    • 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.
    • 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。
