescopically assembled on a base ( 14 ), an elastic element ( 110 ) is provided between the first clamping body ( 01 ) and the base ( 14 ), and a clamping force scale ( 11 ) and a reading indicator ( 15 ) are respectively provided on the first clamping body ( 01 ) and the base ( 14 ); when the first clamping body ( 01 ) clamps the object, the elastic element ( 110 ) measures a clamping force and the reading indicator ( 15 ) points to the clamping force scale ( 11 ) for reading, so that the magnitude of the clamping force can be intuitively seen and read during clamping, thereby achieving accurate clamping. A clamp including the clamping force visualization device is also involved.
