käehaarde

A käehaarde, literally translating to "hand grip" in Estonian, is a type of mechanical fastener. It is primarily used to secure objects or components by employing a gripping mechanism that is actuated by hand. The design typically involves a lever or handle that, when manipulated, causes jaws or other gripping surfaces to engage with the object being held.

Käehaardes are common in various industrial and domestic applications where frequent and quick fastening or loosening is required. They offer a convenient alternative to more complex or time-consuming locking mechanisms. Examples can be found in machinery, workbenches, bicycle components, and even in some types of adjustable furniture. The principle behind their operation is simple leverage, allowing for a significant clamping force to be applied with minimal effort.

The materials used in the construction of a käehaarde can vary depending on the intended load and environment, ranging from simple steel or aluminum to more robust alloys for heavy-duty applications. Their ease of use and effectiveness make them a practical solution for many fastening needs.
