使用扳手之前先將需要的實(shí)際擰緊扭矩值預(yù)置在扳手上面，當(dāng)數(shù)值相等的時(shí)候，扳手會(huì)發(fā)出警報(bào)聲，扭矩扳手手柄上有窗口，窗口內(nèi)有標(biāo)尺，標(biāo)尺上顯示扭矩值的大小。
Before using the wrench, preset the actual tightening torque value required on the wrench. When the values are equal, the wrench will sound an alarm, and there is a window on the torque wrench handle with a ruler inside, which displays the size of the torque value.

Before using the wrench, preset the actual tightening torque value required on the wrench. When the values are equal, the wrench will sound an alarm. There is a window on the handle of the torque wrench, and there is a ruler inside the window, which displays the size of the torque value. There are two types of torque wrenches: fixed value type and preset type. The preset adjustable torque wrench refers to the adjustable pre tightening value of the torque, which users can adjust according to their needs. Before using the wrench, the actual tightening torque needs to be preset on the wrench, when tightening threaded fasteners.
如果實(shí)際扭矩與預(yù)緊扭矩值相等，扳手就會(huì)發(fā)出警報(bào)聲，此時(shí)停止扳手，扳手釋放后會(huì)自動(dòng)的設(shè)定預(yù)緊扭矩值，為下一次工作做準(zhǔn)備；還有一種方法是自己看扳手上的扭力值，扳手手柄上有一個(gè)窗口，窗口內(nèi)的標(biāo)尺會(huì)標(biāo)出具體的扭力值。設(shè)定預(yù)緊扭矩值的方法是先松開(kāi)扭矩扳手尾部的尾蓋，然后旋轉(zhuǎn)扳手尾部手輪就行。使用扭矩扳手一般要注意使用前要進(jìn)行檢查，裝配零件是否達(dá)到所需數(shù)值；查看是否有零件缺失等事項(xiàng)。
If the actual torque is equal to the pre tightening torque value, the wrench will sound an alarm, stop the wrench, and after the wrench is released, it will automatically set the pre tightening torque value to prepare for the next work; Another method is to check the torque value on the wrench yourself. There is a window on the wrench handle, and the ruler inside the window will indicate the specific torque value. The method to set the pre tightening torque value is to first loosen the tail cover of the torque wrench, and then rotate the handwheel at the tail of the wrench. When using a torque wrench, it is generally important to check whether the assembled parts have reached the required value before use; Check for any missing parts or other issues.
