<p>PROBLEM TO BE SOLVED: To provide a clamp with high reliability capable of cooperating with a cable in a simple structure by allowing an elbow lever and a link to rotate on a parallel or the same vertical surface and arranging toggle lever link into a substantially horizontal linear state at a cable clamping position. SOLUTION: At an extension location, a toggle lever is on the upper side of a hinge pin 25 of an elbow lever 26 and is substantially horizontal. A second link holds a horizontal arm 35 and the horizontal arm 35 is hinge-coupled with a rod of a hydraulic or pneumatic actuator 37, for instance, to operate extension or folding of the toggle lever. Each of pairs of the elbow lever 26, the second link and the actuator 37 is provided. Thus, an objective type device is formed. As a result, reliability with high operability is secured.</p> |
