这种活络扳手的一钳口上装有弹性滑块。向一个方向活动时,可以让过螺帽的对角。两钳口中的一个开有滑槽,目的是使它朝前移动时与另一个钳口夹紧面脱离。滑槽上装有一个带有辅助夹紧面的滑块,滑块依靠弹簧的轻轻压力,便会向后自动复位。整个结构配合得当。当扳手拧住一个螺帽反向旋转时,滑块向前端滑动,直到钳口开口距离足以让过螺帽的对角,然后弹簧便将滑块压回它原来的位置。
An elastic slider is attached to a jaw of such an adjustable wrench. When moving in one direction, you can make the diagonal of the nut. One of the jaws is provided with a chute for the purpose of disengaging it from the other jaw nip when it is moved forward. A slide with an auxiliary clamping surface is mounted on the chute and the slider automatically repositions backwards with the gentle pressure of the spring. The entire structure with proper. When the wrench is screwed on a nut and turned in the opposite direction, the slider slides forward until the jaws are open enough for the diagonal of the nut to push the slider back to its original position.
