Abstract

PURPOSE: To lock in an ensured way and release the lock simply by manipulating the manipulating handle together with a lock handle mounted on the handle, always attaching to the lock position by spring force. CONSTITUTION: When a manipulating handle 12 is rotated by manipulation from a non-manipulating position to a manipulating position, a clamp 15 is rotated from a released position to an actuating position by a ring 17, and a lock member 20 is swung to the lock position by the attaching spring force to bind the manipulating handle 12 in that position. In this way, the clamp 15 in working position is locked. When the manipulating handle 12 and a lock handle 21 are gripped together and manipulated to the non-manipulating position, the binding of the manipulating handle 12 by the lock member 20 is released, and it is possible to rotate the handle by manipulation to the manipulating position. As the manipulating handle 12 and the lock handle 21 are so arranged that they can be gripped together, to release the lock is easy.
