A finger clamping unit (FCU) is a clamp for fixing a thin panel through a toggle mechanism in which the torque input is amplified. Previous studies optimized the clamping range (range of thickness of a panel that can be clamped) using a compliant link. Thereby, panels of various thicknesses could be clamped. However, a problem occurred …

Clamping mechanism: A toggle-clamp mechanism determines how the application is clamped. These vary by the toggle-clamp design. Linkage system: This converts the linear motion of the handle or lever into a clamping action. The linkage system typically consists of a pivot point and connecting rod that transmits force and movement.

The trick behind a toggle clamp is fairly simple. The structure is made from several two-pin links (usually three, forming a 'four-bar' linkage along with the base). In the clamped position, the links are aligned, such that the clamping force is directed straight along the links, and into a fixed … See more
