This vise is a Wilton Multi-Grip. It's a fast-acting clamp, vise and more. The clamp has a quick release, which slides back and forth so the piece can be oriented wherever needed. It also rotates so that it can be used at an angle, or turn it all the way around to make a bench vise.

The clamp can be removed from the table and if one of the heads is turned around, it can be used as a spreader. The tool attaches to the bench by tightening a thread to the side of the table. Use two of the tools together for more support.
