摘要： A locking tool is provided that comprises an adjustment mechanism that can adjust the distance between the jaws, and the clamping force exerted by the jaws on a workpiece, using the same hand that grips the handles of the tool. A locking tool is also provided where the tool can be locked by moving the handles toward one another. Once locked, the pliers can be unlocked and the jaws opened by squeezing the handles toward one another in the same manner, in the same direction and using the same hand as was done to lock the pliers. As a result the pliers can be locked and unlocked using one-hand and using the same hand movement to both lock and unlock the pliers.
摘要翻译：提供了一种锁定工具，其包括调节机构，该调节机构可以使用夹持工具的手柄的相同的手来调节夹爪之间的距离以及由钳口施加在工件上的夹紧力。还提供了一种锁定工具，其中可以通过将把手朝向彼此移动来锁定工具。一旦锁定，钳子可以被解锁，并且通过以相同的方式在相同的方向上彼此挤压手柄而打开钳口，并且使用相同的手来锁定钳子。因此，钳子可以使用单手锁定和解锁，并使用相同的手部移动来锁定和解锁钳子。

摘要： The self-adjusting locking pliers include a fixed assembly having a fixed jaw supported at one end. A moveable jaw is pivotably supported on the fixed assembly at a slidable pivot connection. The slidable pivot connection includes a pawl provided with teeth. A rack of teeth includes first and second sets of teeth offset from one another by ½ of the pitch that may each be engaged by the teeth formed on pawl. A lever is attached to the fixed assembly and a linkage transmits a force applied to the lever to the jaws and locks the jaws in the clamping position. The linkage allows the angle between the links to be preset to thereby control the clamping force applied to the work piece. The movable jaw is selectively attached to the linkage in one of two positions such that the jaw span may be adjusted without affecting the geometry of the linkage.
摘要翻译：自调节锁定钳包括固定组件，其具有在一端支撑的固定夹爪。可动爪在可滑动的枢转连接处可枢转地支撑在固定组件上。可滑动的枢转连接包括设置有齿的棘爪。齿条包括第一和第二组彼此偏移的距离的1/2，每个齿可以分别由形成在棘爪上的齿接合。杠杆附接到固定组件，并且连杆将施加到杠杆的力传递到钳口并将钳口锁定在夹紧位置。联动装置允许链接之间的角度被预先设定，从而控制施加在工件上的夹紧力。活动夹爪在两个位置中的一个位置选择性地附接到连杆机构，使得可以调节夹爪跨距而不影响连杆的几何形状。

摘要： A method of operating a clamp (100) that includes a first clamping jaw (102), a support element (104) to which the first clamping jaw is attached and a trigger handle (118) pivotably mounted to a clamp body (112). The method includes actuating the trigger handle causing the first clamping jaw to experience incremental motion and varying the incremental motion as a function of a load encountered by the support element by varying an effective lever arm of the trigger handle by moving a fulcrum point into contact or out of contact with the trigger handle based on the load.

摘要： A first member defines an aperture between the jaw and the handle that is defined by a first side wall and a second side wall where the first side wall, second side wall and handle may be integrally formed as a unitary piece. The jaws may also be formed integrally with the handle and side walls. The second member includes an elongated slot and a row of teeth. A pivot member extends along the axis of rotation and includes a tooth engageable with the row of teeth. The pivot member moves between a first position where the teeth are engaged and movement of the first jaw away from the second jaw is prevented and a second position where the teeth are disengaged and movement of the first jaw away from the second jaw is permitted.

摘要： The locking pliers comprise a first handle connected to a fixed jaw. A second handle and second jaw are pivotable relative to the first handle and first jaw such that relative movement of the handles causes the jaws to open and close. A toggle-locking mechanism locks the jaws in the closed position. An adjustment screw is provided to vary the effective length of the toggle locking mechanism to control the distance between the jaws in the closed position and to thereby control the force applied by the jaws. The adjustment screw comprises a head that has a knurled outer periphery that can be manually manipulated. A socket is formed in the transverse face of the screw head that is disposed along the longitudinal rotational axis of the screw. The socket has an internal configuration that receives a torque applying tool.
