Claim:
1. A clamping tool, comprising: an elongated housing defining an interior region and having first and second open ends, the elongated housing extending along a longitudinal axis; a thrust plate having an aperture extending therethrough; the thrust plate being disposed within and fixedly held in the interior region at a location proximate to the first open end; a screw member having first and second shaft portions, the first shaft portion extending through the aperture of the thrust plate and being coupled to a handle, the second shaft portion being disposed in the interior region and having threads thereon; a linearly movable actuator being disposed in the interior region, the linearly movable actuator being threadably coupled to the threads of the second shaft portion of the screw member; the linearly movable actuator having a first end plate disposed proximate to the second open end of the elongated housing, the first end plate having first and second end plate slots extending therethrough; a first clamping arm having first and second apertures extending therethrough; a first coupling member being disposed through the first aperture of the first clamping arm and the first end plate slot, and the first coupling member being slidably disposed in the first end plate slot; a second coupling member being disposed through a first aperture of the elongated housing and the second aperture of the first clamping arm, the first clamping arm being rotatable about the second coupling member; a second clamping arm having first and second apertures extending therethrough; a third coupling member being disposed through the first aperture of the second clamping arm and the second end plate slot of the first end plate, the third coupling member being slidably disposed in the second end plate slot; a fourth coupling member being disposed through a second aperture of the elongated housing and the second aperture of the second clamping arm, the second clamping arm being rotatable about the fourth coupling member; such that when the handle and the screw member rotate in a first rotational direction, the linearly movable actuator moves in a first longitudinal direction which induces the first and third coupling members to slide within the first and second end plate slots, respectively, of the first end plate, and the first and second clamping arms rotate about the second and fourth coupling members, respectively, from a first operational position to a second operational position.
