Quick release, wedge type cam action

The clamp’s lever has a wedge type cam. When the lever is at rest, it hangs downwards, permits this way to locate the workpiece. We rotate the lever counterclockwise (rotates only in one direction), and we push it. The cam cinches the lever and clamps the workpiece.
This clamp is very simple in design, just be carefully with:
• When the lever hangs down the workpiece must pass through to the reference shaft.
• The upper hole of the lever must be calculated correctly in order the lever freely rotates when the workpiece is in clamping position.
