Vise with vacuum base

Vacuum mechanism

— a mechanism that operates on the principle of a conventional suction cup and allows the tool to reliably “stick” to flat surfaces. The device and application of such a mechanism depend on the type and design of the tool. So, among the clamps (see "Type"), models for plates are equipped with this function (see "Design") — in such devices a pair of suction cups is provided, thanks to which the clamp is attached to the plates to be joined. But in a vice, a vacuum mechanism is used to fix the tool itself on a workbench, desktop or other base. This design is found among relatively small models — for large and heavy vices, the vacuum mechanism is poorly suited.
