Abstract:
A clamp assembly, comprising:a first clamp handle and a second clamp handle, said pair of clamp handles being hollow inside and open on their corresponding sides; a sliding track, being a long hollow bar structure, and both ends of said sliding track along the direction of the long axis of the first clamp handle being fixed inside the first clamp handle, and a sliding hole in the same direction as the long axis being disposed on each of an upper section and a lower section of said sliding track; a clamp wire control bracket, being a plate structure substantially in the shape of a hook, having a long arm and a short arm, and a through hole being disposed,at the corner where said long and short arms intersect, and said corner being disposed inside said sliding track, and a movable wedge passing through the sliding hole and pivotally coupled into the through hole; an open end of said long arm being movably coupled to the interior of the second clamp handle and an open end of said short arm having a clamp wire fixing member; a first and a second clamp heads, each having its rear end fixed to the front end of the first and second clamp handles respectively, and the head of said first and second clamp heads stacking and pivotally coupled with each other by a movable member, and a ratcheted section being disposed on the edge of the second clamp head; a clamp wire plate being disposed at the turning head section of the first clamp head; a clamp handle torque spring, pivotally coupled on the structural surface of the second clamp head by a fixture, having two spring legs separately pressing against and being fixed on the first and second clamp handles; a clamping control plate, passing through a torque spring and pivotally coupled on the structural surface of the first clamp head ; said torque spring having one end fixed on the clamping control plate, and the other end fixed on the first clamp head; said clamping control plate at its front end having a ratcheted edge engaged with the ratcheted section of the second clamp head, and said clamping control plate at the rear end defining a poking plate bent outward; a clamp wire set, comprising a central linear member passing through a hollow elastic protective tube, and a rear end of said central linear member being fixed to said clamp wire fixing member; the rear end of said protective tube being fixed to the clamp wire plate, and the front end being sleeved by a positioning sleeve; a workpiece control set, coupled at one end of said positioning sleeve, and disposed at the front end of said clamp wire set, being a structure displaceable axially and capable of performing the opening and closing movement by the central linear member.
