Abstract
The present invention discloses a force relieving mechanism and a ratchet clamp having a force relieving mechanism. The force relieving mechanism includes a first ratchet member, a second ratchet member, a locking member, an actuating member and a restoring member. A first clamp arm of the ratchet clamp is fixedly arranged with a first ratchet member having a first set of ratchets, and a second ratchet member having a second set of ratchets is coupled to the second clamp arm. The second ratchet member is provided with a first hole, the locking member passing through the first hole and being rotatable and translationally movable in the first hole. The actuating member applied a first actuation and a second actuation in turn to the locking member so as to cause the second set of ratchets to be detached from the first set of ratchets.
