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.

A hand operated gripping tool has a first handle (301), a first jaw (201) connected with the first handle, a second handle (302) pivotably connected with the first handle to permit relative pivoting movement of the second handle with respect to the first handle and a second jaw (202) connected with the second handle. One of the first jaw and second jaw is a removable jaw and the removable jaw is push-fit attachable to the respective handle.

A purpose is to render a gripping operation of grip tabs more stable. A hose clamp includes a clamp body formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross each other on a circumferential plane and grip tabs formed to be raised radially outward from both ends of the clamp body, respectively. An expanded-diameter state of the clamp body is retained when a locking claw is locked by a catch. The clamp body is released from the expanded-diameter state when a gripping operation is further carried out in this state. The second grip tab has a distal end formed to be wider than a distal end of the first grip tab. The distal ends of the grip tabs are bent in respective directions in which the distal ends depart from each other with respect to a thicknesswise direction, thereby serving as bent portions for the gripping operation, respectively.

A linear ratchet drive mechanism operable single handedly for pivotally actuating one or more plier jaws in a diverging or converging direction for gripping objects under extreme pressure. A drive rod is received in a handle body for axial movement with one end of the drive rod pivotally linked to the jaw or jaws in order to actuate the jaws. An actuating lever is pivotally connected at one end to the handle body and extends from the handle body for single hand actuation by squeezing the lever against spring biased towards the handle body. The actuating lever is provided with a leverage arm that extends from the pivoting end of the actuating lever and is pivotally connected to a drive grip lever having an aperture surrounding the drive rod for binding against the drive rod for thereby driving the drive rod in one direction when the drive grip lever is canted and moved by squeezing the actuating lever. An incremental stop mechanism is also provided to quickly retain the jaw spacing after initial use of the device.

A lock jaw tool device may include a first beam and a second beam that may be movably coupled together in preferably two or more locations on each beam. A first jaw may be coupled to the first beam, and a second jaw may be coupled to the second beam. One or more adjustable couplings may couple the beams together and may govern the positioning of the beams relative to each other. By changing the positioning of the beams relative to each other, the positioning of the jaws relative to each other may also be changed. The one or more adjustable couplings enables the formation of fulcrums for the purpose of generating pressure on a multitude of different types of jaws. Through independent control of the one or more adjustable couplings the jaws of the beams can firmly grip or otherwise manipulate material at varying angles.
