Abstract

The self-adaptive self-locking clamping apparatus comprises a pair of arms pivotally interconnected to each other via a fulcrum either in the middle or on one end of the pair of arms, forming a pair of jaws with at least a variable gap for load, a fulcrum and a pair of handles for effort. The pair of handles engage with each other via a pawl and ratchet mechanism to achieve directional self-locking function, so that the clamping force applied to the pair of handles are maintained after such clamping force is removed. The self-locking pawl and ratchet engagement is self-adaptive to the geometric deformation of the pair of arms resulted from the elastic deformation caused by the clamping force, creating a firm locking grip so that a user does not have to keep maintaining the clamping force while in operation.
