Abstract
The self-locking and adjustable dual ratchet clamping apparatus comprises a frame which is either a single rail or a dual rail structure having an integral ratchet rack on a side, a fixed jaw at one end of the frame, a movable jaw mounted on the frame and moves along the rail structure relative to the fixed jaw, a first ratchet system including a rotatable ratchet trigger pivotally connected to the movable jaw and is engaged with a locking pawl supported by the movable jaw to form a directional self-locking mechanism, a second ratchet system including a driving pawl engaged with the ratchet rack to form another directional self-locking mechanism, and a cascading mechanism connecting the first and second ratchet systems whereby the rotation of the rotatable ratchet trigger drives the movement of the driving pawl thereby translated into the movable jaw movement relative to the fixed jaw.
